Question

question 9
bacteria or archeans can live in:
a ice
b high in the atmosphere
c in thermal vents
d animal intestines
e all of these
10 points
question 10
prokaryotic organisms that eat methane as a food source are most likely to be members of domain _.
a bacteria
b archaea
c eukarya
d archaea or eukarya equally

Explanation:

• Question 9: Bacteria and Archaea are highly adaptable. Psychrophilic bacteria can live in ice. Some bacteria and archaea can be found high in the atmosphere (e.g., in dust particles). Thermophilic archaea and bacteria live in thermal vents. Many bacteria (e.g., gut microbiota) live in animal intestines. So they can live in all the mentioned environments.
• Question 10: Methanotrophic prokaryotes that consume methane are more likely to be Archaea. For example, methanogenic archaea are well - known for their role in methane - related metabolic processes. Bacteria have different metabolic characteristics in general compared to these methane - consuming prokaryotes, and Eukarya are not prokaryotes.

Answer:

• Question 9: E. all of these
• Question 10: B. Archaea
