Explanation / Answer
14. The answer is C. elemental sulfur.
If cyanobacteria are photosynthesizing with sulphide then the byproduct is elemental sulfur.
15. The answer is: B. endosymbiotic chemilithotrophs in their trophosome.
These bacteria converts carbon dioxide to organic materials and supply to the tube worm.
16. The answer is: D. All of these.
Oxygen is used by the bioluminent vibrio species to perform aerobic respiration, to produce light as well as for luciferase activity.
17. The answer is: D. Only in the plants
These genes are active only in the plant.
