In response to c. acid in duodenum, the hormone secretin is released by endocrine cells in the duodenal mucosa.
<h3>What releases secretin in the duodenum?</h3>
Secretin is a polypeptide that contains 27 amino acids. In response to H+ and fatty acids in the lumen, S cells in the duodenum produce secretin. Particularly, a pH of less than 4.5 indicates the entry of stomach contents, which starts the secretin release.
Secretin, a digestive hormone that controls gastric acid secretion and pH levels in the duodenum, is released by the wall of the upper portion of the small intestine (the duodenum).
A pancreatic fluid that is high in bicarbonate is secreted when secretin is present (45). By interacting with pancreatic ductal cells, secretin enters the bloodstream or intestinal lumen and increases the production of bicarbonate, which lowers the pH of the gastric chyme as it enters the small intestine.

I think that Chromosome is to tree as gene is to Leaves? Is it a multiple choice because you should give options out of all characteristics of a tree.
The lower parts of the brain function primarily in Survival, whereas the outer layer of the brain functions mainly in thought. The medulla oblongata is the lower half of the brainstem continuous with the spinal cord. The medulla contains the cardiac, respiratory, vomiting and vosomotor centres dealing with heart rate, breathing and blood pressure. The outer layer which is the space between the two hemispheres is the longitudinal fissure. The corpus callosum connects two sides and transfers signals from one side of the brain to another.
A phylogenetic tree<u> uses only 1 and 2 </u> whereas a cladogram does not. The group of answer choices includes the dimension of time indicates ancestral-descendant relationships use analogous character traits all of these.
A phylogenetic tree is a bifurcation diagram used to explain scientists' hypotheses about how branching between evolutionary lines occurred.
The most recent common ancestor of two taxa is the node that represents the fork between those taxa. In this case, the letter b represents the turning point between the gorilla and the human.
A phylogenetic tree is a bifurcation diagram showing putative relationships between different species based on similarities and differences in physical and/or genetic characteristics.
