The temperature is so high that the active site of the enzyme changes and it is unable to bond with
substrates.
Part I:
Effect of Temperature on Enzyme Activity(Invertase)
The rate of an enzyme–catalyzed reaction will increase with temperature to maximum rate and then
sharply decrease. The rate increases to about 40 degrees Celsius, at which point the structure of
proteins is disrupted (denaturation), resulting in an abrupt loss of enzyme activity.
PROCEDURE:
1. Number 3 test tubes (1,2, and 3) with a permanent marker. Add 4 ml of a sucrose solution to each
test tube.
2. Place tube 1 in a beaker of ice water; place tube 2 in a beaker of water at room temperature, and
tube 3 in a beaker of boiling water. Wait 10 minutes for the sucrose solution in the tubes to
equilibrate with the temperature of the water in the beakers.
3. After 10 minutes, add 0.5ml of 25 percent invertase (an enzyme derived from yeast) solution to
each tube (swirl the invertase solution before use). Cover each tube and invert it several times to mix
the contents during the 5 minutes.
4. After 5 minutes add 1ml of Benedict's solution to each test tube. Place the 3 tubes at the same
time in a boiling water for 5 minutes.
5. Remove all 3 tubes from the water bath at the same time and observe the amount of precipitate
and the color of the Benedict's solution in the tube. Then I would record my observation on a data

Wildlife Conservation and Biology Essay
There are 6.5 million species of land mammals. Wildlife biologists get the privilege of studying
and spending time with these animals as their everyday life. I should be a wildlife biologist so I
can study land mammals. Wildlife biology is a field of biology in which land animals are studied. It
deals with all animals with backbones and studies individual species of wildlife, their habitats, and
surrounding ecosystems (Fitzgerald). It also studies how animals may interact with their ecosystem.
Without wildlife biology we would not have extensive knowledge of other animal species, and how
they could be linked to humans. Wildlife conservation in the United States has been based on the
Public Trust Doctrine where in wildlife and...show more content...
The first national park, Yellow Stone National Park, was established in 1872 by Ulysses S. Grant
(Brown). This was one of the last explored areas in the west. This establishing of a national park
led to more wildlife conservation national movements. In 1887 President Roosevelt gathered a
group of influential American hunters in New York to form the Boome and Crockett Club with a
mission of preserving big game in North America (Brown). In the 1930's management of wildlife
resources began in earnest. Funds were mostly provided by levies on hunters (Brown). The 1930s
were also the beginning of wildlife research in the United States. The leader of this effort was Aldo
Leopold (Brown). Wildlife biologists need many years of schooling and hands on experience to
become experts at their jobs. Altogether with bachelors, masters, and doctorate degrees, it is close to
12–14 years. Each university is different in how many credit hours are needed. The areas are
general biology, ecology, genetics, cellular biology,evolution, wildlife management, and fisheries
management (Everyday Life). Deciding on a school is based on what area I want to work in. If I
want to be a marine biologist, schools on the coasts of oceans are the best for me to go to. To
become a wildlife biologist, colleges with programs that focus on land mammals are the best
option. One college that is very popular for this study is Texas A and M University. Texas A and M
University is constantly ranked among

Structure And Function Of Biology Essay
Introduction
Structure and function in Biology is a broad concept that can be explored within a diverse range of
topics across the subject matter. The following essay will be focussed mainly on the subject of
Deoxyribonucleic Acid, or more commonly DNA. DNA is a highly complex, intricate and
extraordinary macromolecule found within all living cells. DNA is a "biochemical noun" and can be
defined as "...a self–replicating material which is present in nearly all living organisms as the main
constituent of chromosomes. It is the carrier of genetic information." [Oxford Dictionary, c2016]
DNA is found in the nucleus of eukaryotic cells, enclosed within a double membrane. Eukaryotic
cells are multifaceted and require a high level of regulation to ensure smooth functioning. The double
membrane of the nucleus allows gene expression, a key function of DNA, to be efficiently regulated.
Furthermore, DNA is found in large quantities within the eukaryotic cell. Human cells alone have
around 1000 times more DNA than typical bacteria [Alberts, c1989, p.23]. DNA, both on its own and
with other molecules, plays a huge role in the making of an organism, from the importance of its
chiral helical structure and its main functions, to the vast vicinity of error and inaccuracy that a
small change to the genomic sequence can cause. It is the foundation upon which an organism is
built and the main contributor to an organisms genotype and phenotype. But what are the
constituents of DNA and can it

