Answer:
E. glucagon
Explanation:
Bone remodeling is a natural process that takes place in the human body continuously. The process destructs the old and mature portion of the bones and replaces it with the formation of new bones.
The process of bone remodeling is controlled by the hormones and the mechanical stress the bone faces. The hormone which controls the process is the parathyroid hormone and the calcium which is required during the process of synthesis of bones. The factor which is not involved in the process is glucagon.
Thus, glucagon concentration does not affect bone remodeling.
Answer:
The region of the kidney between the capsule and medulla is called the renal cortex. 9
The T12 and L3 vertebrae attach the kidneys to the retro peritoneum.The areas between the renal pyramids are called the renal columns.
Your brain sends signals to your body to release hormones that make you tired. This is done as a routine, and trying to sleep at different times will mess it up.
Hope this helps!

Answer:
C. There is no genetic drift
Explanation:
A population is said to be in genetic equilibrium when the genetic variation of a population remains constant over many generations.
For a population to remain in genetic equilibrium it is necessary that external factors that disturb the equilibrium should not be present.
The external factors that are responsible for disturbing the genetic equilibrium are mutations, non-random mating, genetic drift and gene flow.
Genetic drift occurs when due to a chance event the allele frequency of a population either increases or decreases and this is usually common in small populations.
Thus, genetic drift should not occur so that the population can be in genetic equilibrium.
