The hormone primarily responsible for contraction of the gallbladder and release of bile into the duodenum is?
The hormone primarily responsible for the contraction of the gallbladder and the release of bile into the duodenum is cholecystokinin.
Cholecystokinin also called pancreozymins is produced in the duodenum which is a part of the small intestine by the cells known as enteroendocrine cells and its secretion is stimulated by the introduction of fatty acids and amino acids. This hormone is involved in the process of digestion.
Cholecystokinin causes the contraction of the gallbladder which then releases bile and enzymes into the small intestine. Bile salts and other enzymes are involved in the breakdown of fats and proteins so that they can be absorbed in the small intestine. During the digestion process, this hormone also slows down gastric emptying and controls bowel motility.

Which of the various species concepts distinguishes two species based on the degree of genetic exchange between their gene pools?
The biological species concept distinguishes two species based on the degree of genetic exchange between their gene pools.
What is biological species concept?
A species taxon is a collection of creatures that may effectively interbreed and give birth to fertile offspring, according to the Biological Species Concept. That idea holds that both interbreeding within a species and reproductive barriers between creatures of various species help to protect the integrity of a species.
The biological species concept (BSC) was created to help people understand biological diversity, notably the widely acknowledged finding that sexually reproducing organisms are more likely to be found in genetic and phenotypic clusters than in a continuum of forms.

The na glucose symporter is an example of _____ transport, and it is found only on ______.
The na glucose symporter is an example of active transport, and it is found only on epithelial cells.
A transmembrane protein known as na glucose symporter is a sort of sodium-driven secondary active transport that occurs in the epithelial cells of the small intestine. The sodium-glucose symporter is found in the apical membrane of epithelial cells. The symporter binds to sodium and glucose, which are subsequently co-transported into the epithelial cells simultaneously. The sodium-driven glucose symporter utilizes the potential free energy stored in the sodium electrochemical gradient (low sodium concentration inside epithelial cells) generated by the Sodium-Keto pump. As a result, sodium influx from the lumen to the epithelial cell is connected to glucose transport (symport).
