Question

A researcher is studying two different populations of dolphins that live in two different oceans. You read the research paper, and it states that the main difference between the populations is the number of individuals in each group. What is the best summary of this finding?
The two populations have the same size and age structure.
This species does not vary in its population size in different areas.
These two populations differ in their location and population size.
The populations are in same areas but differ in population size.

Answer 1

D.  The populations are in same areas but differ in population size.

Good luck! :)

Answer 2

Answer: These two populations differ in their location and population size.

Explanation:

These two populations differ in their location and population size is the correct option. This is because it is already mentioned in the situation that the two populations of dolphins live in different oceans. Also there is difference in the number of members in the population that is there is differnce in population size.
