The prokaryotes in figure 2 live in extremely hot deep-sea vents. these prokaryotes do not have peptidoglycan in their cell walls. using these clues, you can conclude that these prokaryotes

A. Are classified in the Domain Archaea

Explanation:

Your clues for this is:

Extremely hot

do not have peptidoglycan in the cell walls

These are characteristics of the prokaryotes under the Domain Archaea. These characteristics also differentiate them from the prokaryotes of Domain Bacteria.

Prokaryotes under the Domain Archaea are known for being able to thrive in extreme environments, both hot and cold. They also do not have peptidoglycan in the cell walls, instead they only have S-layers or surface layers.  

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
