It depends if you're talking about Physical Science or Physics/Biology -- so, I'll give both definitions (: Physical Science: the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass. Physics/Biology: a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material. Hope that helped! (:

Bacterial cells usually have cell walls, as do animal cells. a. True b. False

olga2289 [7]

Answer:

False.

Explanation:

Bacteria are the prokaryotic organism that lacks the well developed nucleus and the membrane bound cell organelle. The animal cells are the eukaryotic organisms.

Bacteria cells have cell walls that are made of the peptidoglycan layer. The cell wall of bacteria are important as it protect themselves from the extreme environment. The animal cells do not contain cell wall and they have plasma membrane only in their structure.

Thus, the correct answer is option (b).
