r If a mouse population changes color from white to black over many generations, which question should be asked to determine whether the population changes are a result of natural selection or artificial selection?
A.
What do humans need to keep mice healthy as pets?
B.
Was there a change in the genetic traits of the mice?
C.
Were the genes of the mice inherited from their parents?
D.
Was there a change in the environment where the mice live?
Answer:
D if there is a change in environment that would favor black fur you could assume that natural selection caused the fur to change
Explanation:
The question which should be asked to determine whether the population changes are a result of natural selection or artificial selection is that was there a change in the environment where the mice live? Thus, the correct option is D.
Natural selection is the process through which the populations of different living organisms adapt and change with respect to their surrounding environment. Individuals in a population are naturally variable, it means that they are all different in some way or the other. This variation in the population means that some individuals have traits which are better suited to the surrounding environment than others.
If a mouse population changes its color from white to black over many generations, then the question which should be asked is "Was there a change in the environment where the mice live?"
Therefore, the correct option is D.

Answer: DNA and proteins contained in the nucleus, known as chromatin, condenses. ... The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.

Answer:
Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. ... A force has both magnitude and direction, making it a vector quantity.
