Which of the following domains include organisms that have a nucleus and
other membrane-bound organelles?
o
a. archaea only
o
b. eukarya only
o
c. archaea and eukarya
o
d. bacteria only
submit

The correct option is B. Eukarya only

Explanation:

Bacteria can be described as prokaryotic organisms that do not possess a nucleus. Their genetic material is generally present in the cytoplasm of the cell in a region called nucleoid. Some extra genetic material is found in them in the form of plasmids. Hence, option D is not correct.

The domain, Archae, contains prokaryotes and they lack a nucleus. Hence, option A and C are not correct.

Eukaryotes are multicellular organisms which contain a nucleus and other membrane-bound organelles. Hence, option B is correct.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
