Both Gradualism and punctuated equilibrium are explanations of the rate of evolutionary change. Therefore, the correct answer is A
Gradualism and equilibrium are two different ways in which the evolution of species can take place.
<h2>Further Explanation</h2>
Gradualism is a variation that occurs gradually and can be cannot be recognized easily over a short period. Evidence of gradualism has been found by scientists in the geologic process. Scientists describe gradualism as some of the processes that are going on in earth’s landforms and surfaces. They also pointed out that the mechanisms it contained, erosion, plate tectonics combines the processes that in some aspects appear destructive and others constructive.
Punctuated equilibrium, on the other hand, has to do with the notion that since no changes can be seen in a species, there must however be a period when no changes take place. Punctuated equilibrium maintains that evolution happen in a short burst with a longer period of equilibrium.
One of the scientists that proposed punctuated equilibrium is William Bateson, he argued that species can only evolve rapidly and not gradually. He believed that evolution occurs rapidly in a species with a long period of stability.
Thus, Both Gradualism and punctuated equilibrium are explanations of the rate of evolutionary change. Both are accepted ideas of how evolution occurs in a species.

Hello! The correct answer for the blank is: Placenta.
I hope this helped you! c:
Answer: 1. Plucking
2.Moraine
3. Kettle lake
Plucking is a process of erosion in glacier in which rocks and sediments are displaced by the glacier to other locations. These rocks and sediments gets freeze at the bottom of the glacier.
A moraine is a sediment deposited by a glacier. This may be in a form of thick layer of sediment called as ground moraine or a small ridge of deposits called as end moraine.
A kettle lake is formed when ice in large extent gets melted and this results in formation of depression which is called as kettle. The kettle is filled by melted water forming a lake or kettle lake.
