If a doctor wanted to run a blood test to determine whether or not a person was immune to the measles virus, would they need to
ki77a [65]

Answer:

The answer is antibodies.

Explanation:

Antigens are the molecules in the body that have the ability of causing an immune response to a disease whereas antibodies are protein molecules that are produced by the cells in the immune system for each specific disease. So if a doctor wanted to find out whether the person is immune to a disease or not by running a blood test, the focus should be on the presence of antibodies.

I hope this answer helps.

Suppose the fictional condition lycanthropy is an autosomal dominant disorder that causes an affected person to have a strong ph
hodyreva [135]

Answer:

Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.  

Explanation:

As you have seen in the question above, lycanthropy is a mutation that is more likely to be established as the supply of male gametes comes from older men. This is because sperm undergo more mitotic cell divisions than eggs, and therefore are at greater risk of developing a spontaneous mutation.

In order for you to understand this, you need to know that eggs (which are female gametes) are produced at once in a woman's body. Thus, cell division is limited and therefore the opportunity for spontaneous mutations to occur is also limited. However, men produce sperm from adolescence to death, creating the need for countless cell divisions, which can develop genetic errors that create spontaneous mutations in gametes.
