In the new six kingdom system of classification, the six kingdoms may be grouped into three domains. the four kingdoms that are grouped in the domain eukarya all contain organisms

composed of one or more Eukaryotic cells

Having one or more than one eukaryotic cells.

Explanation:

The domain Eukarya consist four kingdoms, which are Protista, Plantae, Fungi, and Animalia. All organisms that belong to domain Eukarya have eukaryotic cells, having membrane-bound cell organelles, such as nucleus, mitochondria, and chloroplasts.

These organisms may be unicellular (such as protists or some fungi) or multicellular (such as plants and animals), due to presence of one or more than one cells, respectively.  

Thus, the correct answer is 'having one or more than one eukaryotic cells.'

the answer will be a) proteins i believe

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
