Answer:
A. will not change from generation to generation.
Explanation:
For a population in the Hardy-Weinberg equilibrium, allele frequencies do not change from generation to generation and remain constant. This occurs when:
-The population is large enough.
-Individuals of the population exhibit random mating
.
-No evolutionary force (natural selection, mutation, gene flow, etc.) is operative on the population.
Under these conditions, the allele frequencies of the population are not changed and the population is said to be in "Hardy-Weinberg equilibrium".
Answer: The Parathyroid gland
Explanation:
The Parathyroid gland secretes "Parathormone", an hormone that exerts
- direct influence on the bone by INCREASING the release of bone calcium ion (Ca2+) into the blood
- affects the kidney by stimulating the renal tubules to eliminate EXCESS calcium in the urine.
Thus, the calcium balance of the body depends on the secretion of the Parathyroid gland
