For glaciation to begin, something needs to cause Earth's temperatures to drop. If this happens, snow that falls on the polar ice caps does not melt, and glaciers grow. As snow and ice reflect sunlight, the Earth's temperature is reduced even further, causing glaciers to continue growing.
Sea level changes cause marine transgressions and regressions. During a marine transgression, the shoreline moves inland, leaving sedimentary deposits that contain fossils. The shoreline retreats during a marine regression, leaving behind the deposited sediments.
Explanation:
Algae living on a sloth is considered an example of mutualism because both of them benefit from each other.
Mutualism is one of the symbiotic relationships in which both the two species living together benefit in one way or another. A considerable example of such a relationship is between algae and a sloth.
The algae provide camouflage to the sloth and protect it from predators while the sloth provides shelter to the algae for its growth. The sloth also gets nutrition from algae which perform photosynthesis and synthesize food.
Another mutual relationship is observed between the aphids and ants. Aphids produce honeydew as a waste product of their diet which is consumed by ants. While ants protect the aphids from predators and parasites.

Answer:
The correct answer is B.
Explanation:
Given the baltimore's scheme which used for virus classifications, the most closely related option of virus to the described polio virus with a single stranded RNA in the question would be retroviruses that require a DNA intermediate.
Because much like the single-stranded RNA viruses, the retroviruses do not contain any DNA but they do have an enzyme named reverse transcriptase which they can use to replicate their RNA into the host cells DNA and use the end product for their benefits. So they both work in similar ways.
I hope this answer helps.
