Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Two populations of a species of squirrel are isolated from each other. One population is larger in number than the other. A new disease, which is easily spread and extremely contagious, affects both populations at the same time. Which of the following is the best prediction of how the new disease will affect the two populations?
A
The two populations will be equally affected as they are the same species
B
The larger population will be more affected as they have greater genetic variation
C
The smaller population will be more affected as they have less genetic variation
D
The smaller population will not be affected
Explanation: 

Detailed explanation-1: -The two populations will be equally affected, because the ability to trigger an immune response is randomly distributed among all squirrels of that species.

Detailed explanation-2: -A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species.

Detailed explanation-3: -7. Which of the following most likely describes how the interaction between bears and salmon influences nitrogen dynamics in the environment? (A) When bears consume salmon, they leave parts of the carcasses on the ground, which decompose, releasing nitrogen into the environment.
