AUTOTROPHS & HETEROTROPHS
Autotrophs make their own food using energy they get directly from the environment, and carbon from inorganic sources such as CO
2
. By metabolic pathways of photosynthesis, plants and other autotrophs capture the energy of light and use it to build sugars from water and carbon dioxide. Heterotrophs get energy and carbon molecules from molecules that other organisms have already assembled.
Earth's early atmosphere held very little free oxygen, and chemoautotrophs were common. When the noncyclic pathway of photosynthesis evolved, oxygen released by photoautotrophs permanently changed the atmosphere, and it was a selective force that favored evolution of aerobic respiration. Photoautotrophs remove CO
2
from the atmosphere; the metabolic activity of most organisms puts it back. Human activities disrupt this cycle by adding extra CO
2
to the atmosphere. The resulting imbalance is contributing to global warming.
Can you do some additional research and find at least one specific heterotroph?

THE EVOLUTION OF PHOTOSYNTHESIS
Life theoretically originated on Earth 3.4 to 4 billion years ago. The atmosphere was thin: composed of methane, carbon dioxide, and water vapor. Any gaseous oxygen had been used up in the combustion (or oxidation) of materials when the Earth was very hot.
The cooling water collected in pools, assimilating nutrients from the rocks. As water evaporated, the nutrients concentrated, forming a rich soup. The first organisms would have lived well off this food source, breaking down the complex molecules into water and carbon dioxide through respiration. Eventually, as life grew, the need arose to somehow re-synthesize complex compounds, both to eat and to use for structure and function. Some organisms learned how to use the Sun's energy to synthesize large molecules from small molecules. Other organisms learned to use other sources of reductive power. These organisms that have learned how to build the building blocks of life are called autotrophs, or self-feeders. Autotrophs are found in the bacterial and plant

This practice worksheet will have you spending time thinking about Cy.pdf
This practice worksheet will have you spending time thinking about Cyanobacteria and some
fellow photosynthesizers. 1. Had this been the year 2013, I would have taught you that all extant
Cyanobacteria are capable of oxygenic photosynthesis. I also would have taught you that some
of the earliest fossils of life on earth are stromatolites, which are beach-ball-sized structures
believed to have been formed by ancient Cyanobacteria 3.5 billion years ago. In 2013, I would
have put these two facts together and taught you that oxygenic photosynthesis must have been
present by 3.5 bilion years ago and that the Great Oxidation Event, which occurred 2.4 billion
years ago when O2 from oxygenic photosynthesis started to accumulate in the atmosphere and
oceans, was simply a long time ( 1 billion years) in the making. However, in the last ten years we
have discovered two lineages of Cyanobacteria that, much to our surprise, proved to be non-
photosynthetic. The phylogenetic relationship of these two new lineages (seen in the image
below) has forced us to reinterpret the timing of the origin of oxygenic photosynthesis. First,
explain why the fossils and phylogeny combine to make us think that oxygenic photosynthesis
might not be as ancient as we once thought. And second, why would a different pattern of
phylogenetic relationship-for example, if these two new lineages had been nested inside of the
clade of previously known cyanobacteria-not have caused us to reconsider our earlier thinking?
2. C4 photosynthesis is a "carbon-concentrating mechanism" found in a variety of plants, most
notably in the grasses. First, briefly explain why some plants would need a carbonconcentrating
mechanism. Why wasn't the traditional version of photosynthesis (known as C3 photosynthesis)
good enough, and what is it that plants are compensating for? And second, briefly explain why
the phylogenetic distribution of C4 photosynthesis (shown in red in the figure below) supports
the claim that C4 photosynthesis is an adaptation. Why, for example, would a single clade of all
those C4 photosynthesizers fail to provide as strong support for the claim? 3. We can trace
ancestry all the way back to LUCA (i.e., the last universal common ancestor, from 3.5 billion
years ago) from present-day eukaryotic algae. We don't think LUCA was an oxygenic
photosynthesizer, nor do we think it was an aerobic respirer. But the algae are both of these.
Three questions here: 1 .) in what order (photosynthesis then respiration, or vice versa)..; 2.)
when (+/1020% is close enough, given our current uncertainty about timing)..; and 3 .) how ...did
the eukaryotic algal lineage come by these two metabolic capabilities?
4. As we've discussed, some of the so-called "major transitions in evolution" represent the
creation of new kinds of individuals (e.8., the origin of eukaryotes, the origin of multicellular
organisms, the origin of animal societies). Among these, some represent the coming together of
unrelated or.

