Answer: Blood plays a very important role before cellular respiration. The blood provides oxygenated blood for the aerobic processes that takes place during cellular respiration. Glycolysis, link reaction, Kreb's Cycle and Electron Transport Chain are all the aerobic process of Cellular respiration that requires oxygen. Without blood aerobic cellular respiration cannot occur as the source of oxygen is blood. The blood provides oxygen before cellular respiration. After cellular respiration the waste materials are carried away by blood only.
Hence, blood plays an important role before cellular respiration.
Answer:
D. There was a single transition from aquatic to terrestrial habitats
Explanation:
Based on the molecular differences at the level of DNA sequence and inheritance, the molecular phylogenies show that all land plants are a monophyletic group. This is why it suggests a single transition from aquatic to terrestrial habitats occur.
Not enough ..................
False, because a niche is how one animal uses its habitat- many animals use many different niches
The answer is D
