Plant cell
Robert Hooke discovered cells in 1665 using an early microscope. He observed the structures of cork cells. The development of electron microscopes in the 1930s allowed scientists to view cells and organelles at much higher magnifications. Key discoveries included the nucleus by Brown in 1831, living cells by Van Leeuwenhoek in 1674, and the proposal of the cell theory by Schleiden, Schwann, and Virchow from 1838-1858 stating that cells are the fundamental unit of life. Plant cells have additional structures like a cell wall and chloroplasts. The main components of plant cells are the cell membrane, cytoplasm, and nucleus. The nucleus contains DNA and controls the cell.

DNA and its DISCOVERY.pdf
DNA
its Discovery
Who Discovered DNA?
Credit for who first identified DNA is often mistakenly given to James Watson and Francis Crick, who just furthered Miescher’s discovery with their own groundbreaking research nearly 100 years later. Watson and Crick contributed largely to our understanding of DNA in terms of genetic inheritance, but much like Miescher, long before their work, others also made great advancements in and contributions to the field.
In 1866, before many significant discoveries and findings, Gregor Mendel was the first to suggest that characteristics are passed down from generation to generation. Mendel coined the terms as recessive and dominant.
In 1869, Friedrich Miescher identified the “nuclein” by isolating a molecule from a cell nucleus that would later become known as DNA.
In 1881, Nobel Prize winner and German biochemist Albrecht Kossel, who is credited with naming DNA, identified nuclein as a nucleic acid. He also isolated those five nitrogen bases that are now considered to be the basic building blocks of DNA and RNA: adenine (A), cytosine (C), guanine (G), thymine (T) and uracil (U) in case of RNA).
In 1882, Walther Fleming devoted research and time to cytology, which is the study of chromosomes. He discovered mitosis in 1882 when he was the first biologist to execute a wholly systematic study of the division of chromosomes. His observations that chromosomes double is significant to the later discovered theory of inheritance.
In Early 1900s, Theodor Boveri and Walter Sutton were independently working on what’s now known as the Boveri-Sutton chromosome theory, or the chromosomal theory of inheritance. Their findings are fundamental in our understanding of how chromosomes carry genetic material and pass it down from one generation to the next.
In 1902, Mendel’s theories were finally associated with a human disease by Sir Archibald Edward Garrod, who published the first findings from a study on recessive inheritance in human beings in 1902. Garrod opened the door for our understanding of genetic disorders resulting from errors in chemical pathways in the body.
In 1944, Oswald Avery first outlined DNA as the transforming principle, which essentially means that DNA transform cell properties.

Phy 301 a | Project Report
Mitochondria are double-membrane organelles found in animal and plant cells that produce energy through oxidative phosphorylation. They contain their own DNA and are inherited maternally. A 1987 study traced human mitochondrial DNA back to a single female ancestor, termed mitochondrial Eve, who likely lived around 200,000 years ago in Africa. Mitochondria have a variety of functions including energy production, calcium regulation, hormone and blood cell component synthesis, and apoptosis. They originated through endosymbiosis when a bacterium was engulfed by a host cell and evolved to perform essential metabolic functions.
Nanotechnology-1.docx
This document discusses nanotechnology and nanophysics. It defines nanoscience as the study of structures between 1-100 nm, known as nanostructures. There are two main techniques for synthesizing nanomaterials: bottom-up and top-down. Bottom-up techniques build materials atom by atom through methods like molecular self-assembly and positional assembly. Nanophysics studies how materials behave differently at the nanoscale due to changes in internal structure and properties governed by quantum mechanics rather than classical physics. Nanotechnology involves manipulating individual atoms and molecules to produce new materials with novel properties.

Phy 301 a Presentation
Mitochondria are organelles found in eukaryotic cells that produce energy through cellular respiration. There are two main theories about their origin - either through the engulfment of an aerobic prokaryote by an anaerobic host cell or by an archaebacterial host cell. Mitochondria have their own DNA and unique structures like the inner and outer membranes that allow them to carry out functions like ATP production. They also play roles in processes like apoptosis and calcium ion storage. Mitochondrial DNA is only inherited maternally and can be used to trace human maternal ancestry back to Mitochondrial Eve around 200,000 years ago in Africa.

