<h2>Answer: How does the Ebola virus infect people?</h2>

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].

Chromosomes often exchange segments of DNA during meiosis. How might this increase the survival of a species?

il63 [147K]

Answer:

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase

My name is Ann [436]

Answer:

The correct option is A

Explanation:

The main adaptation of desert plants is to minimize water loss through their pores and also through the cell walls on their leaves. So the leaves of many desert plants have a thick covering that is coated with a waxy substance that allows them to seal in and protect what moisture they already have.
