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 graph sheet

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 fields
in biology. Some of the nine...show more content...
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 am writing to convey my interest in pursuing a M.S. with the Department of Biology. In February 2013 I received a bachelor of science in biology
from the University of Massachusetts, Amherst. In the future I want to conduct research that would answer fundamental questions of ecological and
evolutionary biology with applications toward conservation and natural resource management. The best approach to achieve this goal is to gain a
comprehensive and interdisciplinary perspective. Mississippi State University offers a multidisciplinary biology program with a chance to collaborate
with respected scientific professionals. While I was an undergraduate student at UMass I made it my mission to explore as many experiences and

Since learning of this I have a better understanding of my shortcomings and I have been able to academically improve. I know that when taking the
proper precautions, I am an exceptional student and I have no concerns that I would be able to handle the work involved in a graduate program. One
of the many things I have learned about myself is that I have an incredibly drive, endless curiosity, and I have a passion for science that I wish to pass
on to others. I know that with the help of Mississippi State University I can achieve all my goals and make an impact within the scientific

Biology And Life : A Study Of Life
College is a time of finding out who you really are, what you like, what you hate, and what you want to do for the rest of your life. In High School,
you did not have to know what you wanted to do, and if you did, then kudos to you. Most college students do not know what they want to major in
and that's okay. It means that you're waiting for something to "click" with you. I understand completely, I spent a while myself not knowing what I
wanted to major in until one day I realized how beautiful life is. That's when it clicked for me to major in biology.
Biology is derived from the two Greek words, "bio" which means life, and "logos," which means the study of. Biology is the study of life and living
organisms. When someone mentions biology, what comes to mind? Do memories of learning about how Monarch Butterflies migrate to Mexico to
hibernate come to mind? That's a miracle of nature. The actual definition of biology as transcribed from the Merriam–Webster Dictionary says, "A
branch of knowledge that deals with living organisms and vital processes. Which also includes the plant and animal life of a region or environment
and the life processes especially of an organism or group" (Merriam–Webster). If you were to look out your window what would you see? You might
see leaves beginning to change colors, squirrels storing acorns for their little ones. Look even closer and you might see some honeybees pollinating
some bushes and if you're lucky enough, you might even see a

I volunteered in various health sectors: nurseries, Sunday schools and GP surgery. During my summer holidays, I helped out in my local GP surgery.
Under the guidance of a Nurse practitioner, where I observed communications between a patients and a nurse practitioner, based on minor illness and
often engaged into the conversation. Additionally, I also had a day where I learnt phlebotomy, where blood sample's are taking from the vain using
vacutainer or finger pricked with a sharp and blood specimen is taking for a minute checking for blood glucose or HIV. This enable me to gain few
clinical skills and enables to communicate between patient and family members, which only nourished my hunger and desire to partake in a role that

BioEthics Essay example
As technology advances and medical procedures and research expand, new treatments and new conflicts are created. A problem that has always
plagued medical science is failing organs. As of today, organ failure is impossible to reverse and the only solution is replacement. There is a massive
demand for healthy organs and with this demand comes the issue of bioethics.
The issue of bioethics has become so prevalent it has also arisen in popular culture. The best example of this being the movie Repo! The Genetic
OperaВё which takes place in the future, years after an epidemic of organ failure wreaked havoc on the population of man. During this time a
"savior" arose in the form of Rotti Largo who developed the Bio–Tech Company GeneCo. GeneCo...show more content...
The current system of acquiring an organ donation is through a wait–list called the allocation system, which was supposed to be resolute. However,
there are a few exceptions to the wait list causing this entire system to become even more unfair. For instance, when an organ donor dies his or her
organs are more likely to be given to family members on a wait–list rather than those who are actually next in line (Hanto). Wait–lists are meant to be
fair because those put on the list first are supposed to get organs first, but how fair is that really? How badly one needs an organ for his or her
survival should rank higher than how quickly he or she found about his or her physical defects. Another factor that should be taken into account
when placing people onto a wait list is their age. It makes more sense to give younger people a chance at life than prolonging the life of someone
who has already lived to a ripe old age, but most supporters of the allocation system will argue that all lives are worth the same, even though there are
clear lines between who will benefit more from organ donations.
The most controversial issue with receiving organ donations is that the donor cannot legally choose who the recipient will be in most cases. Of
course in a situation where one's parent is dying, one is allowed to give up an organ if it is a good match, but if one decides to donate a kidney to his or
her best