Synthetic Biology? Essay
Impacts on the Environmental Movement David Park, Expos 101, Prassack, 11/15/2011 The
environmental movement, addressed in "Rewilding North America" by Caroline Fraser, focuses on
the negative outcomes of human activities in the environment. It is a movement that restores the
environment that humans have damaged. Scientists have addressed the idea, in "A life of its own"
by Michael Specter, of using synthetic biology to mend environmental issues. Synthetic biology
combines the "elements of engineering, chemistry, computer science, and molecular biology...to
assemble the biological tools necessary to redesign the living world" (Specter 364). There are both
positive and negative impacts of a synthetic world on the environment movement....show more
content...
However, synthetic biology would essentially compete against rewilding for funds, and hinder the
environmental movement. One example of the competition between the environmental movement is
the option of using cores and corridors versus to previous established programs. Initially, the
promotion of cores and corridors was rejected by the organizations at first. Later on, rewilding
advocates created a new group, "seeking to reshape the environmental movement," and acquired
money from Tompkins and Johns. The rewilding movement ultimately took money away from other
programs, and changed the concept of the environmental movement. Now another decision has to be
made between rewilding and synthetic biology. Because money is limited, organizations can only
support a limited amount of movements. By funding synthetic biology, other environmental
movements will be halted, whether it is better or for worse. The environmental movement is
important, but it does not take priority over synthetic biology. On the issue of nature, the
environmental movement and a synthetic world stand at different spectrums. Nature has constantly
been molding the earth, and ever since humans came, with their technology, the environment has
started to deteriorate. The movement for nature focuses on the negative impact of humans on to
nature. Many of the movements that are in affect "recognized that wilderness cannot be preserved

Analysis
Analyze the data you collected in the lab. How does the data presented above relate to the
hypotheses you generated earlier in lab? Are any hypotheses disproved by your experiment? Use
your graph to determine the boiling point of a solution made with 2 ВЅ tablespoons. This use of a
graph has generated a hypothesis that a 2 ВЅ tablespoon solution boils at __219__degrees F. Prepare
a 2.5 M solution and verify your hypothesis.Correct!
Is the hypothesis correct? Yes. Adding table salt to water causes the water to boil at a higher

temperature.
Problems with doing the experiments. The temperature readings were hard to make. Gloves had to
be worn to keep my hands from getting too hot. Had to be careful that the stove heat was not hitting
the thermometer.
Other things learned. Be careful when adding salt to boiling water. It makes the water boil
vigorously for a second or two.
Conclusion After conducting the experiment, how would you now explain the problem(s) or
answer the question(s) raised when you described the purpose of the lab? Be sure to base your
answer on the data you collected. If you are given a

Biology Reflection
As the bell rung for the end of first period, I gathered my things and began to walk to my second
period class, Biology. Biology was always to me the hardest subject I had ever dealt with because
there was so much to learn, study, and truly understand. I walked through the door into the
classroom and I'll never forget the words I heard my teacher say that caught me so off–guard. "Get
out your notes and study because you have a test today", he said. As I heard him finish his
sentence, my eyes widen and I quickly moved towards my seat and began to skim over my notes as
fast as I could. I had completely forgot that I had a test in biology.
While reading over my notes, I kept thinking to myself that I just knew I was going to fail this
test. After a couple of minutes of studying, I heard the teach yell "5 more minutes". I began to
skim even faster over my notes. It felt like time was moving so fast because when I heard my
teach yell "times up", it seemed as if only 2 minutes had passed by. He passed out the answer sheet
around the classroom and instructed us to fill out our student ID numbers. I looked over the unfilled
answer sheet and counted the amount of questions. There were 30 questions in total which
frightened me even more because I had to answer 30 questions on information that I barely studied.
Then he handed out the test and I became extremely nervous because not only did I barely study and
there were 30 multiple choice questions, but the classroom was so cold that

Biology Major Essay
My listed major at George Mason University is Government and International Relations. Prior to
being an humanities major, I was a biology major. After switching over to my current major, I
continued taking courses in the natural sciences, courses specifically fulfilling the prerequisite
courses for admission into Dental School. I do truly enjoy my current major, but I believe it would
be more fitting for this paper to be written from a biology standpoint. This excerpt will touch on the
study of biology, and science subfields and their use in career paths such as Dentistry.
In accordance with Oxfords English Dictionary definition, biology is defined as "The study of
living organisms, divided into many specialized fields that cover their morphology, physiology,
anatomy, behavior, origin, and distribution." (Oxford, 1) More specifically to the major itself,
according to George Mason's Biology Department Program Goals and Student Learning Outcomes,
the curriculum aims to satisfy the following four program goals: "Knowledge of biology,

