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

pulation are captured, marked so they are easily identifiable, and released back into the population. It's assumed that the captured and marked animals will randomly mingle with the rest of the population. Later, the population is re-sampled and the number of marked and unmarked animals is recorded. The following equation can then be used to estimate the size of the entire population.
Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch

If 25 Prairie Dogs were captured, marked, and released back into their population, and then subsequently 135 Prairie Dogs were captured, of which 18 were marked, what is the approximate total population size, N?

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

Glucose moves from the plasma into a skeletal muscle cell, where it is used for energy. Through which fluid compartment does glu
Tanzania [10]

Answer:

(B) Interstitial fluid

Explanation:

The interstitial fluid and blood plasma together make the extracellular fluid. The extracellular fluids are present outside the cells. The extracellular fluid that is present in the narrow spaces between cells of tissues is known as interstitial fluid. When a substance moves from blood plasma into the cells of a tissue, it crosses the interstitial fluid present between its cells. Therefore, when a skeletal muscle cell picks glucose molecules from blood plasma, it moves from plasma to the interstitial fluid to enter the cell.

What is the difference between chimerism and mosaicism? Please explain it in details
GrogVix [38]

Answer:

The outcome of cell‐lineage competition is likely to depend, among other factors, on the initial number of cells involved. Mosaicism generally starts as one or a small group of mutant cells while chimerism generally involves a more massive input of genetically different cells
