Hydronium Concentration of Water and its Effect on Fast Plant Growth

Case study - 4 pages - Biology

Acid rain has always been said to damage the plant life which absorbs the acid water as it would regular water. In this experiment we have decided to see whether this is true and if acid content of water has any effect on plant growth. We have setup an experiment and predict that pH will affect...

Cardiovascular lab report focusing on Amphibian Heart

Essay - 5 pages - Biology

The heart is an integral part of the cardiovascular system in the body of vertebrates. It provides the pressure needed for the blood to be pumped to different parts of the body. The heart maintains the flow of blood throughout the whole cardiovascular system. This in turn allows all the separate...