This document discusses nanotechnology and nanophysics. It defines nanoscience as the study of structures between 1-100 nm, known as nanostructures. There are two main techniques for synthesizing nanomaterials: bottom-up and top-down. Bottom-up techniques build materials atom by atom through methods like molecular self-assembly and positional assembly. Nanophysics studies how materials behave differently at the nanoscale due to changes in internal structure and properties governed by quantum mechanics rather than classical physics. Nanotechnology involves manipulating individual atoms and molecules to produce new materials with novel properties.

Phy 301 a Presentation
Mitochondria are organelles found in eukaryotic cells that produce energy through cellular respiration. There are two main theories about their origin - either through the engulfment of an aerobic prokaryote by an anaerobic host cell or by an archaebacterial host cell. Mitochondria have their own DNA and unique structures like the inner and outer membranes that allow them to carry out functions like ATP production. They also play roles in processes like apoptosis and calcium ion storage. Mitochondrial DNA is only inherited maternally and can be used to trace human maternal ancestry back to Mitochondrial Eve around 200,000 years ago in Africa.
BIOLOGY 2 CHAPTER NOTES by N.AZAM RAHIMOON
1. The document discusses the history and key discoveries that led to the cell theory, including Hooke's discovery of cells in 1665 and the formulation of the cell theory by Schleiden and Schwann in 1838-1839.
2. It then covers the development of microscopy technologies like the light microscope and electron microscope, which allowed for greater magnification and resolution of cellular structures.
3. The main components of the eukaryotic cell are described, including the cell membrane, nucleus, cytoplasm, mitochondria, Golgi bodies, endoplasmic reticulum, ribosomes, and plastids. The functions of these structures are also summarized.
Nano Biotechnology
This document discusses nanobiotechnology and how it can be applied in medicine. It describes how nanotechnology allows us to understand and manipulate matter at the molecular level, and how this enables the development of novel biomedical applications like nanobiosensors, nanomedicine, and nanosubmarines for targeted drug delivery. Specific examples mentioned include using ribosomes as nanomemories, biochemical motors like ATPase for powering nanorobots, and developing new insights into DNA structure and function through nanotechnology. The overall message is that nanobiotechnology has great potential for advances in diagnosis, treatment, and understanding of biological processes at the cellular and molecular scale.

Answer:
e.none of the above (all are true statements)
Applicationsof DNA fingerprinting:
In criminal investigations, the DNA fingerprint of a suspect\'s blood or other body material is
compared to that of the evidence from the crime scene to see how closely they match. The
technique can also be used to establish paternity. Forensic dentistry plays an important role in
human identification in mass disasters, especially in fires, explosions, decomposing bodies or
skeletonized bodies, when there is little material remaining to perform visual identification.

AnsTriploidy is a desirable trait in all angiosperms except orchi.pdf
Ans:
Triploidy is a desirable trait in all angiosperms except orchidaceae and Triploidy could be a
desirable trait in agricultural species where the economic part especially fruits. Triploid hybrids
have one of the most important traits, seedlessness, which is the characteristic for the fresh-fruit
market. Triploid embryos are found in small seeds that do not germinate. Triploid plants raised
from endosperm are generally sterile. Endosperm-raised triploid plants are of commercial value,
e.g. timber-yielding plants, edible fruit plants or ornamentals propagated vegetatively and
multiplied mainly through micropropagation.
Triploid plants often show vigorous vegetative growth and in some species produce excellent
seedless fruit. All cultivated bananas are triplods, and must be propagated vegetatively as they
bear no seed. Some sugar beet varieties are triploid and these tend to be higher yielding than
diploid varieties. In some species it is not desirable as they produce little or no seed, each
generation of a triploid variety has to be made afresh by the hybridization of a diploid and a
tetraploid parent.
Eg: Commercial use of triploid fruits can be found in watermelons and are produced artificially
by first developing tetraploids whicg are then crossed with diploid watermelon. In order to set
fruit, the triploid watermelon crossed with desirable diploid pollen donar.
It is an undesirable trait
In some species it is not desirable as they produce little or no seed (may be sterile because they
cannot form gametes with a balanced assortment of chromosomes), each generation of a triploid
variety has to be made afresh by the hybridization of a diploid and a tetraploid parent.
Eg: Diana\' (1963, USA) has large single, pure white petals with crimped edges. It is a triploid,
so produces little or no viable seed, and thus continues to flower over a long period. It was
followed in the 1980s by more triploid cultivars, in particular \'Aphrodite\'
polyploidy leads to significant reduction in the amount of genetic diversity in some species. As
genetically identical clones, a pest or disease that affects one individual is likely capable of
affecting each of its clones. Eg: vast majority of commercially produced bananas are cloned from
a single source, the Cavendish cultivar, and those plants are currently threatened worldwide by a
newly discovered fungal disease to which they are highly susceptible.
It is an undesirable trait in crop species where the economic part is seed Example : Orchidacea
The Phalaenopsis species bear a very brightly colored and patterned flowers were reintroduced
into cultivation. Many of these novelty species however produce inflorescences with only a very
few, tiny, starry-shaped flowers. These diploid species have been crossed with the modern
autopolyploid white types to improve their size, form, and floriferousness. In many instances,
these characteristics were improved but flower color was substantially diluted. In addition, many

