8 0

So by looking at the seismic waves from earthquakes the scientist learned about the crust and the mantle but they also learned about the outer and inner core. To do this you have to look at a different kind of waves, the S (secondary waves) waves that also get released by an earthquake.

<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>

There are 2,000 mice living in a field. If 1,000 mice are born each month and 200 mice die each month, what is the per capita gr

Ivan

For 2,000 mice living in a field, the per capita growth rate is mathematically given as

NT=0.4

<h3>What is the per capita growth rate (rmax) of mice over a month?</h3>

Generally, the birth and death rate is mathematically given as

BT=1000/2000

BT=0.5

Where

DT=200/2000

DT=0.1

In conclusion, per capita growth rate

NT=0.5-0.1

NT=0.4
