Answer: Animals whose body temperature is determined in part by the environment are called “ECTOTHERMS.”
Explanation: They can have quite a high body temperature by taking advantage of external conditions, such as basking in the sun to warm up. Animals, like humans, that control their body temperature internally are called “endothermic
Answer: a. oxygen
Basically what (/the) ETC and oxidative phosphorylation is, is the products of the Krebs cycle being oxidized and oxygen receiving electrons. And when the phosphorylation part of oxidative phosphorylation occurs is when ADP gains its third phosphate group becoming ATP.
Forgive me for this poor response I was trying to be quick and it resulted in this vague and disorganized mess. To properly explain the ETC and oxidative phosphorylation it would be best to start from the beginning and explain all the stages of Aerobic respiration. Then it would be easier to Segway in to this final stage which would definitely take 2-3 descriptive paragraphs to cover.
Answer:
They live in fresh water, marine or soil. They feed off of bacteria and other protozoa.
Explanation:
The answer is: massive stars create a lot of heavier elements. They produce much of the carbon and oxygen which is hugely important for humans and water respectively.
