When multiple glaciers start their downward flow from a single point, they create an avalanche. It is a rapid flow of snow down a sloping surface. Hope this answers the question. Have a nice day. Feel free to ask more questions.<span>

Option a is correct bcz zoologist study animals not human.
<span>The Watson-Crick model has the sugar-phosphate backbone on the outside of the double helix of DNA, with the nitrogenous bases in the middle. Pauling's model could not exist in cells, because cells are a water matrix. The sugar-phosphate backbone would repel itself because of the oxygens located around it and the electrons of the atoms would be repelled. The bases would also not be able to stack properly and it would contribute to a lot of instability in the molecule that is meant to be the blueprint of life.</span>
Answer:
b. A change occurs in the environment.
d. Poorly adapted individuals have decreased survivorship.
a. Well-adapted individuals leave more offspring than do poorly adapted
c. Genetic frequencies within the population change.
Explanation:
Genetic variation is the variation in DNA sequences between individuals in a population. Looking at the analogy of the question; there is need to first be a change in the environment. This is being followed by decrease in poorly adapted individuals due to the fact that they wont be able to cope with ambient change in the environment. Therefore, as a result only well- adapted individuals would thrive to leave more offsprings than the poor adapted ones.
As such, Genetic frequencies within the population change with time.
