Answer:
D. None of the above
Explanation:
<u>Reason that Drastic Change in weather may cause mass extinction</u>
Weather plays an important role in the survivability & the growth/diminish of the population. For example, animals that need large amounts/bodies of water (for example fishes), will not survive when the area is hit with a heat wave & drought, which would cause fishes to surface, and die.
<u>Reason that Geological change would play a large role in mass extinctions</u>
While the Geography is constantly changing, large abrupt changes would cause a upheaval and may upset the population, leading to a depletion of resources or even a sudden destruction of part/all of the population. For example, an earthquake may kill large amounts of animals, and the destruction of the greenery in the area may severely limit the amount of food/decrease the primary consumer's populations, leading to a starvation.

Answer:
In the animal cell the organelles that is labelled G is mitochondria.
Explanation:
Mitochondria are the membrane bound organelles with inner membranes folded inside which can form finger like structures called cristae. There numbers are more in the cell. They are basically responsible for the production of the energy, hence called as the power house of the cell. They also perform the cellular respiration, which means it takes the nutrients from the cell breaks it and makes energy from it. This energy is used by the cell to carry out various life processes.
The arrows usually point to the organisms that are doing the eating.
Explanation:
For that reason, we can say that the arrows represent the flow or transfer of energy in an ecosystem. It also specifies the direction of the flow of energy.
Six thousand reindeer once lived on a remote island in the Bering Sea
that was briefly their paradise. In what has become a classic story of
wildlife boom and bust, no reindeer live on St. Matthew Island now.
Three scientists just looked back at the St. Matthew's reindeer herd and
found that an extreme winter probably pushed the stressed animals to
their deaths.
C. The presence of predators could cause natural selection because it would mean survival of the fittest.
