A Evolution is a change in the gene frequency in a population over generations.Evolution is a change in the gene frequency in a population over generations.
B Evolution is a change in the environmental conditions over a short period of time.Evolution is a change in the environmental conditions over a short period of time.
C Evolution is a change in the phenotypic makeup of a population over generations.Evolution is a change in the phenotypic makeup of a population over generations.
D Evolution is a change in the genetic makeup of an individual over a short period of time.
Answer:
Evolution is change in the heritable traits of biological populations over successive generations.
In genetics, dominant alleles are often represented by capital letters and recessive alleles by lower-case letters. Therefore, the allele for brown eyes can be symbolized as 'B' and the allele for blue eyes as 'b'.
In genetics, capital letters are used to represent dominant alleles, while lower-case letters are used to represent recessive alleles. Therefore, we can use 'B' as the symbol for the dominant brown eye allele and 'b' for the recessive blue eye allele. When both 'B' alleles are present (BB), or when a 'B' and a 'b' allele are present (Bb), the individual will have brown eyes, because 'B' is dominant. However, when both 'b' alleles are present (bb), the individual will have blue eyes, because the blue eye allele can only be expressed when the dominant allele is not present.

B. Blood pressure would increase between heartbeats.
C. Blood flow would be temporarily blocked between heartbeats.
D. Blood volume would increase between heartbeats.
Answer:
The correct answer is option A, Blood pressure would drop during a heartbeat
Explanation:
When the arteries get constrict, the walls of arteries reduces the space/volume with in the arteries which causes blockage for a very minute time period. When the flow is blocked the blood pressure increases, while when the walls are released the pressure reduces but the flow increase.
This process is also refered to as Vasoconstriction and it is a normal process which stabilizes the blood pressure.
