Answer:
A) nutrient A only
Explanation:
In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.
In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.
Yes, they do eat turkey on thanksgiving unless they don't like the taste of it.
Answer:
C). stop taking vitamin B-6, because he's showing signs and having symptoms of vitamin B-6 toxicity.
Explanation:
Increase amount of vitamin B6 lead to lack of muscle control and coordination causing numbness in the body. walking is also painful and unsteady after the side effects of increase amount of Vitamin B6 appears. High amount of Vitamin B6 can also cause nerve damage due to which coordination of body is also affected.
SO if hands were feeling numb and his walking is unsteady. Based on this information, Sean should immediately stop taking vitamin B-6, because he's showing signs and having symptoms of vitamin B-6 toxicity.

The third one!
Mitosis makes two identical daughter cells (so both are diploid).
Meiosis makes 4 haploid cells (each with half the chromosomes of the original cells)...these are how the gamete cells (sperm/egg) are made.
