It is much easier for a small animal to run uphill than for a large animal,because

Choose the correct statements:
$(i)$ The complete combustion of glucose,which produces $CO_2$ and $H_2O$ as end products,yields energy,most of which is given out as heat.
$(ii)$ The scheme of glycolysis was given by Gustav Embden,Otto Meyerhof,and $J$. Parnas and is often referred to as the $EMP$ pathway.
$(iii)$ In glycolysis,$ATP$ is utilised at $2$ steps,not $4$.
$(iv)$ In both lactic acid and alcohol fermentation,not much energy is released; less than $7$ percent of the energy in glucose is released and not all of it is trapped as high-energy bonds of $ATP$.
$(v)$ For aerobic respiration to take place within the mitochondria,the final product of glycolysis,pyruvate,is transported from the cytoplasm into the mitochondria.

In the terrestrial habitat,which of the following factors affect temperature and rainfall conditions?

In the hexose monophosphate shunt ($HMP$ shunt),the number of $CO_2$ molecules evolved is:
