Answer:
Any population in a given environment contains a variety of available, inheritable genetic traits. ... In a population, there is a cause-and-effect relationship between the variation of traits and the probability that specific organisms will be able to survive and reproduce.

Explanation:
The Gross Annual Primary Productivity for the wetland ecosystem is the amount of carbon taken up by the aquatic producers through photosynthesis.
Given that: Net Annual Primary Producer is 8,000 kcal/m2 per year, and respiration by the aquatic producers is 12,000 kcal/m2 per year, using the formula NPP = GPP – Respiration, we can determine the Gross Annual Primary Productivity of the wetland ecosystem.
NNP = 8,000 kcal/m2
Respiration = 12,000 kcal/m2
GPP = x
8,000 = x – 12,000 (NPP = GPP – Respiration)
Solve for x:
x = 8,000 + 12,000
x = 20,000 kcal/m2 per year
GPP = 20,000 kcal/m2 per year
The three phases of signal transduction is (1) reception, (2) transduction, and (3) response. Reception involves the binding of a ligand, may it be a hormone or a neurotransmitter; to a receptor, may it be a membrane receptor, cytosolic receptor, or a nuclear receptor. After binding of the ligand to the receptor, there will be signal transduction of events that will ultimately form a response. For instance, insulin actin on the insulin receptor will trigger a series of events that will increase the transcription of the gene translating for glucose transporters and ultimately, increase the number of glucose transporters embedded in the cell membrane leading to increased glucose uptake in tissues.
Some arteries carry oxygenated blood just as some capillaries do.
Some veins carry deoxygenated blood just like some capillaries do.
