Water reabsorption takes place in the cortical collecting duct (CCD) cells, induced by the peptide hormone vasopressin. An increase in 3'5'-cyclic adenosine monophosphate (cAMP) levels in these cells leads to an increasing permeability of the CCD apical membrane to water.
<h3>What is hormones and duct ?</h3>
Your body uses hormones as chemical messengers. They move to tissues or organs through your bloodstream. They affect numerous processes, including growth and development, and work gradually over time. How your body converts food into energy is known as metabolism.
- Ducts are cell-defined passageways that can be used for either secretions or excretions. a gland is an organ that secretes substances in both plants and animals.

A disease rapidly spreading in a highly populated area would be an epidemic.
DNA is important because it is a molecule that encodes the genetic instructions used in the development and functioning of every living thing.
DNA replication is important because cells multiply through replication, and if DNA could not replicate then cell replication would not be possible. This is important for growth and healing.
Without DNA and DNA replication almost all living organisms would not exist.
As the wolves with short hair decreases (because the environment does not encourage their survival), there will be less competition for the food that both would need. The long haired wolf even with a recessive gene, would increase in number.
A might be true but the hair length by itself will not cause the extinction of the entire wolf population.
C is simply not true. Your givens tell you that the long hair are more likely to survive.
B is the answer, for the reason given above.
