Answer: It shows the evolution of mutations. Throughout the lifetime of animals and humans depending on their way of life and how they life it they will slowly mutate into a different animal to be able to life that way..
Explanation: Example- Whales use to have legs and walked around the earth. But also loved to swim and play in water. Over time they began to adapt and mutate into what we know f whales now. With no legs, they have large fins to help them swim in the oceans.
Basically your answer is Evolution of the Animal
Answer:
3, Matter cannot be created or destroyed, only transformed
Answer: C. Ii & III are correct
II. reduced intracellular ATP.
III. apoptosis or necrosis.
Explanation:
Cytochrome c oxidase controls the last step of food oxidation. Cytochrome c oxidase is an enzyme responsible for electron transfer in the electron transport chain (ETC), it inhibit in slowing down or stopping the ETC.
Consequently, ATP production would be gradually reduced, as the ETC is responsible for the majority of ATP production. This shows option II is correct.
The question starts by stating that cyanide is highly toxic, so this match up with the fact that a large dose would also cause cell death (apoptosis or necrosis). Therefore, option III is also accurate.
Option I: Inhibiting the ETC is consequential as it reduces oxygen demand because electrons would not flow to oxygen, the final electron acceptor.
