Answer #1

Ans: The process of altering the pattern of gene expression and thus becoming a cell of a particular type is called cell differentiation. The zygote is a tot potent cell - its daughter cells can become any cell type. During embryonic development, some cells migrate. While, once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

Calcium is a second messenger that is used in numerous cell types in order to control diverse biological processes (ranging from synaptic vesicle fusion, to muscle contraction, egg fertilization, and much more). a) Provide a rationale as to how a single ion such as calcium is able to mediate such diverse responses. In other words—how is it that Ca2+ serves to communicate different signals in neurons, versus muscle cells, versus egg cells, etc.?
