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:
The correct answer is All of the above are correct.
Explanation:
Earth is very diverse which contains microscopic organism to huge organisms like blue whales. Some live in water, some live on land and some live in extream climates. But there is something which unites every organism on this earth as every organism is evolved from a single individual.
Therefore there is unity in diversity seen at many stages in living organisms like structure of DNA is same in all organisms, every organism contains the same genetic code for a particular amino acid, forelimbs of all mammals have the same basic structure and evolved for different functions.
These all are the examples of unity in diversity so the correct answer is all of the above.
The correct choice from given option is <span>"B", "Lactobacillus"</span><span>
It seems proper to explain a bit about the types of cells here. </span>Two type of cells are:
1) Prokaryotic: these
cells have no nucleus and they are small and simple.
2) Eukaryotic: These cells have a nucleus and are large and complex as
opposed to prokaryotic.
<span>"Lactobacillus" belong to first stated category
here.</span>
