To this date, we have only been able to develop non-living protobionts in the lab, and nothing else beyond this point. True False Montmorillonite clay is important in that it is thought to have facilitated the process of abiogenesis by expediting/facilitating the formation of complex self-replicating molecules, and the generation of phospolipid bilayers that might have assembled into the first cell membranes. True False One of the limitations of the current fossil record in our planet is that it is biased in favor of the species that have left hard bony structures and/or had lived for a long periods of time. True False Tappania plana, an example of the first unicellular prokaryotes, is thought to be an alga or a fungus. True False Early in 2017 scientists have discovered a new family of eukaryotic bacteria in the thermal vents of Iceland. These eubacteria - named Locky and Aasgard after the Nordic Viking gods-are thought to be the source of all eukaryotic cells in the planet. True False Solution 37: FALSE: Protobionts are the aggregrates of organic polymers that are supposed to be spontaneously formed under certain conditions through chemical evolution. To this date, the living protobionts have been synthesized in the lab which exhibit all the properties of living cell except using DNA to program the protein synthesis..

This document discusses the origin of life on Earth. It describes early theories on how life may have originated from organic molecules formed from chemical reactions, including the Miller-Urey experiment. It also discusses how early life may have originated near hydrothermal vents and how the first cells were prokaryotic. The document then covers the development of eukaryotic cells through endosymbiosis and the oxygenation of the atmosphere by cyanobacteria, enabling the evolution of more complex multicellular life.

This document discusses theories on the origin of life and the earliest life forms. It explores the hypothesis that life began through extraterrestrial origins, panspermia, divine creation, or from nonliving matter on Earth. The primordial soup theory proposed that organic molecules combined in Earth's early atmosphere to form self-replicating molecules. Evidence for early life includes Miller-Urey experiments showing amino acid formation from atmospheric gases, as well as microfossils of cyanobacteria and stromatolites, some of the earliest fossils, dating back billions of years.

The origin of life on Earth is still uncertain, but scientists believe the first life forms were single-celled organisms that appeared around 3.5 billion years ago. Over millions of years, these simple cells evolved into more complex multicellular organisms through a process of natural selection and mutations. While early theories proposed that life could spontaneously generate from non-living matter, it is now widely accepted that all living things on Earth descended from a common primitive ancestor, likely a basic bacterium. Researchers continue to study how the building blocks of life first formed and how conditions on early Earth allowed life to emerge and evolve.
D1 origin of life
The document outlines the key processes thought to be necessary for the spontaneous origin of life on Earth: 1) The synthesis of simple organic molecules, as demonstrated by the Miller-Urey experiment; 2) The assembly of these molecules into polymers like polypeptides; 3) A mechanism for inheritance, proposed to be self-replicating RNA; 4) The development of membranes. These processes are hypothesized to have led to the formation of "protobionts", early cell-like structures surrounded by membranes. The endosymbiotic theory proposes that eukaryotic cells arose from engulfed prokaryotes that evolved to become organelles like mitochondria and chloroplasts. Early prokaryotes also produced oxygen as

Our planet has always been in the “Age of Bacteria,” ever since the first
fossils—bacteria of course—were entombed in rocks more than 3 billion
years ago. On any possible, reasonable criterion, bacteria are—and always
have been—the dominant forms of life on Earth.

Chapter Preview and Key Concepts
“Double, double toil and trouble; Fire burn, and cauldron bubble” is the
refrain repeated several times by the chanting witches in Shakespeare’s
Macbeth (Act IV, Scene 1). This image of a hot, boiling cauldron actu-
ally describes the environment in which many bacterial, and especially
archaeal, species happily grow! For example, some species can be iso-
lated from hot springs or the hot, acidic mud pits of volcanic vents
( FIGURE 4.1 ).
When the eminent evolutionary biologist and geologist Stephen J. Gould
wrote the opening quote of this chapter, he as well as most microbiologists
had no idea that embedded in these “bacteria” was another whole domain
of organisms. Thanks to the pioneering studies of Carl Woese and his col-
leagues, it now is quite evident there are two distinctly different groups of
“prokaryotes”—the Bacteria and the Archaea (see Chapter 3). Many of the
organisms Woese and others studied are organisms that would live a happy
life in a witch’s cauldron because they can grow at high temperatures, produce
methane gas, or survive in extremely acidic and hot environments—a real
cauldron! Termed extremophiles, these members of the domains Bacteria

