This observation can be explained by the theory of endosymbiosis. From what scientists have discovered, it can be explained that the double membrane of both chloroplast and mitochondria are as a result of them been subjected to phagocytosis but they were not digested. Their DNA suggest that they were once free living prokaryotes. This agree with the endosymbiosis theory which states that eukaryotic cell organelles developed from prokaryotic cells.

Why does it benefit an imperial shrimp to travel on a sea cucumber?
olasank [31]

Answer:

the imperial shrimp and the sea cucumber have what's referred to as a one sided symbiotic relationship. that's a type of relationship where there's two organisms, but only one of those organisms benefit. the other organism isn't helped, but it isn't hurt, either.

<u>an imperial shrimp benefits from its relationship with the sea cucumber because the shrimp, when hungry, can get a lift on his lil friend the sea cucumber and is dragged around the ocean to where there's food for shrimp to eat :)</u>

UkoKoshka [18]

B.  New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.

Explanation:

The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.

Cellular respiration is classified as an catabolic  process in which an energy rich substance is broken down into a lesser one.

  • Metabolic processes are usually divided into catabolic and anabolic processes.
  • In catabolic step, energy is broken down.
  • Cellular respiration is catabolic whereas photosynthesis is anabolic.
  • The new compounds formed have lower energy bonds after respiration.