Similar to other academic fields, each specialty and subfield requires students to fulfill the basic
prerequisite courses, such as chemistry, organic chemistry, and physics. Even if a student is not a
chemistry or physics major, these courses are germane for true progression within the field. As a
basis of comparison and experience, a government and international politics major could not succeed
within their field nor career goals without a basic government 101 courses or an introduction to
international relations course. Each subfield within biology focuses on mastering the four program
goals in respect to their concentration, but not before mastery of the prerequisite courses that enable
them to do

Why I Chose Biology
Until I started high school, I had no idea what major I wanted to pursue in college. After all, there
are so many options, and even though some people know what they want to do from the time they
are in elementary school, that was not my experience. Although I always had some ideas before
entering ninth grade, I was still waiting to find something I really loved. During my freshman year, I
finally found that thing–– biology.
Before high school, I had never looked forward to a science class. The only reason I even took
biology freshman year was because it seemed to be the lesser of two evils, the other being earth
science. As it turned out, that biology class became the most pivotal course I took during my four
years of high school, and was a major factor in my decision to choose biology as my major....show

Because genetic research is so new and so many possibilities for using this new technology are
still being uncovered, I could have the ability to do major research in the area through my studies
at Johns Hopkins. For example, although scientists know some of the uses of stemcells, they also
know that there are many more things they can be used for that have not been found yet. I am
hoping that by majoring in biology, I will have an opportunity to work in the field of genetics and
do research that will save many

Evolutionary Biology Essay
Evolutionary Biology:
Global Warming Negatively Affecting Ecosystem's and Organisms Within
Daret Mckay
Sydenham High School
By looking at the evolution of the Earth's climate, we can see that climate change is occurring but
more specifically, global warming. Climate change is occurring as a result of the green house affect,
meaning that sunlight's energy and heat is being trapped within the Earth's atmosphere and
furthermore warms the surface of Earth (NASA, n.d.). Evolutionary biology is described to be
genetic inheritance (or change) within a population from generation to generation (Understanding
Evolution, 2015). By examining the evolutionary biology of ecosystems and the organisms within it,
we will see that global...show more content...
Climate change is altering the pattern of life on the planet, causing widespread species
extinction, migration and behavior changes (Suzuki, n.d.). For example, female caribou migrate
in the spring to small pockets of vegetation where they feed and raise there calves, but for the last
decade spring has come so early that by the time the caribou reach the coastal plan, their principle
of food plant has already gone to seed (Suzuki, n.d.). This proves that the female caribou are going
to have to change breeding time frames, as well as migration, which will have an overall affect
on the ecosystem. This also means that animals and plants will have to permanently migrate to
find suitable habitats but some will not be able to move fast enough to keep up with the pace of
climate change (Suzuki, n.d.). In fact, by saying that it means that some species will have to
move 10 times faster than they did during the last ice age just to survive. Over 30% of land
surfaces in Canada will require unrealistically high migration rates to keep up with projected
climate change (Suzuki, n.d.). Another example of this issue is with Collared Lemmings. They are
an important prey for snowy owls, which may lose as much as 60% of their habitat. Loss of tundra
habitat could radically reduce the availability of vital breeding habitat for millions of geese and
shore birds (Suzuki, n.d.). In general ecosystems are being destroyed due to

Why I Chose To Study Biology
Throughout my college education I have taken and will continue to take courses that relate to my
Associate Degree in Science and my future career of being a biologist. I have chosen to become a
biologist because I love to study life. To examine an organism in its natural habitat, amongst other
habitats, is a way for me to examine a beautiful creation. Biology is also how and organism interacts
with other organisms, how an organism behaves, and where the organism came from, amongst other
concepts. One organism, in particular, never ceases to grow and increase. This organism is
classified as Homo sapiens, in other words, a human. Humans are extremely complex and psychology
provides further understanding of the human mind and how the mind affects the human body. The
study of the human mind can also be applied to the study of the mind in different organisms which

