What could you determine about a specimen if you observed a slide image showing the specimen with a cell wall, but no nucleus or mitochondria?

The correct answer is a prokaryotic cell such as bacteria.

Explanation:

A unicellular organism that lacks a true nucleus, mitochondria, or any other membrane-bound organelle such as mitochondria, chloroplast. Prokaryotic cells have a cell wall. Bacteria is a microscopic prokaryotic cell contain a rigid cell wall made up of peptidoglycan and no true nucleus or double membrane organelle.

Prokaryotes have a simple cell structure without any compartmentalization. A Prokaryote divide by binary fission.

Thus, the correct answer is a prokaryotic cell.

The specimen most likely is can be determined to be a prokaryotic cell.

An important and distinguishing feature of a prokaryotic cell is that it has no nucleus nor mitochondrion.

A prokaryotic cell is a unicellular cell having a cell wall that houses other organelles with no nucleus.

Organisms that fall within the Bacteria and Archaea domains are prokaryotic cells. They are said to be very abundant on earth.

An image of a prokaryotic cell is shown in the attachment.

The observed specimen that has no nucleus nor mitochondria,  but has a cell wall can be determined to be a prokaryotic cell.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
