Question

Archebacteria are known as extremophiles, Which one of the following justifies this statement?
A) Archebacteria can prepare their food using photosynthesis unlike eubacteria
B) Archebacteria can cause extremely severe diseases in humans, unlike eubacteria
C) Archebacteria can surive in extreme conditions, including without sunlight and oxygen, unlike the eubacteria

Answer 1

Your answer should become more obvious once the term 'extremophile' is explained. 'Extremophile' (meaning "extreme lover") is a term used to describe an organism that can thrive in impossible, or 'extreme' conditions. An example? Some types of bacteria can survive in boiling hot temperatures that would kill humans and other complex organisms. Some can live in climates with temperatures many, many, many, degrees below zero. I hope this cleared it up for you! :)

Answer 3

@Pachelbelia - for future reference, with multiple choice questions like this one - try to explain the question and encourage the asker to work through it (as @tafkas77 did) rather than giving the asker the answer directly :) this way the asker is benefited more in the long term!
