Animals, plants, fungi, and protists are made up of eukaryotic cells, which are cells that a. are organized into complex structures enclosed in membranes. b. can produce their own energy through photosynthesis. c. do not contain a nucleus or any genetic information. d. always contain several chloroplasts that capture energy.

A is the answer.

Eukaryotes are organisms whose cells have a nucleus and other organelles enclosed by a plasma membrane.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
