Answer:
A
Explanation:
Archaebacteria, meaning “old bacteria,” are grouped like that because of DNA differences and because they live in extreme environments, like salty, very hot, or very cold.
Eubacteria, meaning “true bacteria,” are grouped separately from archaebacteria because they do not exhibit those traits. Living in extreme environments is a characteristic of archaea.
Why not B: this describes archaebacteria.
Why not C: bacteria are unicellular, though they can aggregate into groups.
Why not D: they can be anaerobic or aerobic (use oxygen).
Enzymes are catalysts, meaning that they are proteins that speed up reactions. So without them, there would be barely any activity.
Scorpions are carnivores as they attack and paralyze their prey by stinging them with its tail. Depending on the scorpion's size, they eat from the smallest of insects like cockroaches and crickets to larger creatures like mice, small rabbits, and birds.
Not the same and they is not in a relationship
