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.
<u>Answer:</u>
Compound light microsocope.
<u>Explanation:</u>
The compound light microscope utilises sets of lens to get bigger view of the object in steps. It is made up of more that two lens and has its own source of light.
So as to find out the amplification while reviewing a picture with a compound light magnifying lens, take the intensity of the target focal point which is at 4x, 10x or 40x and increase it by the intensity of the eyepiece which is regularly 10x.
In this way, a 10x eyepiece utilized with a 40X target focal point, will create an amplification of 400X. The unaided eye would now be able to see the example at an amplification multiple times more noteworthy thus minuscule subtleties are uncovered.
