Explanation:
I believe they should not be allowed to use in United States. Since the result reports are not supporting or providing clear information on how it is safe to use, we should not permit its use. Secondly, there are many health threats linked to the use of DDT in world war 2.

Answer;
Central Nervous system
Explanation;
-The body is in a continual state of hunger, which is intermittently relieved by eating.
-The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
-The part of the brain which controls hunger is the Hypothalamus. It is the Main regulatory organ for apetite. It is a section of the brain which is responsible for hormone production. The hormones produced by this area of the brain governs body temperature, thirst, hunger, sleep, mood.
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.
