The correct answer is C. Fermentation makes NAD+ needed to keep glycolysis going. The other options are inaccruate since:
for A: there are types of fermentation that does not produce carbon dioxide like Lactic acid fermentation
for B: many types of fermentation only occurs in the absence of oxygen (anaerobic process)
for B: respiration produces around 36 ATP while fermentation only generates around 2 ATP
Survivorship curve = so, first of all, it's a curve, as in a graph.
It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.
However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.
So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.