ORIGIN OF LIFE.pptx
Life, living matter are those that shows certain attributes that include responsiveness, growth, metabolism, energy transformation and reproduction.
In biology origin of life or abiogenesis is the natural process by which life has arisen from non-living matter, such as simple organic compounds.
It means the emergence of heritable and evolvable self-reproduction.
It is a complex subject and oftentimes controversial.
Several attempts have been made from time to time to explain the origin of life on earth.
There are several theories which offer their own explanation on the possible mechanism of origin of life.
THE CONCEPT OF LIFE BASED ON.pptx
The document discusses theories on the origin of life on Earth and evidence that supports how early life began. It describes how scientists believe life first emerged around 3.5 billion years ago based on evidence from microfossils. Early life forms were prokaryotes like cyanobacteria that existed in mats and stromatolites. Cyanobacteria were some of the first organisms to produce oxygen, changing the atmosphere to support more complex life. Further evidence from fossil layers shows the evolution of diverse plants and animals over time.
History Life APBioCh17
The document discusses the history of life on Earth from its origins through the development of early organisms and eventual emergence of humans. It describes how early Earth's atmosphere likely allowed for the formation of organic molecules through chemical reactions, and may have given rise to self-replicating molecules like RNA. The evolution of photosynthesis introduced oxygen to the atmosphere, and energy harvesting aerobic cells became dominant. Eukaryotic cells later emerged through endosymbiotic relationships between cells and engulfed prokaryotes like mitochondria and chloroplasts. Multicellular life then diversified over millennia as plants and animals evolved on land and in the seas.

ELS-DLP Q2 -The Origin of the First Life Forms on Earth.docx
The document is a daily lesson plan for an 11th grade class on the origin of the first life forms on Earth. The objectives are for students to understand the importance of all life forms, explain the origin of the first life forms, and describe the pre-conditions that allowed early life to emerge. The lesson will discuss how the first prokaryotic cells formed around 3.4 billion years ago based on evidence from ancient rocks. It will explain how oxygen-producing photosynthesis led to a rise in oxygen levels and the evolution of aerobic respiration. The lesson evaluates students' understanding through multiple choice questions about early life forms, including prokaryotes, endosymbiosis, and anaerobic metabolism.

Later scientists like Robert Hooke used microscopes to observe plant and animal cells for the first time.
B.tech biotech i bls u 1.2 theories of origin of life
The document discusses several theories regarding the origin of life on Earth:
1) Special creation theory proposes that life was created by a supernatural power.
2) Early experiments provided evidence that simple organic molecules could form from inorganic compounds.
3) Later, more complex organic molecules like amino acids were found to arise spontaneously from simpler precursors.
4) Modern hypotheses suggest life began through gradual chemical evolution, with self-replicating molecules like RNA emerging and eventually becoming enclosed in cell membranes.
Chapter 15
The document describes the conditions on early Earth that enabled the origin of life and the key events in the evolution of life over billions of years. It explains that the early atmosphere differed from today's and was conducive to the abiotic synthesis of organic molecules. The earliest evidence of life comes from 3.5-billion-year-old fossils, and life may have originated as early as 3.9 billion years ago. Major events included the emergence of single-celled and then multicellular organisms, and plants and fungi colonizing land around 500 million years ago. Continental drift also played a role in shaping the diversity of life.
chapt. 9 nannofossil coccolithophores (1).pptx
This document provides information about nannofossils, specifically coccolithophores. It defines nannofossils as the smallest members of plankton, usually 5-60 micrometers in size. Coccolithophores are one-celled plant-like organisms that surround themselves with calcite plates called coccoliths. They are classified taxonomically and ecologically dominate warm surface waters, where their calcareous remains can form deposits like chalk. The geological record of calcareous nannofossils dates back to the late Triassic. Their small size, widespread distribution, and good preservation make them useful for biostratigraphy.
Bio17 The History of Life
The document summarizes key events in early Earth history based on evidence from the fossil record:
- Early Earth had a toxic atmosphere but cooled enough for liquid water oceans to form around 3.8 billion years ago. Early organic molecules formed in simulations of Earth's atmosphere.
- The first life forms were unicellular bacteria that evolved around 3.5 billion years ago without oxygen. Photosynthetic bacteria introduced oxygen to the atmosphere around 2.2 billion years ago.
- Eukaryotic cells evolved from symbiotic relationships between prokaryotes around 2 billion years ago, resulting in mitochondria and chloroplasts. Sexual reproduction and multicellularity further increased genetic variation.
Primey cell
The document discusses the origin of life on Earth from the formation of the universe to early theories on how life began. It describes how around 4 billion years ago, the early Earth had a reducing atmosphere of gases like methane and ammonia. Experiments in the 1950s showed that conditions in the early Earth could produce amino acids and other organic molecules (Miller-Urey experiment). Debates continue around whether RNA or proteins came first, with proposals that self-replicating RNA arose inside early lipid membranes to form the first protocells.

Please help! Both answers must be in long paragraph form
1. Explain in detail Where did the chloroplast organelle come from, what is it\'s \"origin story\",
what evidence supports this idea originally developed by Lynn Margulis?
2. Explain in detail What is the importance of chloroplasts to living things other than plants?
What are products they make, and how did one of the waste products generated change the
history of the planet earth?
Solution
Ans 1: Chloroplast Origin: The credit for discovery of this organelle goes to Julius Von Sachs. In
Year 1837, German botanist Hugo von Mohl provided the first definitive description of the
chloroplast, which is descrite bodies within the green plant cell. Later, The name was changed to
plastid by A.F. W Schimper in 1883. By the end of 19th century chloroplast name was accepted
in scientfic community worldwide to the cell- organelle which is green color found in plant
tisuue. One major discovery was also found by schimper that chloroplast are capable of division.
He suggest that origin of green pant was possibly by symbiotic relationship between chlorophyll
containing and colorless organism. Another important observation was made by A. meyer in
1883 that chloroplast contain grana. Chloroplast are only found in green plant,algae etc. Green
Color present in plant is only due to chloroplast.
Lynn Margulis was a evolutionist, she suggest that photosynthesis process which occur in plant
due to symbiosis relationship between plant cell and bacteria,which reside permanently there, by
which chloroplast capture sunlight energy undergoes biochemical reaction including
combination of water and carbon di oxide to make organic matter. Margulis symbisis thought of
evolution of eukaryotic cell was published in \" The Origin of Eukaryotic Cells.\"
Ans 2 : Importance of chloroplast is in the process of photosynthesis take place in algae, which is
also eukayotes. Many are unicellular, but sometimes they can live in large colonies that may
even look like plants.
Cynobacteria are prokaryotes contain double outer membrane and thylakoid membrane system
for the process of photosyntheis. Cyanobacteria also use the Calvin cycle to fix carbon dioxide in
the same way as plants and algae. Both of the above organism perform oxygenic photosynthesis.
similar way green sulphur, green non sulphur and heliobacteria use choloroplast for the process
of photosynthesis.
Two and a half billion years ago, single-celled organisms called cyanobacteria harnessed
sunlight to split water molecules, producing energy to power their cells and releasing oxygen
into an atmosphere that had previously had none. These early environmental engineers are
responsible for the life we see around us today. Oxygen which is one of the waste product
generated during photosynthesis change the history of the planet earth and all the higher level
living organism are able to live their life easily..
Questions1) How does multimedia transmission differ than messag.pdf
Questions:
1) How does multimedia transmission differ than \'message\' transmission?
2) Describe compression and include the different types used in multimedia.
Solution
1)
Message transmission includes the standard text communication using standard communication
protocols. Here the messages are generally short and fixed in length. Message Service Centres
(MSCs) are responsible for sending and receiving of messages. These messages are stored and
forwarded and in case of any failure, they are queued for resending. The message if successfully
sent, is then discarded from storage.
Multimedia transmission is a way to send messages that includes multimedia content like
images, music or video files. Message Service Centres along with carriers are responsible for
successful sending and receiving of messages. Carriers are mainly used to change the format of
the Multimedia message because the formats supported on different targeted devices are
different. Internet is required to transfer multimedia messages between carrier and carrier. If the
target device does not support multimedia, these messages can be viewed on the browser through
an URL send as text message.
2)
Compression is reduction in size of a file by reducing the number of bits that are used to
represent without any loss of data. Generally, compression is employed to save storage space and
increase the pace of file sending over a network which in turn saves bandwidth. An algorithm is
used to compress a file.
Multimedia compression techniques are classified as
Lossy Compression: These recover the somewhat a similar representation to the original file.
They have high compression ratios and used more practically.
Examples of Lossy compression techniques are
Lossless Compression: These techniques recover the original file.
Examples of lossless techniques are.

ORIGIN OF LIFE.pptx
Life, living matter are those that shows certain attributes that include responsiveness, growth, metabolism, energy transformation and reproduction.
In biology origin of life or abiogenesis is the natural process by which life has arisen from non-living matter, such as simple organic compounds.
It means the emergence of heritable and evolvable self-reproduction.
It is a complex subject and oftentimes controversial.
Several attempts have been made from time to time to explain the origin of life on earth.
There are several theories which offer their own explanation on the possible mechanism of origin of life.
THE CONCEPT OF LIFE BASED ON.pptx
The document discusses theories on the origin of life on Earth and evidence that supports how early life began. It describes how scientists believe life first emerged around 3.5 billion years ago based on evidence from microfossils. Early life forms were prokaryotes like cyanobacteria that existed in mats and stromatolites. Cyanobacteria were some of the first organisms to produce oxygen, changing the atmosphere to support more complex life. Further evidence from fossil layers shows the evolution of diverse plants and animals over time.
History Life APBioCh17
The document discusses the history of life on Earth from its origins through the development of early organisms and eventual emergence of humans. It describes how early Earth's atmosphere likely allowed for the formation of organic molecules through chemical reactions, and may have given rise to self-replicating molecules like RNA. The evolution of photosynthesis introduced oxygen to the atmosphere, and energy harvesting aerobic cells became dominant. Eukaryotic cells later emerged through endosymbiotic relationships between cells and engulfed prokaryotes like mitochondria and chloroplasts. Multicellular life then diversified over millennia as plants and animals evolved on land and in the seas.

