Places located near the equator receives more sunlight than those located near one of the poles. This has something to do with the angle and how the sun casts its light. The more that you are at the center, the more direct the sunlight is shining on you. As you go further from the center, the angle of sunlight bends, giving an uneven distribution of sunlight to areas far from the equator. This is why most countries that are located far from the equator experience snow. They receive less sunlight than those who are living in tropical countries.

Answer:
d. Citric acid cycle
Explanation:
The only process in the list that requires the presence of O2 in order to occur is the Citric acid cycle or Krebs cycle. This cycle is part of the aerobic cellular respiration and it occurs only when O2 is available. If there is no oxygen, an alternative process that could happen is fermentation, but this is only carried by some microorganisms and some cells such as muscle cells.
In fact, oxygen is not needed by citric acid cycle but it is by the next step: the electron transport chain. In this chain, oxygen is the final acceptor of electrons, and without oxygen, the Krebs cycle doesn't occur because the final electron transport chain can't be done.