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

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

Biology Personal Statement Essay
My interest for biology has been developing all through my childhood and teenage years. I have always enjoyed being outside looking for
invertebrates and seeing the variety of species outside. I am intrigued by the way the human body has evolved and carries out so many different
functions, at both the microscopic and macroscopic levels. Studying biological sciences will provide me with the pathway that I have always wanted in
order to understand the world and organisms within it.
While studying A–level Biology, the topics on the 'voice of the genome' and 'genes and health' have been of particular interest to me. I went on a

Psychology has allowed me to deepen my knowledge of neurobiology and behaviour of organisms whilst extending my ability to work with both
qualitative and quantitative data. I believe this skill will be important in a biology course as I will need to be able to manipulate data recorded from
experiments. Chemistry has allowed me to expand and refine my laboratory skills, including what precautions and procedures are necessary
throughout all scientific experiments. This practical component of Chemistry will help when studying Biological sciences as I will need these skills
in the lab, for example when handling chemicals and equipment. All of my subjects have enabled me to develop my researching, analytical and
problem solving skills, which is a vital part of a biological degree.
To further my knowledge into biology, I have been partaking in an online course about epidemiology which focuses on the influenza virus. It
involved the evolution of the virus from the first pandemic in 1918 to the common cold at present. This course has given me a perspective of what
the microbiology and immunology topics at university will involve. I have also done some extra reading, for example, I have read articles from
Microbiology Today, The Big Picture and Biological Review. Additionally, I have read 'The SelfishGene' by Richard

Ap Biology Reflection
This course was easily relatable to my AP bio course I took my senior year of high school, and my biology lab that I took this fall semester my
freshman year. The lab and the lecture went hand in hand which helped me academically learn more. I noticed that by taking these two courses
together it helps me learn more and better understand the material that I need to study/ know. All my knowledge of this course I mainly learned my
senior year of high school through AP biology, although this course really emphasized my essential understanding of the course and went into more
depth of the criteria that I needed to better know. I have acquired new ways of seeing, being, and thinking of this course because of the way it's gone
about. By being in this

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

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

Bio Engineered Foods Essay
The advancements in the field of biotechnology have enabled scientists to aid the production of bio–engineered food products. Bio–engineered foods
are created with the insertion of a new gene into a plant or organism to change it's traits. This altercation of DNA produces new proteins that create
this change. In order to better fill consumer demands and receive a larger profit, farmers use genetically modified crops to: help assure a longer plant
life, improve nutrition in food, and resist certain herbicides. With these changes comes fault, after the plantation when this food hits the market there is
no mandate for the labeling of genetically modified foods. It is believed that these foods have their benefits, however, their risks hold a...show more

As the dangers begin to pile the possibilities become dire, "Many children in the US and Europe have developed life–threatening allergies to peanuts
and other foods. There is a possibility that introducing a gene into a plant may create a new allergen or cause an allergic reaction in susceptible
individuals ... Extensive testing of GM foods may be required to avoid the possibility of harm to consumers with food allergies" (4). It is
obviously necessary that genetically modified foods be closer studied before they can be declared safe. Other risks pertain to consumer health,
"Many people believe that organically produced foods are, in some way, healthier than conventionally produced foods, and they seek out products
that are labeled organic because organic agriculture shuns synthetic chemical pesticides, herbicides, and fertilizers" (2). It shouldn't be an issue if
consumers want options, especially to stay healthy. Putting consumers at risk for the sake of not writing text on a label, isn't worth it. If genetically
modified foods are so safe then why has it become an issue to label them? Without the mandatory labeling of these foods, this is a risk the consumer
has no choice but to take. An even bigger drawback of bio engineered food is their effect on the environment. Not only can these foods effect humans,
they effect nature and wildlife as well, "B.t. toxins kill many species of insect larvae indiscriminately; it is not possible to design a B.t.

