Biology Experiment Hypothesis I predict that the potatoes in the solution with high sugar concentration will increase in mass the most, the potatoes in the water with no sugar will lose the most mass. Osmosis is the movement of water from a high concentration to a low concentration across a particularly permeable membrane. The water can move between the potato and the solution but the sugar can’t because the molecules are too big to pass through the membrane. The water will move
Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. Besides that we have been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol level, excitement, mass, age, temperature and exercise affected the heart. Diet and exercise were the only 2 doable and so my partner and I chose exercise. We determined
Counterfeiting: We're In The Money A frequently asked question by a customer is "Can you break a hundred dollar bill?" If this request has been granted, why do the cashiers take the bill and turn it into a biology experiment? Between pouring a liquid on the note and/or holding it up to the light to check for authenticity, is our currency system in danger? As of the beginning of 1996, the Chairman of the Federal Reserve and the Secretary of the United States Treasury, prove their economic wizardry
Osmosis In A Potato Intro: ====== My biology coursework is based round the osmosis process that takes place in potatoes. Osmosis is the intake of a salt solution through a selectively permeable membrane. The strength of a salt solution can have a dramatic difference on the amount the potato can take in, and how it reacts. Here is an example of a selectively permeable membrane… Salt Solution [IMAGE][IMAGE] Strong Weak [IMAGE] Strong Weak Salt Solution
Introduction The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature
Biology can be viewed as being similar to the idea of nature while the environment is similar to the idea of nurture. A long time ago we agreed that biology choices might shorten our lives but would not change our genes. Also any effects on the environment on the genes would not happen too quickly. Epigenetics play an important
Laboratory experiments on animal Jack stumbled upon an article, about how animals are being abused, tortured and killed for the things we commonly use in our household. Written on the article is how a female dog, named Libby have gone through in the hands of researches, it says there that pharmaceutical companies have paid the laboratory to infect animals with worms, fleas, and ticks and smear toxin in their skin to test animal companion products, Imagine how animals are being treated in the confines
There are many stages of psychology which have developed over time. Greek philosopher Socrates (469-399BC) was interested in studying the reincarnation of the soul and mind, which he believed contained the knowledge. The soul and mind were considered as the representation of individuals. He believed that we needed questions and answers to reveal the truth; this method is known as Dialectics (BC, 2012). Plato (384-347BC) was a bright student of Socrates who devoted his life to philosophy. Plato lengthened
taken into shelters or pounds and if not claimed or adopted they are euthanized or become test subjects. According to PETA, People for the Ethical Treatment of Animals, “each year, more than 100 million animals are killed in U.S. laboratories for biology lessons, medical training, curiosity-driven experimentation, and chemical,
My academic degrees are in Biology (Bachelor of Science) and Molecular and Cellular Biology (PhD) with specialties in genetics, disease, and molecular biology. I have worked in a variety of different labs, and conduct basic scientific research with biomedical implications. Throughout my experience, I have developed a wide range of skills, mostly focusing on molecular biology techniques, bioinformatics, and tissue culture. I am very passionate about applying these skills towards studies of cancer
in experiments each year across the world. Scientists say that animal experimentation is necessary for a variety of things. Others say there is no other way scientists can achieve their scientific objectives (RSPCA). It is cruel to experiment on animals even if scientists state that they can not find another way to accomplish their scientific objectives. The animals are practically living a miserable and terrifying life. Some scientists state that animals do not suffer during the experiment, it
intense interest in Biology. I am interested in the knowledge and understanding of biological processes occurring at cellular level, and thinking about answers to the unknown, for example the biological importance of sleep. I am also fascinated by genetics because it amazes me, how a single gene mutation will cause the entire amino acid sequence to change, which will cause a widespread impact on the organism, and change how they interact with the environment. My interest in Biology has motivated me
A Look at the Other Side of a Heated Debate Animal experimentation has always been a highly debated topic. Many have argued for the use of animal experimentation claiming that animal experimentation is the only possible way to find medical treatments to preserve human life. However, animal rights activists have argued that animal experimentation is futile and that it is unethical to use the life of an animal for experimentation without the animal’s consent. Although both sides of the debated issue
According to an article by PETA, “experiments on animals are cruel, expensive and generally inapplicable to humans” (PETA 1). This shows how not only many laboratories and companies that use animals in their experiments are wasting money and time, but also wasting countless lives of animals. As a human, one does not have to suffer through unconsenting pain because no one would
Egg Albumen Experiment The purpose of this investigation is to establish which is the lowest concentration of Copper (II) Sulphate solution that will denature a sample of egg albumen (egg white) at room temperature. The base of the reaction is the globular protein (albumen) being denatured by a heavy metal (Copper (II)), the copper (II) reacts with the NH3 group causing it to denature, this means the proteins' secondary and tertiary structures are being altered and refolding into different
is written by Don Robertson. Don Robertson is a gay teacher of biochemistry and molecular biology. In his article, he states that many experiments have proved the genetic connection to homosexuality. He names some of the experiment's methods but he doesn't include who ran the experiments, where they were done, why or why not they would be reliable or whether they would have the same results if the experiments were repeated. He comes up with figures like if one identical twin is gay there is a sixty-
Biology and chemistry are my most favorite subjects since high school. Initially, it was because they offered me opportunity to work with exciting reactions and instruments. Once I gained more knowledge in the fields, however, I started to appreciate their values. This led me to start doing research in high school, and continuing into college, when I realized that I had found my true passion of working in laboratory. Besides research, the knowledge from taking several classes in biology and chemistry
as foods or drugs. According to The People for the Ethical Treatment of Animals (PETA), scientific experiments have required animals to “inhale toxic fumes,... remain immobilized in restraint devices for hours,... suffer through the drilling of holes into their skulls,... withstand the burning of their skin,... and endure the agony caused from the crushing of their spinal cord”(“Animal experiments: overview,” n.d.). Testing harmful products on animals everyday creates a long lasting effect on the
places like Africa and the Amazon to study the different animals in those two places. I would like this job because I could be In a office writing, conducting census projects, research studies, and conducting more experiments. But I could also go in to field work. Travel around the world to study these animals and there eco systems. The way some animals eat, the way they communicate, the way they feed. I could learn all these things
to help people. Why I like this job is because I would get to experiment every day and maybe discover cures for things that we don’t have cures for. I would also like to help as much as I could with Pharmacist’s and give them as much as I could to help people. The role that Chemical Technicians do is having the backbone to every chemical, semiconductor, and pharmaceutical manufacturing operation. Chemical Technicians explain experiments, record data, and help use new processes and procedures in the