a) Rotenone is an isoflavone used as insecticide and pesticide. It works by interfering with
Electron transport chain in mitochondria. It inhibits the transfer of elctrons from Complex 1
toUbiquinone. It is mildly toxic to humans and other mammals. But highly toxic to fish and
insects because it is easily taken up through the gills or trachea but not through skin or
gastrointestinal tract. The inhibition of NADH dehydrogenase by Rotenone decreases the rate of
electron flow which inturn decreases the ATP production. If it does not meet ATP requirements
the organisms die.
b) Antimycin A binds to the Qi site of cytochrome reductase in the mitochondrial complex 3 and
inhibits the oxidation of Ubiquinol. It strongly inhibits the oxidation of reduced Q in the
respiratory chain severely limiting the rate of electron transfer and ATP production.
c) Rotenone inhibits electron flow through complex1 whereas Antimycin Ainhibits electron flow
through NAD linked complex 1 and also at complex 2 from succinate and fatty acyl coA through
FAD. So, Antimycin A is more potent poisonous.

A pivot table is a table which is used to store the summary of a cer.pdf
A pivot table is a table which is used to store the summary of a certain data set in a condensed
manner. The table consists of rows, columns, data fields, and pages. These components can be
moved around and it helps the user to expand, isolate, sum, and group the particular data in real
time. This table enables the user to view the differences in a very big set of information. It is
very helpful in organizing a large amount of data in Microsoft Excel.
Easy to Use and data analysis
An important advantage of pivot tables is that it is easy to use. You can easily summarize data by
dragging the columns to different sections of the table. The columns can also be re-arranged as
you wish with the click of a mouse.With the help of excel pivot tables, you can handle large
quantities of data in one single go. These tables allow you to take a large amount of data and
work on it in such a way that you need to view only a few data fields. This helps in the easy
analysis of large amount of data.
Working of the Table and Find Data Patterns
A pivot table takes a user-specified data field and converts the header of each column into a data
option which can be easily manipulated by the user. Columns containing data can be removed
from, added to, or moved around the table quite easily. Here, user friendly and informative
summaries can be created from long spreadsheets of raw data. The data can be summarized in
various ways including frequencies and averages. Using the pivot table in excel has many
benefits which are described below. Excel pivot tables help you to create customized tables from
large data groups. Manipulating data in this manner will help to find recurring patterns in the
data, if any. This in turn will help in accurate data forecast.
Easy Summary of Data with Quick Report Creation
Another important benefit of pivot tables is that it helps to summarize data in a quick and easy
manner. The table helps in making a concise summary out of thousands of rows and columns of
unorganized data. With the help of these tables you can summarize large amounts of information
into a small space. The data can be summarized in a simple format which is easily
understandable. Users can arrange rows and columns of the data according to their needs and
they can label it and sort it in any way they want to.One of the important features of excel pivot
tables is that it helps to create reports in an efficient way. This saves you the long and strenuous
hours that you need to spend for creating reports manually. Apart from this, the table also helps
you provide links to external sources if any, in the report created.
Helps in Quick Decision Making
A pivot table can be considered to be a valuable Excel reporting tool as it allows users to easily
analyze the data and arrive at quick decisions. This serves as a huge advantage in the industrial
world, where it is crucial to make precise and quick decisions.
Conclusion: By considering the advantages that the pivot table have it .

