Answer:
C. Proton gradient
Explanation:
During electron transport chain, the electrons are comes from transport chain come from NADH and FADH₂. As electrons are travels down the chain, proton gradient develops across the inner mitochondrial membrane due to accumulation of high proton (H⁺) in the intermembrane space and a lower proton(H⁺) in the matrix. This proton gradient is used to syntheis ATP.
To avoid predators, animals often camouflage. It is an animal adaptation in order to protect themselves from predators. Adelie penguins' predators are white sharks and they have developed coloration similar to the white sharks. That way white sharks will hardly distinguish them from other sharks.
