Answer:
.......is called chemical compound
Answer:
They are secreted from pancreatic cell through exocytosis.
Explanation:
Beta cells of the pancreas are responsible for the synthesis and release of insulin in the blood. Insulin is released in the blood when the blood glucose level reaches above the normal blood glucose level.
Once the beta cells are insulated the insulin is released from the cell by the process of exocytosis and reaches to blood capillaries of islets. Insulin is made up of A and B chain when released in the blood but in proinsulin, a C chain is also present which is released in mature insulin.
Therefore exocytosis is responsible for releasing insulin from the Beta-cell of the pancreas.
Natural selection is when favorable traits stay in a population while unfavorable traits get weaned out. EX: There is terrain that is lightly colored and there are some moths there. They need to blend into the terrain to not be eaten by birds. So, the lighter colored moths live longer and can produce more offspring than the darker colored moths. Now, what happens if the color of the terrain changes due to a factory being put right next to it and causing the terrain to turn grey. The lighter colored moths will be eaten more than the darker colored moths so then he darker colored moths will be reproducing more and most of the moths will be darker colored.
Artificial selection:<span> is the intentional breeding for certain traits, or combinations of traits, over others, and is synonymous with "Selective breeding".
EX: the breading of certain dogs to produce the poodle.
