Bacteria consist of only a single cell, but don't let their small size and seeming simplicity fool you.

Details an experiment examining the yeast activity with the change of temperature in anaerobic respiration. Concludes that because the anaerobic respiration, the yeast had produce Carbon Dioxide so the lime water that was in the beaker will turn now milky.

This disease affects some humans also, but is mostly spread to racing greyhounds and pit bulls. There is more than 100 different kinds of the Babesia disease but it is most common in the USA. Babesia goes to the red blood cells and infects them. What happens after that is then the cells start to divide and burst after it synthesizes with the DNA and then it goes and effects new red blood cells. This disease is very harmful to the animal or person. Its symptoms are weakness, jaundice, fever, loss of appetite, muscle aches, chills, and red or orange colored urine.
