Answer: <u><em>
How does the Ebola virus infect people?</em></u></h2>
<em><u>Ebola virus contains a type of genetic material called RNA, which is similar to DNA and contains the blueprint for assembling new virus particles. Unlike animals and plants, which also use DNA as a repository of information, viruses are not technically alive because they are incapable of replicating without help. In order to create new viruses, the virus must infiltrate a living cell, where it hijacks the host cell’s machinery to fulfill its own goals. In order to get into the cell, Ebola must travel through the cell membrane, which is a barrier that protects the cell from its environment. However, all cells need nutrients, which must have ways of entering the cell; the viruses hitch a ride into the cell via one of these established nutrient-uptake entryways. Ebola virus takes advantage of a non-specific engulfing process called macropinocytosis, which allows the virus to be “eaten” by a wave-like motion of the cell membrane (Figure 1) [2].</u></em>

Answer:
Pia mater
Explanation:
Three meninges cover the brain and spinal cord. Pia mater refers to the deepest meninx of the brain. It is a thin delicate layer of connective tissue. It is a transparent connective tissue layer like that of cellophane. Being a transparent and thin tissue layer, it looks like a cellophane wrap adhered to the surface of the brain.
When limiting factors increase, diversity in populations decreases. In this sense "limiting factors" can be anything from a lack of resources to a lack of food, meaning it's harder for the population to survive.