1. Plants provide the foundation of life by producing oxygen, building soil, holding soil in place, moderating climate, holding water, and providing food, fuel, fiber and drugs for humans.
2. Important adaptations that enabled plants to live on land include developing mechanical strength for support, light-catching leaves, roots for anchoring and obtaining nutrients, stomata and cuticles to control water loss, and methods of reproduction and dispersal on dry land.
3. Major plant groups evolved over time in relationship to environmental changes. Early land plants included lycophytes and horsetails, which were later joined by seed plants including gymnosperms and later angiosperms, allowing colonization of new

ELS-DLP Q2 -The Origin of the First Life Forms on Earth.docx
The document is a daily lesson plan for an 11th grade class on the origin of the first life forms on Earth. The objectives are for students to understand the importance of all life forms, explain the origin of the first life forms, and describe the pre-conditions that allowed early life to emerge. The lesson will discuss how the first prokaryotic cells formed around 3.4 billion years ago based on evidence from ancient rocks. It will explain how oxygen-producing photosynthesis led to a rise in oxygen levels and the evolution of aerobic respiration. The lesson evaluates students' understanding through multiple choice questions about early life forms, including prokaryotes, endosymbiosis, and anaerobic metabolism.

This document provides a summary of the history and development of the microscope. It discusses how early Dutch lens makers invented the compound microscope in the 16th century and how Galileo and others later improved its design. It describes how Antony van Leeuwenhoek made additional improvements allowing up to 270x magnification and how he was the first to observe bacteria, blood cells, and other microorganisms. Later scientists like Robert Hooke used microscopes to observe plant and animal cells for the first time.
B.tech biotech i bls u 1.2 theories of origin of life
The document discusses several theories regarding the origin of life on Earth:
1) Special creation theory proposes that life was created by a supernatural power.
2) Early experiments provided evidence that simple organic molecules could form from inorganic compounds.
3) Later, more complex organic molecules like amino acids were found to arise spontaneously from simpler precursors.
4) Modern hypotheses suggest life began through gradual chemical evolution, with self-replicating molecules like RNA emerging and eventually becoming enclosed in cell membranes.
Chapter 15
The document describes the conditions on early Earth that enabled the origin of life and the key events in the evolution of life over billions of years. It explains that the early atmosphere differed from today's and was conducive to the abiotic synthesis of organic molecules. The earliest evidence of life comes from 3.5-billion-year-old fossils, and life may have originated as early as 3.9 billion years ago. Major events included the emergence of single-celled and then multicellular organisms, and plants and fungi colonizing land around 500 million years ago. Continental drift also played a role in shaping the diversity of life.
chapt. 9 nannofossil coccolithophores (1).pptx
This document provides information about nannofossils, specifically coccolithophores. It defines nannofossils as the smallest members of plankton, usually 5-60 micrometers in size. Coccolithophores are one-celled plant-like organisms that surround themselves with calcite plates called coccoliths. They are classified taxonomically and ecologically dominate warm surface waters, where their calcareous remains can form deposits like chalk. The geological record of calcareous nannofossils dates back to the late Triassic. Their small size, widespread distribution, and good preservation make them useful for biostratigraphy.
Bio17 The History of Life
The document summarizes key events in early Earth history based on evidence from the fossil record:
- Early Earth had a toxic atmosphere but cooled enough for liquid water oceans to form around 3.8 billion years ago. Early organic molecules formed in simulations of Earth's atmosphere.
- The first life forms were unicellular bacteria that evolved around 3.5 billion years ago without oxygen. Photosynthetic bacteria introduced oxygen to the atmosphere around 2.2 billion years ago.
- Eukaryotic cells evolved from symbiotic relationships between prokaryotes around 2 billion years ago, resulting in mitochondria and chloroplasts. Sexual reproduction and multicellularity further increased genetic variation.
Primey cell
The document discusses the origin of life on Earth from the formation of the universe to early theories on how life began. It describes how around 4 billion years ago, the early Earth had a reducing atmosphere of gases like methane and ammonia. Experiments in the 1950s showed that conditions in the early Earth could produce amino acids and other organic molecules (Miller-Urey experiment). Debates continue around whether RNA or proteins came first, with proposals that self-replicating RNA arose inside early lipid membranes to form the first protocells.