Bats rely on sound localization to be able to fly during the night. O.pdf
Bats rely on sound localization to be able to fly during the night. On a cool 20 degree C summer
night, a bat produces an ultrasonic sound with a frequency of 37 kHz. What is the wavelength of
this ultrasound, in meters? While remaining stationary, the bat emits a sound pulse and receives
an echo after 0.130 s. How far away, in meters, is the reflecting object from the bat?
Solution
1) wave length of ultra sound waves = velocity / frequency
= 330/37kHz ( velocity of ultra sound waves in air = 330 m/sec)
=.00089189m
2) time taken = .130
distance travelled for the sound pulse = 2*d ( because it is also returing back after strucking the
object)
v*t=2*d
d= 330*.130/2=21.45m.
A layer of dirt must be spread over a circular area 13.5 feet in dia.pdf
A layer of dirt must be spread over a circular area 13.5 feet in diameter. How deep a layer will be
obtained using 75 cubic feet of dirt? Round to the nearest tenth.
Solution
Dirt deposit would form a cylider of 75 cubic feet of volume
Volume = pi(r^2)*h
r = 13.5 feet
75 = pi(13.5)^2 *h
where h is depth of dirt
h =0.13 = 0.1 feet.

Discuss the impact that the tonnage of sulfur or sulfuric acid recov.pdf
Discuss the impact that the tonnage of sulfur or sulfuric acid recovered from SO2 in flue gas
treatment would have upon the chemical industry if all coal- and oil-fired were required to use
such treatment processes.
Solution
YEs, definitely we must required to use FGD as sulfur dioxide enters the air mainly from
industrial processes and from the combustion of hydrocarbon fuels with a substantial sulfur (S)
content and represents a major source of air pollution. Sulfur dioxide is a colorless, corrosive gas
that has a bitter taste, but no smell at low levels. The share of SO2 emissions comes from the use
of coal and oil in fossil-fired power plants, in industrial combustion units, in small combustion
units in households, and in vehicles. Besides the concentration of SO2 in stack gases emitted by
steam generation plants is usually in the range of 800 to 6000 mg/Nm3, the volume of gases
produced by the utility industry worldwide results in the liberation of a large tonnage of sulfur
dioxide into the atmosphere.Sulfur dioxide is a chemical that can be dangerous in many ways. At
lower levels, sulfur dioxide has been found to be a corrosive irritant to eyes and skin. Sulfur
dioxide has been associated with a variety of respiratory diseases and increased mortality rates.
Inhalation of sulfur dioxide can cause increased airway resistance by constricting lung passages.
Sulfur dioxide is also one of the main ingredients in acid rain. Acid rain occurs when sulfur
dioxide or other gaseous chemicals, such as nitrogen oxides, are released into the air. These
gases ascend through the atmosphere, and when they reach upper cloud levels, they react with
water, oxygen, and sunlight.Various concentrations of sulfuric acid and nitric acid are then
produced. These acids mix with the condensed water vapor in the clouds and fall to the ground
with the water in various forms of precipitation. This precipitation with greater acidity is what is
known as acid rain. Acid rain is dangerous to many natural ecosystems; it can harm plants, sand,
make water undrinkable, and unlivable for many animals. The biggest producers of sulfur
dioxide emissions are electrical utilities that produce electricity through the burning of fossil
fuels.Sulfur dioxide emissions, from combustion installations using coal or HFO, can be reduced
by fuel desulfurization or by FGD, as well as by a combination of these two measures.
Flue gas desulfurization is an efficient method for the reduction of the sulfur dioxide emissions.2
Many processes are available in the market, such as (a) wet scrubbers, (b) spray dry scrubbers,
(c) sorbent injection, (d) regenerable processes, and (e) combined SO2/NOX removal processes.
You have decided to go to graduate school for Molecular Biology (yay!.pdf
You have decided to go to graduate school for Molecular Biology (yay!). Your first project
involves investigating the regulation of expression of a gene suspected to be involved in the
immune response to Zika Virus (we\'ll call this gene ZV1). You have found that this gene is
expressed when someone is infected by Zika, but is not expressed in uninfected people. You
believe that this is due to a change in a histone modification. Come up with a hypothesis for
what type of change in histone modification may be responsible for the expression of this gene
upon infection with Zika. Describe, in detail, an experiment to test your hypothesis. Include any
necessary controls. Assuming your hypothesis is correct (of course it is), draw the results of the
experiment (it doesn\'t have to be perfect, do the best you can). One of your friends in graduate
school is super interested in your project. She thinks that there may be an epigenetic component
to the expression of this gene in response to Zika Virus other than that of histone modifications.
Describe a non-chromatin based mechanism for this and briefly describe how you might test this.
Solution
Thanks for the question.
a. A hypothesis for the mechanism of expression of gene following infection with zika virus is
follows
the zika virus upon entering the body produces a translation whereby a RNA genome is produced
which enters the endosomal membrane of the host cell causing the symptoms of zika virus fever
etc
b. an elisa test (enzyme linked immuno sorbent assay) which could test either the zika virus or its
translated RNA could be a good way of assessing the infection of zika virus.
c. A standard can be set up on the number of zika virus or its replicated RNA which is necessary
to be present in the body of the infected patient to call him to be actively infected with the virus.
This will decide for subsequent patients if they are infected with the virus and also if they are
actively carrying the infection.
d. the original hypothesis stated above is already having an epigenetic component. Hence its
detection and other procedures are already mentioned above.

