Why is there a debate as to whether archaea is classified as prokaryotic or eukaryotic
Some prokaryotes, especially archaea, are capable of living in extreme environments, such as deep-sea vents, where temperatures can reach 80°C (176°F). Few organisms can survive at this temperature. What adaptations might archaea possess that allow them to survive in such extreme heat?
Select the choice that identifies the organism described in the following statement: The organism is heterotrophic, has cells with cell walls, and is a eukaryote.
Question 24 options:
a)
Archaea
b)
Fungi
c)
The protist called an amoeba
d)
Plantae
