Answer:
B. glucose – NADH – electron transport – O2
Explanation:
This is the sequence from glycolysis in which glucose molecules are split down to pyruvate, to oxidative phosphorylation.
During this process the electrons are released from glucose molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .
The makes the carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .
The electrons from above are transferred in hydrogen atoms to matrix by these co-enzymes.Where the H is split to electrons and protons.
The electrons for the ETC, produce the PMF for transporting protons into the intramembrane space.
The concentration of protons generated the electrochemical gradients which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.
The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.

Answer:
emigration
Explanation:
The emigration of an animal, in this case of the antelope, is the cause of the lack of food.
The animals are in constant search of food and better places to cohabitate. Antelope is leaving its herd to find a better place for food and even if it sounds strange, animals are also behaving as individuals in case there is threatening of hunger.
