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

4. Which material dissolves<br> most substances in chemical<br> weathering?
Assoli18 [71]

Answer:

Water is important in chemical weathering because most substances dissolve in water.

The process of dissolving breaks up the minerals in the rock into small pieces. The small pieces mix with water to form.  

Acids are also agents of chemical weathering and cause more chemical weathering than pure water does.
