"The student predicted that the contractile vacuole would contract fewer times in one minute in a solution that had a higher con
centration of salt than that found in typical pond water. This prediction is most likely
(1)correct, because a high concentration of salt in the environment will force water into the cell, causing the contractile vacuole to pump
(2)incorrect, because salt would be entering the cell, and the contractile vacuole would have to pump it out
(3)incorrect, because the concentration of salt in the environment should not affect a cell
(4)correct, because water would be moving out of the cell into the salt solution"

Answer:
Option A , The allele for yellow is dominant to white
Explanation:
It is given that 23 percent of the sheep have white fat and 77 percent have yellow fat.
Thus, it is clear that sheeps with yellow fat is a dominant characteristics.
Usually, the frequency of homozygous recessive allele in a given population is represented by
and here
Frequency of allele for white fat
While frequency of homozygous dominant allele and heterozygous dominant allele is represented by
And here
Allele for yellow fat
Hence, option A is correct.
