Answer:
The correct option is <em><u>B. Eukarya only</u></em>
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.
The X chromosome from the father with hemophilia will have the hemophilia gene. The girl also gets an X chromosome from her mother. If she gets the normal X chromosome, the girl will be a carrier.

One class of phospholipids, the phosphoglycerides,are composed by three parts that define this type of lipid:
- backbone of glycerol
- two long-chain fatty acids
-phosphoric acid
- and one organic group
Sphingolipids are similar in shape but they have a different component. Instead of having glycerol, which is the case for phosphoglycerides, they use sphingosine.
To form a Sphingolipid are necessary:
-sphingosine as the backbone
-phosphate
-an organic group
