Investigate the effect of on exercise on the heart rate. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Equipment needed: Stop watch Screen volunteer P.E kit Calculator Record sheet Type of exercise: skip for few minutes ‚ then break in between and again repeat it once or twice. Method: First of all‚ we needed to take the resting heart rate of the person who is about to skip. Then‚ with the stopwatch one

The Stanford Prison Experiment was a very unique and brutal experiment. In 1973 the professor Philip G. Zimbardo set out to study how normal subjects such as college aged men would react as “prisoners” and “guards” in a mock prison setting. Stanford set up what they called a “mock prison” in the basement of Stanford University’s psychology building. During the experiment there were ten prisoners and eleven guards. The prisoners were stripped of their uniqueness by being dressed in matching smocks

Animal testing has been around since Aristotle’s time. Since then animal testing really took off for medical uses in the early 19th century. Since then laws have been put on animal testing when congress passed the Food‚ Drug‚ and Cosmetic Act in 1938. It is estimated that 26 million animals are abused in animal testing annually. Some of the causes include animal testing cannot stop or we would have no way of knowing if something is safe or not‚ assuming that animals and humans have the same DNA‚

is essential for human survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution.

"More than 100 million animals are poisoned‚ burned‚ crippled‚ and abused in other ways in U.S. labs each year."(#1video) Animal testing became a common method between 200-300 BC‚ these tests were often led by important male figures such as Aristotle. In 1242 Ibn al- Nafis used animals to test blood circulation‚ his theory of human blood circulation was later proven by William Henry many years later. In the 1660’s another scientist‚ Robert Boyle‚ theorized that living beings needed air to live‚

First pass metabolism. Pharmacology is the study of the effects drugs have and how they exert them. Drugs can be administered enteral or parenteral. [1] Enteral refers to any form of administration that involves the alimentary tract. The four enteral routes of administration include the mouth‚ sublingual‚ buccal and rectal. Parenteral refers to routes of administration outside of or beside of the alimentary tract. The parenteral route includes intravascular (IV)‚ Intramuscular (IM) and subcutaneous

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly ’amino acid synthesis ’ is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism ’s diet

Purine metabolism is central to the production of nucleotides in the body. Imbalances in this process can lead to hyperuricemia which is abnormally high levels of uric acid in the blood [>360μmol/L in females and >400μmol/L in males]. Hyperuricemia can lead to uric acid crystals precipitating in the joints‚ skin‚ vessels and other tissues‚ this is a form of inflammatory arthritis known as gout. Uric acid is a metabolite of purine metabolism therefore gout can aptly be characterized as a disorder

The Effects of Aerobic Exercise on Heart Rate Introduction: Our bodies need to be in balance in order to function properly‚ and there are many ways the body maintains balance‚ or homeostasis. Homeostasis is the maintenance of nearly constant conditions in the internal environment. Our normal heart rate is an example of our body in homeostasis and any sort of change‚ or stimulus‚ can alter it. Exercise‚ adrenaline in the blood‚ and a low blood pH are all stimuli that increase the heart rate. Exercise

Was the Milgram Experiment Ethical or Valid? In 1961‚ Stanley Milgram‚ a psychologist at Yale University‚ conducted an experiment on a group’s obedience to authority. This experiment has encountered intense scrutiny ever since its findings were first published in 1963; many people question the ethics and validity of the experiment. Multitudes of researchers have taken it upon themselves to determine the answers to the questions (McLeod). Based on new guidelines for ethics‚ Stanley Milgram’s experiment