The brain is a complex machine and to process perceived information it has to be structured in a
certain way. The brain is a part of the central nervous system, which includes the spinal cord, which
have complex nerve cells (pg 41 Grison, et al. 2017). Nerve cells are named neurons and are used
as a path of fast communication from the brain to the rest of the body. The peripheral nervous
system is the neurons that are in the rest of the body (pg 41 Grison, et al. 2017). Learning what
makes up each nervous system and how they work is a topic that is deeply covered in biology. As
a biologist, the ability to label parts of the nervous system and how they interact, is needed to
examine complex and simple organisms. A sea anemone does not have a spinal cord, meaning that
they also lack brains. However they do have neurons found in their body. How can a creature have
no brain, but have a nervous system? This question is answered and explained through the work of

Biology Is The Science Of Life
Biology
Tania Espinoza–Flores
Abstract
Biology is the study of life. Biology talks about organisms and how they react to certain toxins,
when you mix things up. There are nine fields in biology. Some examples of the fields are
evolutionary biology, cellular biology, and molecularbiology. Biology has a long history. Biology is
beneficial in many ways. Biology has impacted people in negative and positive ways. People who
study biology are called biologists.
Biology, the Science of Life Biology has a long history. Early humans would study biology. They
had to study the animals that they hunted, and they had to know where to find the plants that they
gathered for food. Biology is the study of life. Biology comes from Greek words. There are nine

It is the organisms that work to create new things. An organism is an individual animal, plant, or
single–celled life form. All organisms come together and create something new. The organisms take
energy from the environment, and from the food they eat. The new organisms that the old ones
created will soon make new organisms. This forms a cycle. The cycle never ends until something
bad happens to the organisms. An easy way of saying all of this is by saying that the cycle continues
until something bad happens to the organisms. Biologists are the important scientists of biology.
Biologists study the structure, function, growth, origin, evolution, and distribution of living
organisms. Biologists study living organisms. For example, they study humans, plants, animals, and
many other living organisms. When they study these organisms, they find out many things about life
and they study the medicine that we use, so they can know what types of ways we will react to the
medicine. People from long ago, would use biology to study the animals that they hunted, and the
plants they ate. Indeed, biologists are very important to

I have obtained various skill sets while I was there. During the internship, I was trusted with small
project in the neuroscience field where I have to design and optimise an experiment involving the

has started to grow bigger and stronger. The more I read into molecular medicine, the more I realise
how important genetics regulation is in order to discover and develop technologies to regulate
biological processes and treat various diseases. And maybe, there's hope for Alzheimers's too.
Although it is too late for me to help my late grandmother who passed away last year, my
curiosity still goes on. Throughout the year, biologists hailed plenty of breakthroughs in
Alzheimer's research and neurological diseases. I want to be a part of that. However, I still have a
long journey to go, and this is just the beginning. I could be considered for this scholarship, so that
I dive deeper into the ocean of knowledge and learn as much as I could so that I can contribute to

Relationships and Interactions in Biology Essay
Biology essay – Relationships and interactions
There are many different types of relationships and interactions between organisms. Every organism
is in some way connected or associated with another. Some organisms need to depend on other
organisms to survive which shows how important some of these relationships or interactions can be
in biology. Interaction is a vital part of how many organisms develop over time.
Predation is a main example of a relationship between organisms. Predation involves predators and
prey, such as a fox catching and eating a rabbit. There are two other forms of predation called,
parasitism and grazing. Parasitism is where the host organism is exploited and used for benefit by
the other organism called a...show more content...
Lichens are another example of mutualism. Lichens are formed by algae and fungi living together
and they both help each other. Algae can photosynthesise and make food, which is shared by the
fungus. The fungus in turn shelters the algae from a harsh climate.
Commensalism is when one species can benefit from a relationship and not hurt the other. There are
four different main types; chemical, inquilinism, metabiosis and phoresy. Chemical commensalism
is most often observed between bacteria. It involves the species of one bacteria feeding on the
chemicals produced or the waste products of the other bacteria. Inquilinism involves one species
using the body of another organism as a platform or living space while the host does not benefit or is
harmed. Metabiosis occurs when one species unintentionally creates a home for another species
through one of its normal life activities. A phoresy takes place when one organism attaches to
another organism specifically for the purpose of gaining transportation. An example of
commensalism (inquilinism) is barnacles and whales. Barnacles are non–moving and they rely on
currents to bring them food. Some barnacles attach themselves to whales in order to help them live.
They can benefit as they are then transported over the ocean which exposes them to more feeding
oppurtunities. The whale neither benefits or is harmed by the barnacles.
Competition is a huge