We have to use the follwing line in HTML
Also we have to ensure the myprint.css is printer friendly. For example,
we should not display ant href tag in print format. So hide all the links and so on..
Why was any carbon-containing molecule originally called organic.pdf
Why was any carbon-containing molecule originally called \"organic\"? A. Carbon-containing
molecules were thought to be only produced by organisms. B. Carbon-containing molecules
contain organic substances within them that cannot be synthesized inorganically. C. Carbon-
containing molecules do not contain hydrogen or oxygen, the inorganic parts of organisms. D.
Carbon-containing molecules were thought to be present only outside of organisms - in the
inorganic areas of the earth: water, air, and stone.
Solution
Correct answer (A)
It was once thought that organic compounds could only be created by living organisms..
Which of the following is true about indexes and index design a. in.pdf
Which of the following is true about indexes and index design? a. indexes usually speed up
write operations b. a composite index is an index on a single column c. indexes should be
created on columns used by WHERE and BY clauses d. an index is created for every foreign
key by default
Solution
Answer: Indexes should be created on columns used by WHERE and BY clauses.
Indexes are used for retrieve the records fast. So we have to mention the column names in
WHERE clause and By clause in which we created the columns for fast retrieval of the records..

What is the between facial action unit and facial landmark differenc.pdf
What is the between facial action unit and facial landmark differences ?
Solution
There is a difference between the facial action unit and facial landmark.
The difference can be illustrated as follows:
FACIAL ACTION UNIT:
Humans interact far more naturally with each other tahn they do with machines. To approach the
naturalness of face-to-face human interaction machines should be able to emulate the way
humans communicate with each other. Although speech alone is often sufficient for
communicating with another person, non-verbal communicative cues can help to synchronize the
dialogue, to signal comprehensionor disagreement and to let the dialogue run smoother, with less
interruptions. With facial expresssions we clarify what is said by means of lip-reading, we stress
the importance of the spoken message by means of conversational signals like raisisng eyebrows,
and siognal comprehension,disagrreement,boredom and intensions.
Machine understanding of facial expressions could revolutionize user interfaces including
ambient,automotiveand robot interfaces and has become,therefore,a hot topic in computer-vision
approach.
FACIAL LANDMARK:
Localizing facial landmarks (i.e facial alignment) is a fundamental step in facial image analysis.
However, the problem is still challenging due to the large variability in pose and appearence, and
the existence of occlusions in real-world face images.
EGM (Exemplar-based graph matching) framework is used in the facial landmark
localization.Compared to conventional algorithms, EGM has three advantages:.

Valinomycin is a potassium ionophore. What would be its effect on in.pdf
Valinomycin is a potassium ionophore. What would be its effect on insulin secretion by cells
that were exposed to valinomycin?
Solution
Ionosphore are the molecules which can transfer a particular ions across a semi-permeambke
membrane..!! Valinomycin is also a ionophore which transfer the potassium across the cell
memberane..
Due to which when it is exposed to the beta cells of insulin it inhibits the secretion of insulin in
the body as potassium plays a major role in insulin secretion.. As the concentration of potassium
is disturbed in the beta cells in inhibits the insulin secretion.. Hence the blood glucose level
increases..!!.
The retrovirus genome is made of the nucleic acid before the virus be.pdf
The retrovirus genome is made of the nucleic acid before the virus becomes a provirus, in order
for that to occur the form of the genome must be converted to
Solution
1) Answer:
The retrovirus genome is made of the nucleic acid, RNA before the virus become a provirus; in
order that to occur, single stranded form of the genome must be converted to double stranded
form.
Explanation: A retrovirus is a single-stranded RNA virus with a DNA intermediate and, as an
obligate parasite, targets a host cell. In most viruses, DNA is transcribed into RNA, and then
RNA is translated into protein. However, retroviruses function differently, as their RNA is
reverse-transcribed into DNA (by an enzyme reverse transcriptase), which is integrated into the
host cell\'s genome (when it becomes a provirus), and then undergoes the usual transcription and
translational processes to express the genes carried by the virus.
2) Answer:
Human make RNA during a process called transcription.
Synthesis of RNA is usually catalyzed by an enzyme—RNA polymerase—using DNA as a
template, a process known as transcription..
the probability that it is raining is .25. the orbability that it is.pdf
the probability that it is raining is .25. the orbability that it is windy is .30. if it is windy, the
probability that it is raining is .40. what is the probabilty that it is raining and windy? assume that
the events raining and windy are not independent.
Solution
Let R denote the event of raining and W that of winding.
Given, P(R)=.25
P(W)=.3
and P(R|W) = .4
We know P(R|W) = P(RW) /P(W)
=> P(RW) = P(R|W)*P(W)
=>P(RW)=P(It is raining and windy)=(.4)*(.3)=0.12.

