The density of a population of living organisms is usually measured in individuals on one square km. In here we have 50 earthworms on an area of 5 square meters, thus we have 10 earthworms on every square meter. In order to get to the result we need to see first how many square meters there are in one square km. One square km has one thousand meters of length and one thousand meters of width so:
1,000 x 1,000 = 1,000,000 km²
Since we established that we have 10 earthworms on every one square meter, we just need to multiply the number of square meters with the amount of earthworms on every square meter:
1,000,000 x 10 = 10,000,000
So we have a density of 10 million earthworms per square km.
Answer:
D. The scientist can determine if the population has lost genetic diversity by comparing sequences of individuals.
I just took the test and I got it wrong but it showed me the right answer
Btw are you in k12 just curious...

What are the control and experimental group in a study?
The control group in a study is the group in which no changes are applied to the group.
In the control group, the variables are kept constant, hence, the control group is also known as the constant group.
The experimental group in a study is the group to which the treatment being studied is applied. The control group receives the treatment of the variable under study.
Hence, the group that receives the drug 911-918 is the experimental group.
