How are stem cells different from other cells in an adult animal?

Answers

Answer 1

Answer: Stem cells aren't differentiated cells. A fetus starts as a bunch of cells that are destined to become cells of the body. Some cells will eventually be led to express the proteins to become skill. Others will become muscle, other bones, etc, etc. Thus they will be differentiated into skin, muscle, bone, etc. However, there are many levels of differentiation. Fetal stem cells for example can become programmed to become anything, whereas adult stem cells may be partially differentiated so that they may become a set of cells. For example, connective tissue stem cells can be told by the body to become skin, fat, tendon, etc.

Answer 2

Answer: Stem cells are unspecialized cells that are, for lack of a better term, waiting for a job. Other cells, somatic cells and sex cells, have already been specialized, and work together as a tissue.

describe a day in the life of a chromosome. Please include descriptions of the processes of independent assortment, crossing over, and mutations.

Answers

Well, it is quite a large topic, so you have to resolve it yourself, but I can give you some tips how to organize your essay and how to start. At first, just write it like a diary note, make an introduction with name and add the ''chromosome'' to your name. Then just check on the Internet all the processes you need to include and rewrite it in the informal way, describing each of them like you feel it. To make it easier, divide your text on pharagraphs where each one refers to particular process. Use your imagination!
