Summarize the importance of stem cells

Stem cells can become almost any cell in the human body.

Explanation:

This is important because in embryonic development, the body uses stem cells to form each individual part. For example, a single stem cell could become a heart cell, or brain cell, or a blood cell, or more. This is also important for possible treatments. In order to heal damaged or diseased bone tissue, blood stem cells can be taken out of the same person and used to fix the tissue. This allows for a lower rejection rate sense the cells used to fix the tissue were already part of the person's body.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
