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.
<span>Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.<span>

The answer which is not an example of a structural adaptation in plants is B. roots that grow in the direction of a water source.
This is the case with any plant, so it's not really a form of adaptation, whereas other options are.
