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>

Explanation:
I mean, there's plenty of differences between muscle and nerve cells. For one, they serve different functions. Nerve cells react and send stimuli rapidly through action potentials, functioning in the nervous system and allowing the brain to communicate with the rest of the body, while muscle cells allow muscles to move. Another difference is the structure of the cells, with nerve cells having dendrites, axons, and neurotransmitters to assist in the firing of action potentials. You're going to have to be a little more specific, I can't really help you any more with such a broad question.
Answer:
prenatal environments
Explanation:
Depending on the number of fertilized eggs and when the zygote division occurs, there are different types of twins. For example, If the zygote is formed by the union of an ovule and a sperm that after fertilization is divided to create two embryos, they are born identical twins, these babies carry the same genetic information.
Answer:
The "Jaws of Life" is a crucial tool to fire and rescue squads to save hundreds of lives every year. ... The “Jaws of Life” is used indeterminately for pretty much any type of heavy-duty tool that acts like a pair of scissors, cutter, spreader, or ram-device aimed at slicing and dicing through most automotive metals.
Explanation:
Answer:
B. meiosis
Explanation:
Meiosis is the process that produces our gametes. A cell that undergoes meiosis will divide twice resulting into 4 haploid daughter cells.
