the answer to the question isn't <u>D</u> its <u>actually </u><u><em>C.</em></u> just too the test
The best estimate of the population of trout in the lake is 500 individuals.
The low number of tagged trout recaptured may be because the tags slipped off.
This possibility can be reduced if the student used tags that does not slip off easily.
<h3>Mark and recapture method</h3>
The formula for calculating the estimated number of individuals in the population is given as:
where:
- N = estimated Number of individuals in the population
- M = number of individuals captured and Marked
- C = total number Captured the second time (with and without a mark)
- R= number of individuals Recaptured (those with a mark)
Calculating the estimate trout population:
N = (50*40)/4
N = 50
Therefore, the best estimate of the population of trout in the lake is 500 individuals.
The low number of tagged trout recaptured may be because the tags slipped off.
This possibility can be reduced if the student used tags that does not slip off easily.

During respiration, members of the animal kingdom use oxygen and then release carbon dioxide as a waste gas.
Members of the animal kingdom have a respiratory system that is composed of muscles, and airways that functions together to transport air into lungs, and the oxygen is used by cells. Carbon dioxide is also transported away from the cells as a waste gas. Respiration relies on other systems, such as the circulatory system, to transport oxygen and carbon dioxide to and from cells.
