What is the difference between hypothesis and law? A hypothesis is a statement‚ put forth on the basis of reasoning‚ about the things that are being studied. A hypothesis is an educated guess based on past scientific studies and previous experiments. It is not just a random guess. Observation is followed by a hypothesis. For example ‘Plants need sunlight to grow’ can be a hypothesis. It is formulated by taking into account all the observations that are know about the phenomenon under investigation

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

{text:bookmark-start} Hypothesis Analysis {text:bookmark-end} Scientific Method is a process that is the basis for scientific inquiry. The scientific method follows a series of steps: identify a problem you would like to solve‚ formulate a hypothesis‚ test the hypothesis‚ collect and analyze the date‚ and make conclusions {text:bookmark-start} (“LabWrite Resources“‚ n.d.) {text:bookmark-end} We will cover and give examples of how the scientific method works throughout this paper.

scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes. Fructose

The activity of an Enzyme is affected by its environmental conditions and changing these factors can alter the overall rate of the reaction. Reaction rates are influenced by external factors such as pH‚ temperature and salt concentration. Different enzymes have different optimum temperatures in which they are most efficient and different pH levels which is ideal for their formation of enzyme-substrate complexes. As the temperature increases‚ there is more movement of molecules and more random collisions

Enzyme Inhibition Many drugs exert their action by inhibition of an enzyme activity in the body. If the activity of an enzyme is vital to the cell or organism‚ then inhibition may lead to death of the cell or organism. It is now possible to design new drugs which are enzyme inhibitors once a target enzyme has been identified. Types of Inhibitors A) Reversible Inhibitors: The effect of the inhibitor is instantaneous‚ and it can be removed from the enzyme by dialysis so that the enzyme activity

points out directly into the hypothesis. Hypothesis: A research hypothesis can stand for a test of time‚ it must be testable‚ talks about the current knowledge‚ and also realistic. "A hypothesis is a logical supposition‚ a reasonable guess‚ an educated conjecture. It provides a tentative explanation for a phenomenon under investigation." (Leedy and Ormrod‚ 2001). A hypothesis is important because it guides the research. A researcher may refer to the hypothesis to direct his or her thought

control which is modulated through the nigro-striatal system‚ a role in behavior which is modulated through the mesolimbic and mesocortical systems‚ and a role in endocrine control which is modulated through the tuberoinfundibular system. The dopamine hypothesis of schizophrenia states that psychosis occurs when there is too much dopamine in the brain. This occurs through its role in the mesocortical system. There is much evidence to support this theory. For example‚ as mentioned previously‚ illegal drug

Hypothesis Testing: Alzheimer ’s Disease Natalie Sullivan PSY/315 August 8‚ 2011 Deborah Suzzane Ph.D. Hypothesis Testing: Alzheimer ’s Disease One in eight American’s over age 65 are diagnosed with Alzheimer’s disease. This number continues to grow as the population increases. The number of people affected by Alzheimer’s is alarming. The Alzheimer’s Association (2011) estimates that 5.4 million Americans of all ages suffer from this disease. Team A will attempt to form a hypothesis stating

The first hypothesis was homophobic men are more sexually aroused to homosexual signs then non-homophobic men. The second hypothesis was homophobic men are more hostile or aggressive than non-homophobic men. 2) Did the results of the study support or refute the researchers’ first hypothesis/prediction?
