the acid in lactate acid‚ it interfere with electrical signals in muscles and nerves‚ slows energy reactions‚ and impairs muscle contraction. The burn up we feel in intense exercise is the cause of hydrogen ion. During this experiment(Muscle fatigue lab) it will be seen that after a while of squeezing a small ball there won’t be the same amount of energy that was started with first and you will feel a burn in your arms which makes you feel hurt and don’t do a lot of squeezing; which is called the

The Effect of Osmosis on a Potato Cell October 12th 2012 Osmosis Lab Purpose: The purpose of this lab is to investigate the effects of osmosis on a potato cell as it is immersed for a period of time in solutions of different water concentrations. Hypothesis: If the potato is immersed into the distilled water‚ then it will be the heaviest out of the three. This is because water is at the lower is moving toward the area of higher concentration‚ which in this case is the potato. This

Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side
