Answer:
The flu virus mutates
Explanation:
We need a new vaccine for each new strand of a flu virus
1. The percent probability that the first child of the couple will have Huntington's disease is 50%
2. The percent probability that four of the seven children will have Huntington's disease is 6.25%
<h3>Genetical probabilities</h3>
The disease is autosomal dominant. Only one dominant allele is needed for the disease to be manifested.
The husband is Hh and the wife is hh.
Hh x hh
Hh Hh hh hh
Hh (affected) = 1/2
hh (unaffected) = 1/2
1. Probability that the first child of this couple will have Huntington's disease is the same as the probability of having the disease. Thus, it is 1/2 (50%)
2. Probability that four of the seven children will have Huntington's disease is the same as the probability of having the disease in 4 places.
1/2 x 1/2 x 1/2 x 1/2 = 1/16 or 6.25%

#SPJ1
Corn, believe it or not, is indeed a type of grass. It has been selectively bred, and genetically engineered to produce large ears of corn.
The cell cycle involves the growth, replication, and division of a eukaryotic cell. Mitosis most directly plays a role in the division of a cell's nucleus.
Mitosis is the process that takes place in the somatic cells or the body cells, where the diploid cells divides to yield two diploid daughter cells. The process occurs in five stages which includes; interphase, prophase, metaphase, anaphase and telophase.
The answer is B only because it makes wayyy more sense
