Is the slow change in the gene pool of a species or population
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.

Option C would be correct. The organ system can plays many parts at one time. Also, it is the only system listed.
Hope this helps!
