Which phrase best describes osmosis? A. the process where DNA is created B. the movement of molecules through the cell membrane
kirza4 [7]

The answer is; D. The movement of water molecules from an area of high concentration to an area of low concentration

A is not correct because Osmosis does not create DNA.

B is incorrect because the movement of molecules through the cell membrane is called Passive Transport.

C is incorrect because the division process of the cell's cytoplasm is called Mitosis.

<u>Thus brings us to </u><u>D </u><u>which is the correct answer because Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient.</u>

One way to determine the density of animals in an area is to use the mark-recapture technique. A number of individuals from a po
NNADVOKAT [17]

Answer:

N = 187.55

Explanation:

Here you just need to replace the terms and clear the equation.

You already know that,

  • First capture: 25 prairie dogs.
  • First marked animals: 25 (the whole first capture)

You let these animals leave and then you made another capture.

  • Second capture: 135 prairie dogs
  • Already Marked animals: 18 (these 18 dogs were caught in the first capture and marked before releasing them)  

To know the size of the prairie dogs population you just need to use the following equation and clear N, which is the value that you are looking for.  

Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch

  • Number of individual marked in first catch = 25 dogs
  • Total population size, N = this is what we want to know
  • Number of individual marked in 2nd catch = 18 dogs
  • Total number of 2nd catch = 135 dogs

So now, we need to replace terms

25 / N = 18 / 135

25 / N = 0.1333

N = 25 / 0.1333

N = 187.55
