The correct answer is d. 3.5 billion years.

Prokaryotes were the first forms of life on Earth long before simple multicellular life appeared because of their ability to withstand extreme conditions. It is believed that the first living forms were bacteria combined with archaea in the microbial mat (multi-layered sheet).

<h2>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>
