Question

2. Which of the following can survive either with oxygen or without it?

obligate aerobes obligate anaerobes facultative anaerobes bacteriophages
3. Where are you likely to find a photoautotroph?
in your refrigerator in the deepest parts of the ocean in your digestive system near the surfaces of lakes and streams
4. During what process do prokaryotes exchange genetic information? (1 point)
cell division binary fission conjugation endospore formation
5. What would be a direct consequence of the disappearance of nitrogen-fixing prokaryotes?
Dead organisms

Answer 1

Since the other guy did not answer number 5 the answer to your question is

Organisms would not be able to get the nutrients they need to make proteins.

Answer 2

2.Facultative anaerobes can survive either with oxygen or without it. This organism can live and grow in the absence of oxygen. The correct answer is:

Facultative anaerobes

3.Photoautotroph are organisms that carry out photosynthesis. The place where you are likely to find a photoautotroph is near the surface of lakes, streams, and oceans. The correct answer is:

Near the surfaces of lakes and streams

4.Prokaryotes are the smallest and most abundant organisms on the Earth. They range in size from 1 to 5 micrometers. This organisms are classified as Bacteria or Archaea. Most of them exchange genetic information by a process called conjugation. The correct answer is:

Conjugation

I hope it helps, Regards.
