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

In the Southern Colonies‚ slaves were widely used as a source of cheap labor for plantation owners that wanted cheap labor. Slaves were subjected to harsh conditions‚ working long work days in extreme heat in horrible working conditions. They were used to grow and harvest tobacco‚ sugar‚ and rice on plantations. Slaves were widely used in the South‚ in contrast to the North‚ who had slaves‚ but not nearly as many. Slaves were used in the South because there was an economic need‚ it was cheaper for

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

Over time‚ the English gained control of the thirteen colonies through force or purchase; eventually‚ by regions were known as the Southern‚ Middle and New England colonies. Although the colonies were under the control of the English and

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some days for the seed to germinate before planting. The corn was growing there were
