BIOLOGY LAB REPORT PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide

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

Aim: The objective is to identify specific chemical substances within a cell and to be able to verify the presence or absence of each one in a cell or food substance for future testing. Hypothesis: The identification of each biomolecular chemical substance should be verified successfully‚ as well as determining if it is present or absent in the cell(s). Theoretical Base: A biomolecule is a substance that naturally occurs in living organisms. Biomolecules consist primarily of carbon and hydrogen

to the workings of the human immune system. 8. The ELISA test can also be used to detect antibodies that are produced in response to a specific antigen. Using information about how you completed this ELISA experiment‚ outline a procedure for testing for antibodies in the blood. 9. Explain why in sudden outbreaks‚ it may be better to test for disease antigens rather than for antibodies. The antibodies are there to help and kill of the antigens‚ but don’t contain the whole DNA strand. The

However‚ if the professor were to look at the takers life history and read that the man has survived ten car accidents went to college for eight years and is blind‚ maybe then may he judge how capable this guy is of learning. An important part of "testing" is how the test taker feels. If they are very sick or too confident it will affect their IQ. From personal experience I have learned that the most intelligent people are not the smartest. Two friends of mine Larry and Tony went to high school

necessity to humans for survival‚ whether it be for food‚ clothing‚ etc. However‚ the unnecessary torture of animals through testing is not a necessity for human survival. When it comes to the needless torture of animals that we claim to benefit‚ the animals lives need to be taken into consideration. S. F. Sapontzis gives his theory as to why animals should not be used in testing. To start with‚ animals are not capable of giving their consent to be used as subjects in an experiment. Secondly‚ "experiments

Psychological testing - is a field characterized by the use of samples of behavior in order to assess psychological construct(s)‚ such as cognitive and emotional functioning‚ about a given individual. The technical term for the science behind psychological testing is psychometrics. By samples of behavior‚ one means observations of an individual performing tasks that have usually been prescribed beforehand‚ which often means scores on a test. These responses are often compiled into statistical tables

The test of the Sudan IV solution was changed to Brown paper bag testing‚ which was done by the teacher before the class. 7. The brown paper bags were dried off by the teacher before the class. The remainders and reactions on the dried brown paper bags were examined and observations were recorded. 8. The samples reacted

Theory Testing The theory that was being tested was the Diet Coke and Mentos Geyser. My children wanted to try and see if we could make the Diet Coke shoot out of the top of the bottle like the videos that they had watched on Youtube.com. How the experiment works is you open a package of Mentos and drop the entire package in the Diet Coke as fast as possible. The faster the Mentos drops‚ the more forceful the Diet Coke Geyser will shoot. What should happen is the combination
