Answer:
be heritable and be an advantage to offspring
Answer:
p = 20
Explanation:
to get p alone you have to do the oposite of what your doing with p
ex) its being divided so you would have to multiply both sides by 4 to get p alone
p = 5x4
<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.
The embryonic stem in a seed is the plumule.
it grows out of the hypocotyl, which that itself grows out of the radical, which is attached to the microphyl, feeds on the cotyledon, is fertilized by the endosperm, and is all protected by a hard seed coat :)
