The pups deposit a thick layer of blubber that will protect them and allow them to adapt to the cold.
Answer:
Explanation:
Let's evaluate each choice. Remember we are looking for an event to <em>decrease</em> the genetic variation and population.
A. Yellowstone expanded its borders
- If the park expanded, it's likely the population would increase. There would be more space and resources for the deer.
B. A population of wolves was introduced
- A wolf is a predator that preys on deer. If they were introduced, they would use the deer as a food source and decrease the population.
B seems like a good answer, but let's check the others.
C. The amount of disease in the deer population decreased.
- This would help the deer population. Less disease means fewer deaths and a greater population.
D. More grass and shrubs were planted in Yellowstone
- Deer are herbivores, so grass and shrubs would provide more food. This would keep the deer nourished and healthy, meaning a greater population.
The best answer choice is B: A population of wolves was introduced into Yellowstone National Park

Answer:
The answer is "Photosynthesis creates glucose (sugar) which is used in cellular respiration."
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.