Please help! Both answers must be in long paragraph form
1. Explain in detail Where did the chloroplast organelle come from, what is it\'s \"origin story\",
what evidence supports this idea originally developed by Lynn Margulis?
2. Explain in detail What is the importance of chloroplasts to living things other than plants?
What are products they make, and how did one of the waste products generated change the
history of the planet earth?
Solution
Ans 1: Chloroplast Origin: The credit for discovery of this organelle goes to Julius Von Sachs. In
Year 1837, German botanist Hugo von Mohl provided the first definitive description of the
chloroplast, which is descrite bodies within the green plant cell. Later, The name was changed to
plastid by A.F. W Schimper in 1883. By the end of 19th century chloroplast name was accepted
in scientfic community worldwide to the cell- organelle which is green color found in plant
tisuue. One major discovery was also found by schimper that chloroplast are capable of division.
He suggest that origin of green pant was possibly by symbiotic relationship between chlorophyll
containing and colorless organism. Another important observation was made by A. meyer in
1883 that chloroplast contain grana. Chloroplast are only found in green plant,algae etc. Green
Color present in plant is only due to chloroplast.
Lynn Margulis was a evolutionist, she suggest that photosynthesis process which occur in plant
due to symbiosis relationship between plant cell and bacteria,which reside permanently there, by
which chloroplast capture sunlight energy undergoes biochemical reaction including
combination of water and carbon di oxide to make organic matter. Margulis symbisis thought of
evolution of eukaryotic cell was published in \" The Origin of Eukaryotic Cells.\"
Ans 2 : Importance of chloroplast is in the process of photosynthesis take place in algae, which is
also eukayotes. Many are unicellular, but sometimes they can live in large colonies that may
even look like plants.
Cynobacteria are prokaryotes contain double outer membrane and thylakoid membrane system
for the process of photosyntheis. Cyanobacteria also use the Calvin cycle to fix carbon dioxide in
the same way as plants and algae. Both of the above organism perform oxygenic photosynthesis.
similar way green sulphur, green non sulphur and heliobacteria use choloroplast for the process
of photosynthesis.
Two and a half billion years ago, single-celled organisms called cyanobacteria harnessed
sunlight to split water molecules, producing energy to power their cells and releasing oxygen
into an atmosphere that had previously had none. These early environmental engineers are
responsible for the life we see around us today. Oxygen which is one of the waste product
generated during photosynthesis change the history of the planet earth and all the higher level
living organism are able to live their life easily..

Questions1) How does multimedia transmission differ than messag.pdf
Questions:
1) How does multimedia transmission differ than \'message\' transmission?
2) Describe compression and include the different types used in multimedia.
Solution
1)
Message transmission includes the standard text communication using standard communication
protocols. Here the messages are generally short and fixed in length. Message Service Centres
(MSCs) are responsible for sending and receiving of messages. These messages are stored and
forwarded and in case of any failure, they are queued for resending. The message if successfully
sent, is then discarded from storage.
Multimedia transmission is a way to send messages that includes multimedia content like
images, music or video files. Message Service Centres along with carriers are responsible for
successful sending and receiving of messages. Carriers are mainly used to change the format of
the Multimedia message because the formats supported on different targeted devices are
different. Internet is required to transfer multimedia messages between carrier and carrier. If the
target device does not support multimedia, these messages can be viewed on the browser through
an URL send as text message.
2)
Compression is reduction in size of a file by reducing the number of bits that are used to
represent without any loss of data. Generally, compression is employed to save storage space and
increase the pace of file sending over a network which in turn saves bandwidth. An algorithm is
used to compress a file.
Multimedia compression techniques are classified as
Lossy Compression: These recover the somewhat a similar representation to the original file.
They have high compression ratios and used more practically.
Examples of Lossy compression techniques are
Lossless Compression: These techniques recover the original file.
Examples of lossless techniques are.

