Question

A biologist examines a single-celled organism isolated from a hot spring. The organism is a photosynthetic halophile that uses the pigment bacteriorhodopsin. In which kingdom should the biologist classify the organism?A. BacteriaB. ProtistaC. FungiD. Archaea

Answer 1

Answer:

(D). Archaea.

Explanation:

Archaea are single-celled, prokaryotic organisms that can survive in extreme conditions. Archaea that live in environments with extreme salt concentrations are known as halophiles.

Archaea use bacteriorhodopsin, a protein which helps in photosynthesis. It helps in capturing energy from light and converts it into chemical energy in the form of ATP molecules.

Thus, the correct answer is 'option (D).'

Answer 2

Well we know photosynthetic living things are usually NOT bacteria. They are usually plants and fungi. in this case I would choose C. but I don't know exactly everything about science so I wouldn't depend on this answer. But I do know what I said in the beginning, so it wouldn't be bacteria. Protista and archaea I don't know much about either. if you have a teach I would recommend asking him/her!
