Answer:
c.) loss of chloroplasts
Explanation:
Chloroplasts are the double membrane-bound organelles of photosynthetic eukaryotes and serve as the site for photosynthesis. The organisms that can carry out photosynthesis make the organic nutrients and do not depend on other organisms for food.
According to the given information, the photosynthetic protists become parasite in fish and start deriving nutrition from the host. If the protists continue to survive as a parasite to fish, the chloroplasts will be rendered non-significant. The parasitic mode of nutrition does not require chloroplasts and therefore, the protists would lose the organelles over generations.
Answer:
here.
Explanation:
17. antibiotics
18. reproduction (growth is increase in size and number)
19. cell walls (like penicillin. This mechanism is important because it will not harm the host as human cells don't have cell walls.)
20. 70S ribosomes (because this is where protein synthesis occurs in bacteria)
They need energy to produce oxygen
