~~**Little Genetics Help PLZ**~~

If a person does one, than we can have all four done soon!!! PLEASE HELP

1.) Please summarize the work of Gregor Mendel and explain its significance to our understaqnding of heredity. Based on his work, how can we use a Punnett square to predict the probability of the genetic make-up of offspring?

2.) How are cells different at the end of meiosis than they were at the beginning? HOw does meiosis maintain a constant number of chromosomes in a species? Account for the wide diversity of phenotypes within a species.

3) How would you relate the function of a cell to its organization as a tissue, organ, and an organ system? How does a cell's surface are to volume ratio limit its size? Summarize the sequence of events of the cell cycle. Note differences between plants and animals. For your own benefit, be as thorough as possible.

4.) WHat role if any do enzymes play i the regulation of the cell cycle? What other factors control or regulate the cell cycle? How are the events in a normal cell cycle different from the events in an abnormal cell cycle such as in the case of cancer? Based on your understanding of the cell cycle, can you list ways of preventing cancer?
