Sedimentary and metamorphic rocks?
Answer:
<h2>
Gastrin: stomach,
</h2><h2>
CCK- SI,
</h2><h2>
Insulin- pancreas,
</h2><h2>
Glucagon-pancreas. etc</h2>
Explanation:
1. Gastrin: secreted by stomach stimulating activity of the stomach
,
2. CCK: secreted by SI stimulating secretion of pancreatic enzymes; contraction of gallbladder and pyloric sphincter and inhibitory effects on stomach
3. Secretin: secreted by SI if material entering SI is acidic, triggering secretion of HCO₃-
.
4. Insulin: produced by beta-cells of pancreas and
stimulates storage of glucose in liver and muscle and it causes re-uptake of glucose when blood-sugar is high, lowering blood sugar
5. Glucagon- produced by alpha-cells of pancreas and
it stimulates release of glucose from liver when blood-sugar is low, and results in raising blood sugar.

Answer:
Explanation:
Regarding the HIV cycle, we fear two types of cycles: lytic and lysogenic. In the first mentioned above, the proteins that make up the capsid will replicate. These unite around the nucleic acid molecules, producing new viruses. As a result of this event, lysis occurs, that is, the infected cell breaks down and new bacteriophages are released. Symptoms caused by a virus that reproduces this way in a multicellular organism appear immediately. In this cycle, viruses use the cell's biochemical equipment (ribosome) to make their protein (capsid).
On the other hand, there is another cycle in which the production of viral components is shut down indefinitely. This type of multiplication is called lysogeny or lysogenic cycle and is a well established phenomenon for bacterial viruses. The symptoms caused by a virus that reproduces itself through the lysogenic cycle in a multicellular organism may take time to appear. Diseases caused by lysogenic viruses tend to be incurable, such as AIDS and herpes. For this reason that after this initial symptoms, like flu, is going to disapear and other symptoms of HIV infection will lie dormant for many years.
