The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

The cerebellum of the brain‚ the “little brain”‚ is located at the rear of the brainstem. The tissue is folded into itself several times and each layer helps with the organization on the mind. It is clear that the cerebellum has an essential job because over time it has grown‚ by studying fossilized skulls it has been exposed that the cerebellum has increased to three times its size over the past million years. This small lump of tissue was first discussed by Ray S. Snider in an article written

Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes

The testing for the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions.