Biology and Chemistry Education is now the order of the day. Many people aim at continuing their
education after high school. After high school, some students enter directly to college whiles others
go to universities to read different course of their choice. Among these courses, some prefer to read
mathematics, literature, science, economics, and others. Every student has his / her own career path
in life. Some aim at becoming Biologist whiles others aim to be a Chemist. This is basically for
students who have interest in the science field determines which areas they want to study. When it
comes to the issue of Chemistry and Biology which one to be chosen from, here lies the individual
own preferences. Biology and Chemistry have similarities in science, whereas they have their
differences and their branches. Chemistry and Biology are related courses so those who are
interested in science–related programs as their career can go for it. The systematic study of all the
matter that exists is science involves both observations and experiments. There are different matters
also exist in the universe. The study of a living organism is Biology. Biology is divided into various
branches such as Zoology, Botany, Taxonomy etc, whereas, Chemistry can be defined as the branch
of science that deals with matter, its composition , reactions, structures, and properties. Both Biology
and Chemistry plays an

Biology : A Career In The Career Of Biology
The career I have chosen to research and write about is biology. The study of life ranges across
multiple options of different sciences. One who wishes to follow in a career involving science
should consider being a type of biologist. This career will improve social skills and experience in the
outside world. Biology is a great career to some into contact with people, animals, and new
discoveries. This essay will highlight key aspects of the career I have chosen.
The duties of a biologist require multiple sets of different skills. Most biologists have to process
any analyzed data and present the research. Another set of required skills are managing lab
technicians and programing computers (Chron.com). Specific types of biologists will need to learn
certain skills to even participate in that field of study. Different types of biologists include wildlife,
aquatic, and plant biologists. Each field has different circumstances of life to study or take care of.
The second branch of biology is botany and that specializes in biophysics and genetics (Career
Discovery Encyclopedia, Page 106).
The word biology comes from the prefix bios, meaning life, and logos (word or discourse). The
study and practice of biology was first recognized by Greek philosophers. The first significant
contribution to biology was by a man named Alcmaeon. His work would have been published at
some point between 500 and 450 BCE. Alcmaeon was the first to identify the difference between
understanding and

Biology And Modern Biology
Biology Professions
Science requires the testing of ideas using evidence. It uses critical thinking, careful data collection,
peer review, and communication of results. Biology is a natural science that concerns the study of
life and living organisms. Modern biology now studies the structure, function, growth, distribution,
and evolution of living organisms. The general concepts of biology are that the cell is the basic unit
of life, genes are the basic unit of heredity, evolution is the reason for unity and diversity, organisms
survive by consuming and transforming energy, and all organisms maintain a stable internal
environment (Lumen 2013). Biologists can range from being in research, to education, to healthcare,
to environment management and conservation. Some biology jobs only require a two–year
associates degree or certificate. Others need a bachelor's degree or even more school such as a
master's or doctorate. (American Institute of Biological Sciences, 2005).
Clinical Laboratory Technologists collect samples and perform tests to analyze body fluids, tissue,
and other substances. Clinical Laboratory Technologists manage the laboratory for hospitals,
doctors, diagnostic–services companies, blood banks, and clinics (College Board 2005). An
entry–level job for technologists usually requires a bachelor's degree in medical technology or life
sciences. Some states require laboratory technologists to be licensed, but not all. Employers typically
prefer to hire certified

Lactase Experiment
The results of the experiment vary from what is reported by previous studies (Curry, 2013, Enattah
et al., 2002, & Tishkoff, 2007). The experiment was conducted on students currently in the Biology
225 course in Schenectady, NY. The class was primarily composed of individuals whom are
descendants of Europe. Therefore, an assumption was made that by in large, the percentage of lactase
persistent in the class that was expected was going to be near 95% (Curry, 2013). However, such a
high percentage was not found. Of the class, only 49.3% of individuals were determined to possess a
genotype that results in a phenotype of lactase persistence. Conversely, 40.8% of the class was found
to carry the genotype lct/lct which results in the phenotype of lactase non–persistence. Therefore, the
results are nearly 50% off from what we expected initially. This could be for numerous reasons,
but perhaps the assumption should not have been made. The results fit much better when
compared to the world average occurrence of lactase persistence. Curry notes that out of all
individuals over the age of 8 years old, only 35% still possess the ability to digest and breakdown
the lactose in dairy products (2013). The results do fit closer to the world average, therefore
indicating that the assumption may have been wrong, the results of the experiment still do not
necessarily indicate whether the total population of students in the Spring 2016 Biology 225 class
fits the societal model where there is a
