The correct answer is: D) secretin
Gastric secretion is highly regulated whether its secretion should be increased (when food is eaten) or decresed (as the stomach empties). Secretion is controlled by the nervous system and endocrine system that work together. There are three phases of gastric secretory control:
Cephalic-by the brain
Gastric-by the stomach itself
Intestinal- by the small intestine
All of three can work simultaneously.
Secretin is released by duodenal enteroendocrine cells and it stimulates the pancreas and gall bladder, but also suppresss gastric secretion and motility. Secretion of the secretin is stimulated by the chime and it is the part of intestinal phase.
Answer:
missense
Explanation:
missense: alteration of one or more codons so that different amino acids are determined
silent mutation: mutations in DNA that do not have an observable effect on the organism's phenotype
Answer:
Explanation:
Mutualism - two organisms that benefit from each other
Commensalism - one organism benefits, one isn't harmed
Parasitism - a parasite benefits from and harms a host
Predator-Prey - a predator (animal that kills another for food) kills a prey (the animal it likes to eat) and eats it
The body can only synthesize 11 of the 20 amino acids, all other nine needs to be incorporate with food and those are the ones that we call essential amino acids.
Most of the metabolic cycles use carbon coming from glycolysis, the pentose phosphate pathway or the Krebs cycle.