The Biological Perspective : Psychology Essay
PSYCHOLOGY 1010: CONTEMERORY PSYCHOLOGY:
1.The Biological Perspective: This is the study of exactly how the physical events within the physical body interact with the events in the external
environment. This is expressed by our perceptions, memories, behaviors and interactions with everything around us. We can think about our heredity
and genetic makeup and the influences that has on each one of us as an individual. Then think about the stress of poor health and illness and how we
may express our emotions with those around us. Since we are diverse as individuals we rely on our physiological make up and the stimuli of our
environment to adapt to each situation. This human biology helps us to constantly adapt and survive in an ever–changing world.
2.The Behavioral Perspective: This perspective is based on environmental rewards and punishers to encourage or discourage behaviors. This is usually
notes through direct observation of the particular act in the specific environment. Social cognitive learning is used to further explain values,
expectations, and intentions of the individual. This theory was the main stream behaviorist theory for over 50 years, as it focuses on precision and
objectivity. It is thought to have advanced science as a whole and has given psychology some of the most accurate and detailed finding to date.
3.The Cognitive Perspective: This is a way to explain how an individual's thoughts and explanations have a profound effect on their actions feelings

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 more content...
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

to work in the field of genetics and do research that will save many

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

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

Anna Freud. Bio Essay
Anna Freud The philosophic contributions to the formal discipline of psychology have primarily been dominated by male visionaries, but many
notable women pioneered a role in the history of psychology between 1850 and 1950. Sigmund Freud was not the only Freudian to establish credibility
in the field of psychology, as his youngest daughter Anna Freud pursued a career in psychology and made significant historic contributions. Anna's
background, theoretical perspective, and contributions to the field of psychology will be discussed.
On December 3, 1895, Anna Freud was born to Sigmund and Martha Freud in Vienna, Austria. Anna was the youngest of the Freud's six children. She

Followers of Anna and Sigmund Freud's teachings are usually represented by ego psychology. Modern day ego psychology remains loyal to Freud's
work with a psychoanalytic foundation but is more practical and ordinary of the ego in psychoanalytic application (Boeree, 1998). Erik Erikson, who
is well–known for his expansion work in the field of ego psychoanalysis, was mentored by Anna who impacted Erikson's academic and professional
career in psychology. Anna and Erik met when he tutored children at the Heitzing School run by Dorothy Burlingham, Anna's longtime friend. Anna
observed Erikson's skillful manner with children and expressed interest in guiding him to learn more about child psychology (Erik Erikson, 2010).
Anna's main passion was child psychology, where she dedicated her time and energy to studying and analyzing children suffering from the impact of
war. Many of these children were predisposed to enduring traumas, many were handicapped or blind. Her father had concentrated entirely on adults,
which sorted through childhood recollections instead of present events. Anna desired to work with children suffering from present traumas to prevent
psychological complications in adulthood. She observed children and their own environment and became an authoritative therapist to deal with the
transference problem. She was reported as being a caring adult that was not a substitute parent or new playmate

Current advances in biotechnology through massively parallel sequencing, or Next Generation Sequencing (NGS), has allowed for the investigation
and in–depth sequencing of the human genome particularly for the study of biological markers, translational research and genotyping. Upon discovery
of cell–free DNA in maternal plasma, implementation of Non–invasive Prenatal Testing, or NIFTY/NIPT, has been actively performed throughout the
globe to test for fetal chromosomal abnormalities, particularly Down's syndrome. Detection rates of fetal aneuploidies can be done in the first and/or

Each clinic has set several standards and cut–off ranges in order to reduce the rate of false positive that is dependent on the age of the pregnant mother
and the ranges set by the clinic itself (De Jong, A., Dondorp, W. J., et.al., 2010). The age of a pregnant woman can cause high–risk scenarios and
increases the chance of fetal abnormalities. A study conducted by Dr. C. Lewis and associates (2014) have shown that most pregnant women seeking
NIPT were typically older, predominately white, and well–educated. Furthermore, with the utilization of NIPT worldwide, there are various factors
contributing towards higher aneuploidy rates, especially in lower middle class communities, urban areas, and the slums.
Dr. C. Lewis and associates (2014) produced statistics that have found that there are typically higher rates of aneuploidy in rural and urban areas
because women tend to marry or conceive children at age 35 and older. Likewise, due to high consanguineous marriage rates in many parts of the
Middle East, there is a higher incident and increased rate of delivering a child with birth defects or a genetic disorder (Allyse, M., Minear, M., et. al,
2015). These studies have supported that although the number of cases associated with children born with a genetic disorder is unknown, there is a
high correlation associated with increased age of conception of the mother with some growing evidence of high paternal age as well, thus leading to
high termination

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
