Question

you discover a new life form, and study it under an electron microscope. you find that it has no organelles, a peptidoglycan cell wall, and fatty acids in its plasma membrane. you conclude that the new life form is in domain
bacteria.
archaea.
eukarya.
protista.
animalia.

Explanation:

Eukarya (including Protista and Animalia) have membrane-bound organelles, so they are eliminated. Archaea lack peptidoglycan in their cell walls and have unique membrane lipids instead of fatty acids. Bacteria are prokaryotes (no organelles) with peptidoglycan cell walls and fatty acids in their plasma membranes, matching the described life form.

Answer:

A. Bacteria.
