Scientific knowledge is always changing. At one time, the kingdom was the highest level of
classification. Today, the highest level of classification is the domain. Two of
the domains, Bacteria and Archaea both contain microscopic prokaryotic
organisms. What would be the best reason for scientists to separate the
prokaryotes?
A)There were too many species of prokaryotes to only have 1 domain for them.
B)It was determined that neither have chloroplasts.
C)Both organisms do not contain organelles.
D)Research showed differences in living environments.

D

Explanation:

Organisms can be separated into different classifications due to many differences phenotypically or genetically. As we have progressed, research has shown differences allowing us to see bacteria and archaea as different organisms.

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