On January 1, 2002, Germany officially adopted the euro as its curre.pdf
On January 1, 2002, Germany officially adopted the euro as its currency, and deutsche mark
stopped being legal tender. According to the Article in the Wall Street Journal, even 10 years
later many stores in Germany continued to accept it. Briefly explain how possible for people to
continue to use a currency when government replaced it with another currency.
Source: Who needs the euro When You Can Pay with Deutsche Marks? Wall Street Journal July,
2012
Solution
The most important function of money is that it is used as medium of exchange. In other words,
it can be used for payment of goods and services.
Money is able to act as medium of exchange because it possesses the quality of general
acceptability.
Anything that is generally acceptable can act as money and thus can be used as medium of
exchange.
Quality of general acceptability is the key and not the government undertaking.
Many people across Germany are still accepting deutsche mark as medium of exchange and due
to this general acceptability it is still being used as medium of exchange even though German
government has discontinued deutsche mark and adopted the Euro.
Adoption of a currency by government makes it legal tender in the country concerned but it does
not guarantee that it will be used as medium of exchange unless and until it is generally
acceptable.
Thus, it is possible for people to continue using a currency when government replaced it with
another currency if the currency being used by the people is still generally acceptable as medium
of exchange. This quality of currency keeps it in circulation and prolongs its usage even though
government has dumped it..
Networking problem help Consider the following TCP session between h.pdf
Networking problem help Consider the following TCP session between hosts A and host B on a
perfect channel: A has a file of size 2.5MSS to send to B. A desires to send segments of
alternating sizes MSS and MSS/2 (sequence number = 0 for the first segment of size MSS). B
also has a file of size 2.5MSS to send to A. B desires to send segments of alternating sizes
MSS/2 and MSS (sequence number = 0 for the first segment of size MSS/2).
A sends first.Note, A and B don’t have to fully fill up their “desired” segment size if there is no
sufficient bytes to send, especially at the end of their conversation, where it is even possible for
them to send a segment whose data size is equal to 0. Draw all the segment exchanges until the
Both A and B think they don’t have any more bytes to send and there is no byte to acknowledge.
For each segment, clearly mark the sequence number, the ACK number, and the size of data it
carries. If the data size is equal to 0 in a segment, the sequence number field is irrelevant. You
may just mark N/A.
Solution
Source port: 16 Bit number which identifies the Source Port number (Sending Computer\'s TCP
Port).
Destination port: 16 Bit number which identifies the Destination Port number (Receiving Port).
Sequence number: 32 Bit number used for byte level numbering of TCP segments. If you are
using TCP, each byte of data is assigned a sequence number. If SYN flag is set (during the initial
three way handshake connection initiation), then this is the initial sequence number. The
sequence number of the actual first data byte will then be this sequence number plus 1. For
example, let the first byte of data by a device in a particular TCP header will have its sequence
number in this field 50000. If this packet has 500 bytes of data in it, then the next packet sent by
this device will have the sequence number of 50000 + 500 + 1 = 50501.
Acknowledgment Number: 32 Bit number field which indicates the next sequence number that
the sending device is expecting from the other device.
Header Length: 4 Bit field which shows the number of 32 Bit words in the header. Also known
as the Data Offset field. The minimum size header is 5 words (binary pattern is 0101).
Reserved: Always set to 0 (Size 6 bits).
Control Bit Flags: We have seen before that TCP is a Connection Oriented Protocol. The
meaning of Connection Oriented Protocol is that, before any data can be transmitted, a reliable
connection must be obtained and acknowledged. Control Bits govern the entire process of
connection establishment, data transmissions and connection termination. The control bits are
listed as follows: They are:
URG: Urgent Pointer.
ACK: Acknowledgement.
PSH: This flag means Push function. Using this flag, TCP allows a sending application to
specify that the data must be pushed immediately. When an application requests the TCP to push
data, the TCP should send the data that has accumulated without waiting to fill the segment.
RST: Reset the connection. The RST bit.
Lipid bilayers can only be synthesized by biological organisms. This .pdf
Lipid bilayers, which form cell membranes, can only be synthesized by biological organisms. It is believed that the internal compartments of eukaryotic cells, like organelles, developed from invaginations of the external prokaryotic cell membrane. Abiogenesis hypothesizes that life exists throughout the universe and was distributed to Earth via meteorites and asteroids, bringing extremophile bacteria trapped in debris. However, abiogenesis proposes that life arose from non-living organic compounds on Earth, not bacteria from space.
Is a neutral trait (meaning it is neither deleterious nor advantageo.pdf
Is a neutral trait (meaning it is neither deleterious nor advantageous to the survival and
reproduction of the organism) likely to be eliminated from a population by adaptive evolution?
(such as the presence of pelvic bones in snakes, which are legless) Why or why not?
Solution
There are four major methods by which evolution happens:
mutation, migration, drift, and selection
Mutation brings about changes or variations in the populaton.
Migration increases or decreases the number of the population.
Drift: when the individuals do not reproduce or they die, there could be disappearance of genes
which changes the frequency of occurrence of some genotypes in a population.
Selection occurs when the superior, better traits are selected to move forward in the generations.
When we consider evolution of neutral traits, we cover all the first three : Mutation, migration
and drift. These neutral traits generally stay in the population for a long time. They may
disappear eventually but its longevity is uncertain. It also could be that the genes responsible for
the neutral trait do not come under direct selection or it could also be the result of plieotropy
where one gene is responsible for many traits..
Let T R^n rightarrow R^m be a linear transformation. Given a subspa.pdf
Let T : R^n rightarrow R^m be a linear transformation. Given a subspace Z of R^m, let 5 {v
elementof R^n | T(v) elementof Z). Show that S is a subspace of R^n.
Solution
Let v,w in S
Then T(v) and T(w) belongs to Z
Consider av+bw , a,b are scalars
We need to see if av+bw are in S
For this consider T(av+bw) = aT(v)+bT(w) (because T is linear transformtaion)
Now T(v) and T(w) are in Z
And so aT(v) and bT(w) are in Z
This => aT(v)+bT(w) are in Z
Hence we get that T(av+bw) is in Z
So we get av+bw is in S
Hence S is subspace of Rn.
Just a general question on some vocab words I cannot piece together .pdf
Just a general question on some vocab words I cannot piece together myself. Can you provide
me with some relevance to some terms used in my biology class literature that I do not
understand.
Oxidized/oxidation. I understand what these are, but I do not understand their relevance... When
you oxidize a compound like ammonia NH3 to NO3...what is the point? does it make energy... is
it like an enzyme.. like what does that mean?
electron donor/acceptor....why does this matter which is which....? what is the purpose of this
besides donating and excepting electrons....?
NAD, NADPH... okay I know what these are composed of but what are they exactly and what is
their purpose...?
some of my definitions say things like \"use CO2\" as main carbon source\" ???? okay.. but what
does carbon have to do with anything... how is that energy or food or whatever?
Solution
1. ANS:
Oxidation: Oxidation is defined as the loss of electrons, hydrogen’s or gain of oxygen atom. If
the oxidation taken placed in a cell, then it is called as oxidized. Both the Oxidized/oxidation are
same, but the using situation is different.
Reduction: Reduction is defined as gain of electrons, hydrogen’s or loss of oxygen atom.
Depends upon reaction the redox (oxidation or reduction) will change, sometimes it explains
about electrons or in another time it states about oxygen but the sole of the meaning will never
change.
Ex: Oxidation and Reduction in terms of oxygen transfer
Oxidation and Reduction in terms of electrons transfer
Oxidation and Reduction in terms of hydrogen transfer
2. ANS: Nitrogen oxidation:
It is a process of biological oxidation, in which the anaerobic ammonia (NH4+) and nitrite
(NO2-) converts into nitrogen gas (N2).
Ammonia is converted into nitrite (NO2-) due to the effect of nitrosomonas bacteria. Nitrite
(NO2-) then is converted into nitrate (NO3-) by the influence of nitrobacter bacteria.
In this reaction ATP is not released, so the energy is not produced.
3. ANS: Electron donor/acceptor:
Electron acceptor: It accept ions that act as oxidizing agents in chemical reactions.
Electron donor: It donates electrons, these are reducing agents.
The main purpose of this donating and accepting electrons to stabilizes chemical reactions. In
biological point of view a series of electron transfer can produce ATP molecules. ATP act like a
universal currency. ATP is produced by photon gradient, which is created by ETC in
mitochondria.
4. ANS: NAD and NADPH:
NAD is a primary oxidizing agents of cell and the NADPH is a primary reducing agents of cell.
NAD in oxidation reactions, it accepts two electrons and one photon from the substrate.
In reduced form NADPH acts as the primary reducing agent of cell, it donates two electrons and
one photon to the medium.
5. ANS:
In the photosynthesis reactions plants make glucose by incorporating CO2 and water. The
glucose molecule later oxidized in organisms and produced energy in the form of ATP. Foods
are mostly composed with carbohydrates.