Significance of Discoveries in Genetics and DNA Our understandin.pdf
Significance of Discoveries in Genetics and DNA
Our understanding of genetic inheritance and the function of DNA in producing the
characteristics of the individual have been developing for more than 150 years.
Consider our current state of knowledge.
Link genetic characteristics to DNA structure.
Explain how DNA through the process of protein synthesis is responsible for the ultimate
expression of the characteristics in the organism.
Describe how interference in protein synthesis can result in disruption of cellular and bodily
processes?
How does the significance of one class of proteins, the enzymes, relate?
Please answer all questions!
Solution
1. Genes are segments of chromosome and correspond to DNA sequence(s). The DNA segment
carries coded information for the synthesis of specific proteins which carry out different
functions in the cell. The characters are expressed through proteins.
DNA is packed into chromosomes. In gametes, the chromosome number is halved. The fusion of
gametes in zygotes restores the chromosome number.
2. Segments of DNA called genes carry traits in encoded form. The genes undergo transcription
(transfer of information from DNA to RNA). This is followed by translation which is the transfer
of information from the RNA to the protein. The characters are expressed through proteins which
are specific in function.
3. Various antimicrobial drugs interfere with the process of protein synthesis at the ribosome
level. The information encoded in the nucleotides of DNA are expressed through proteins which
carry out specific functions in the cell. Disruption of protein synthesis prevents the biochemical
pathways and specific functions of proteins.
4. Enzymes are responsible for controlling various vital activities in the cell. They synthesize,
deliver and eliminate various chemicals. Enzymes undergo slow depletion which reduces overall
strength and viatality of the human body..
Scope is much less complicated if functions cannot contain other func.pdf
Scope is much less complicated if functions cannot contain other function definitions (C++,
Java: cannot; Ada, Pascal, Ada, Python, Ruby, Lisp: can). Give one good reason why functions
should not contain other function definitions. Give one good reason why it should be allowed.
Solution
A function is the smallest block of code to perform a specific task. Which can be independently
invoked.
The variable defined in a function are available only to that block not to the whole program
which gives abstraction.
the scope and life of variable defined in the funciton are available only when it is invoked, which
saves memory as well.
b.
To keep a function isolated. It\'s only used inside the function which is invoked i.e. one place.
when it\'s locally used why define globally.It\'s just another way of breaking down a big function
into smaller pieces without affecting the global namespace with another function name. Quite
often the inner function isn\'t a stand-alone so doesn\'t rightfully belong in the global namespace..

Refer to the drawings in Figure 13.2 of a single pair of homologous chromosomes as they might
appear during various stages of either mitosis or meiosis, and answer the following questions
(28). Which diagram represents chromosomes in prophase I of meiosis? I II III IV V VI
Which diagram represents anaphase II of meiosis? I III IV V
Solution
26) IV
Explanation: During prophase I of meiosis, synapsed homologous chromosomes are observed as
tetrads.
27) II
Explanation: There is separation of centromeres. As a result, chromatids separate and they are
now called independent chromosomes..
Prions are viruses that cause proteins to misfold. Select one True.pdf
Prions are viruses that cause proteins to misfold. Select one: True False
Solution
12). FALSE
Prion is an infectious agent completely made of a protein known as PrP, they are not viruses.
Prions can fold in multiple ways to form different 3-D structures (means tertiary structure),
which makes them resistant to many of the sterilization processes such as heat, UV light,
formaldehyde and also resistant to proteases. Priones do not contain genetic material or capsid..

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
