Answer:
The answer is <em>false</em>.
Explanation:
Although very popular in crime novels and TV shows, microscopic hair analysis isn't as reliable as it may seem. It was widely used during 1950-s and 1960-s as the best test to match a hair sample with the suspect, but modern tests proved it to be wrong. Microscopic analysis can give some information about the hair sample such as origin (human, animal or synthetic fiber), color, pigment distribution... For example, if the hair sample found was brown, and the suspect was black-haired, we could claim that he was Innocent. But if the found hair was black, does that mean that we could be absolutely sure that the suspect is guilty? Of course not, microscopic analysis can not provide evidence for that claim. On the other hand, the best method for matching biological samples, at the present time, is DNA analysis.
Students are investigating the distribution of dandelions using quadrats. The students could during their investigation is they can do the pH test and the effect if it is happening or not.
<h3>What is pH?</h3>
pH is the measurement of the acidity or alkalinity of a substance. PH is a scale that marks from 0 to 12. The substance above 7 is acidic and the substance that is basic comes after 7. 7 is the number for neutral, which is pure water. The pH test is very easy to conduct.
To be sure that pH of the soil will not affect the distribution of dandelions. They first test the pH of the soil.

The correct answer is B. Disruptive.
I disruptive natural selection the extreme values for a phenotype are favored. This causes a disruption in the middle of the graph for phenotype distribution, as there is a selection against the average phenotype, hence the name.
In this case of worms, the longest and the shortest worms are the most present, therefore we can conclude that the natural selection is disruptive and favors both of the extremes (short and long) of the phenotype.