In about six billion years, our suns luminosity (a.k.a. power outpu.pdf
In about six billion years, our sun\'s luminosity (a.k.a. power output) will be 2000 times more
than it is now. At this stage, our sun will be considered a \"red giant\" star. The surface
temperature of a red giant is only about two thirds of our sun\'s current temperature. Between
what two famous celestials objects will be the location of our sun\'s surface in six billion years?
Solution
Luminosity,L = k*R^2 * T^4
so, L2/L1 = [R2/R1]^2 * [T2/T1]^4
2000 = [R2/R1]^2 * 0.1975
R2 = 100.62 * R1 = 100.62 * 6.96*10^8 = 7.003 * 10 ^10m
Radius of orbit of mercury = 4.6*10^10 m - 7 * 10 ^ 7m
Radius of orbit of venus = 1.08*10^11 m
Hence sun\'s surface will be between venus amd mercury.

Fill in the blanks.Intensity of orangebrownred color of reduced .pdf
Fill in the blanks.
Intensity of orange/brown/red color of reduced DNS is ____________ related to the amount of
_______________ in solution.
Solution
Intensity of orange/brown/red color of reduced DNS is proportionally related to the amount of
maltose in solution.
DNS is used to study the enzymatic activity of amylase, which breaks starch into maltose.
Higher amylase activity produces more amount of maltose, which reduces 3, 5-dinitrosalicylic
acid (DNS), which is yellow in color, to 3-amino, 5-nitrosalicylic acid (commonly termed
\"reduced DNS\"), which may be orange, brown or red depending on the concentration of
maltose..
Explain how cellular respiration (O2 consumption and CO2 production).pdf
Explain how cellular respiration (O2 consumption and CO2 production) is linked to ATP
production. Is the coupling of these two processes perfect? Why or why not?
Solution
The primary function of cellular respiration is to generate ATP, which traps some of the
chemical energy of food molecules in its high- energy bonds (adenosine triphosphate). The
process of generation of ATP is via glycolysis and Krebs’s cycle finally through oxidative
phosphorylation.
The overall balanced reaction of cellular respiration is:
CHO + 6O 6CO + 6HO + ATP
Glucose + oxygen carbon dioxide + water + energy
In this reaction, glucose oxidized and oxygen reduced.
Cellular respiration (O2 consumption and CO2 production) is linked to ATP production because
it is different from cellular respiration as it involves metabolic activities using molecular oxygen
such as Citric acid cycle and electron transport to synthesize energy in the form of ATP to
perform respiration. CO2 is the output of the cellular respiration from mitochondria and expelled
out of the body by carrying through hemoglobin in the form of carboxy- hemoglobin to the
alveoli of lungs.
The coupling of these two processes such as O2 consumption and CO2 production inked to ATP
production is perfect. Mitochondrial chemiosmosis –cellular respiration (through Fernadez
Moran inner mitochondrial oxysomes particles) during cellular respiration obtain energy from
chemical enzymatic breakdown of the organic food molecules (glucose, pyruvate, acetylcoA) to
produce ATP in the presence of O2 consumption. During electron transport, the final electron
acceptor is oxygen for oxidative phosphorylation via energy producing molecules such as NADH
(3 ATP), FADH2 (2ATP) and ATP. Therefore, it is going to \"oxygen\" that accepting electrons
at the end of the electron transport chain to generate ATP via mitochondrial respiratory complex-
I to V. Every 3 protons used to produce one ATP molecule. Inner membrane possess small
protein channels known as porins in mitochondria & these channels promote the movement of
any small molecules such as ATP through them
However, the coupling is perfect between the O2 consumption and CO2 production for ATP
production but whole-organism oxygen consumption is mainly related to rate of substrate
oxidation & it cannot be accurate measurement for ATP production due to variable P/O ratio
occurs..

