Glucagon acts on the receptors of the liver cell. The gpcr include a internal signaling in the cell following the heterotrimeric G-proteins dissociates. It activates a pathway that results in the breakdown of glycogen to glucose or the de novo synthesis of glucose in the cells.
Answer:
e. natural selection
Explanation:
The theory of natural selection was coined by Charles Darwin. It is based on the fitness of certain phenotypes to survive changing environments. The difference in phenotypes arises from mutations in the genome due to pressure from the environment [can refer to the cell, interacting cells, population or ecosystem]. These mutations are heritable and become phenotype traits that are common in a surviving population.

The correct answer is protein.
The Recommended Dietary Allowance (RDA) is set by the Food and Nutrition Board of the Institute of Medicine. It represents the average daily level of nutrient intake which is sufficient to meet the needs of nearly all healthy people.
According to the RDA, the daily intake of protein for healthy adults is 0.8 grams per kilogram of body weight.
Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.