A group of isotopes representing various stages of radioactive decay.pdf
A group of isotopes representing various stages of radioactive decay in which the heavier
members of the group are transformed into successively lighter ones, the lightest being stable. In
nuclear science, the decay chain refers to the radioactive decay of different discrete radioactive
decay products as a chained series of transformations. Most radioactive elements do not decay
directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is
reached. Decay stages are referred to by their relationship to previous or subsequent stages. A
parent isotope is one that undergoes decay to form a daughter isotope. The daughter isotope may
be stable or it may decay to form a daughter isotope of its own. The daughter of a daughter
isotope is sometimes called a granddaughter isotope. The time it takes for a single parent atom
to decay to an atom of its daughter isotope can vary widely, not only for different parent-
daughter chains, but also for identical pairings of parent and daughter isotopes. While the decay
of a single atom occurs spontaneously, the decay of an initial population of identical atoms over
time, t, follows a decaying exponential distribution, e-?t, where ? is called a decay constant.
Because of this exponential nature, one of the properties of an isotope is its half-life, the time by
which half of an initial number of identical parent radioisotopes have decayed to their daughters.
Half-lives have been determined in laboratories for thousands of radioisotopes (or,
radionuclides). These can range from nearly instantaneous to as much as 1019 years or more.
The intermediate stages often emit more radioactivity than the original radioisotope. When
equilibrium is achieved, a granddaughter isotope is present in proportion to its half-life; but since
its activity is inversely proportional to its half-life, any nuclide in the decay chain finally
contributes as much as the head of the chain. For example, natural uranium is not significantly
radioactive, but pitchblende, a uranium ore, is 13 times more radioactive because of the radium
and other daughter isotopes it contains. Not only are unstable radium isotopes significant
radioactivity emitters, but as the next stage in the decay chain they also generate radon, a heavy,
inert, naturally occurring radioactive gas. Rock containing thorium and/or uranium (such as some
granites) emits radon gas that can accumulate in enclosed places such as basements or
underground mines. Radon exposure is considered the leading cause of lung cancer in non-
smokers.

directly to a stable state.
n should be 5 here Calcium sulfate (or calcium su.pdf
n should be 5 here Calcium sulfate (or calcium sulphate) is a common laboratory
and industrial chemical. In the form of ?-anhydrite (the nearly anhydrous form), it is used as a
desiccant. It is also used as a coagulant in products like tofu.[3] In the natural state, unrefined
calcium sulfate is a translucent, crystalline white rock. When sold as a color-indicating variant
under the name Drierite, it appears blue or pink due to impregnation with Cobalt(II) chloride,
which functions as a moisture indicator. The hemihydrate (CaSO4·~0.5H2O) is better known as
plaster of Paris, while the dihydrate (CaSO4·2H2O) occurs naturally as gypsum. The anhydrous
form occurs naturally as ß-anhydrite. Depending on the method of calcination of calcium sulfate
dihydrate, specific hemihydrates are sometimes distinguished: alpha-hemihydrate and beta-
hemihydrate.[4] They appear to differ only in crystal size. Alpha-hemihydrate crystals are more
prismatic than beta-hemihydrate crystals and, when mixed with water, form a much stronger and
harder superstructure.[5]

Why does one would like all of this social control stuff the most g.pdf
Why does one would like all of this social control stuff? the most goal is to avoid redundancy in
your knowledge. Redundancy will result in numerous anomalies once you modify your
knowledge. each truth ought to be keep just one occasion and you ought to grasp wherever to
seem for every truth. The social control method brings order to your file. you choose to evolve to
bound rules wherever every truth is keep.
Nowadays the go-to traditional types ar either the Boyce-Codd traditional form (BCNF), that
we\'ll cowl here these days, or the third traditional type (3NF), which can be coated later. (Yes,
there are the primary, second, fourth, fifth traditional type. We’ll mention them later.)
The Boyce-Codd traditional type
A relative schema R is taken into account to be in Boyce–Codd traditional type (BCNF) if, for
each one among its dependencies X Y, one among the subsequent conditions holds true:
X Y could be a trivial useful dependency (i.e., Y could be a set of X)
X could be a superkey for schema R
Informally the Boyce-Codd traditional type is expressed as “Each attribute should represent a
truth concerning the key, the total key, and zilch however the key.”