Entrepreneurship is
A. one of the basic rights of the private enterprise system.
B. the willingness to take risks.
C. required for capital expansion.
D. not found in the private enterprise system.
Solution
B. the willingness to take risks.
entrepenuership is the willingness to take risk. even if u have money and idea of business, but u
don\'t have willpower to invest in that idea and take risk than u can\'t be entrepreneure. so risk
taker can only become entrepenure than only he can set up a business by using his own or
borrowed capital..
Discrete Random Variables we are working with commonly used discre.pdf
Discrete Random Variables
we are working with commonly used discrete and continuous distribution In a hospital there are
16 patients, 4 of whom have AIDS. A doctor is assigned to 6 of these patients at random. What is
the probability that he gets 2 of the AIDS patients?
Solution
There are 16C6 ways to choose any 6 patients.
There are 4C2 ways to get 2 with AIDS, and 12C4 to choose 4 without.
Thus,
P = [(12C4)(4C2)]/(16C6) = 0.370879121 [ANSWER].

Discuss and define Isotropy. Anisotropy and Orthotropy with regards t.pdf
Discuss and define Isotropy. Anisotropy and Orthotropy with regards to engineering materials.
Regarding Finite Element Analysis: List the three main types of elements and explain how to
choose elements? Common sources of errors in FEA? After conducting a photoelastic
investigation of a sample, you remove the load and notice that a fringe pattern still exists. What
could this mean?
Solution
(i)
Isotropy is the property of the material in which the physical properties of a substance are
independent of the direction of measurement. Glass and metals are examples of isotropic
materials.
Anisotropy is the property of the material in which the physical properties of a substance varies
with the change in direction. Wood and Composites are examples of anisotropic materials.
Orthotropy is the property of the material in which the physical properties of a substance change
when measured from different directions. The properties differ along three mutually orthogonal
twofold axes of rotational symmetry. Wood is an example of orthotropic materials.
(ii)
(a )The three main elements in FEA are -.
Consider the circuits in figure 2.32. If we assume the transistors ar.pdf
Consider the circuits in figure 2.32. If we assume the transistors are well described by the
Schockley model and their respective S and B terminals are tied together, the two circuits are
equivalent (i.e. I_dsi=I_ds2). If the body effect is considered, will I_Ds2 be equal to, greater
than, or less than I_dsi? Consider only body effect: assume velocity saturation and mobility
degradation effects are negligible. Explain.
Solution
As source(S) and Substrate terminals are tied together, hence VSB= potential difference between
S and B=0.
Hence is no body effect.
Hence Id1= Id2..

To this date, we have only been able to develop non-living protobio.pdf
- 1. To this date, we have only been able to develop non-living protobionts in the lab, and nothing else beyond this point. True False Montmorillonite clay is important in that it is thought to have facilitated the process of abiogenesis by expediting/facilitating the formation of complex self-replicating molecules, and the generation of phospolipid bilayers that might have assembled into the first cell membranes. True False One of the limitations of the current fossil record in our planet is that it is biased in favor of the species that have left hard bony structures and/or had lived for a long periods of time. True False Tappania plana, an example of the first unicellular prokaryotes, is thought to be an alga or a fungus. True False Early in 2017 scientists have discovered a new family of eukaryotic bacteria in the thermal vents of Iceland. These eubacteria - named Locky and Aasgard after the Nordic Viking gods-are thought to be the source of all eukaryotic cells in the planet. True False Solution 37: FALSE: Protobionts are the aggregrates of organic polymers that are supposed to be spontaneously formed under certain conditions through chemical evolution. To this date, the living protobionts have been synthesized in the lab which exhibit all the properties of living cell except using DNA to program the protein synthesis.
