Answer:
(B) It is better for the cell if most molecules are prevented from entering.
I hope this helped at all.
Here's what we know:
10,000 individuals
6,840 individuals have blood type AA
2,860 individuals have blood type AB
300 individuals have blood type BB
AA genotype frequency: 68.4%
AB genotype frequency: 28.6%
BB genotype frequency: 3%
The A allele occurs 6,840 * 2 + 2,860 * 1 = <span>16,540 times, which is a frequency of 82.7%, meaning the B allele occurs 3,460 times, which is a frequency of 17.3%. In the next generation, 3%, or 750, individuals would have blood type BB.</span>
Answer:
Genetic drift decreases the genetic diversity within a specie's population. Genetic drift is a change in the allele frequencies due entirely to random chance and probability and is more likely to affect smaller populations and groups than larger ones. Genetic drift can also play a role in the development of a new species.

Answer:
c. CNS
Explanation:
The Central Nervous System (CNS) is responsible for receiving and transmitting information throughout the body. We can define it with the command center that coordinates the activities of the body. It consists of the brain and spinal cord, which are protected by the skull and spine respectively.
Both structures are reinforced by three connective blades, called meninges. They are: dura mater, arachnoid and pia mater. Between the last two there is a fluid that is responsible for the nutrition of the CNS and the minimization of possible trauma caused by mechanical shocks.
