there are 9 questions on this test here is 2 the rest are,

Answer 1

1st question-B) chemoautotrophs
Reason: light can't penetrate into hostile habitats like volcanic vents deep in the ocean. The prokaryotic cells there are called chemoautotrophs and produce food through chemosynthesis. A process where chemical energy is used to produce carbohydrates instead of light(photosynthesis)

2nd question- Answer is A
Reason: super bugs are strain of bacteria that don't respond to antibiotics. You can prevent this by using antibiotics only when directed by a physician and only when needed.
