. What subunit of nucleic acids contains deoxyribose and what subunit contains ribose?

The nucleotides have a similar structure with three 'subunits': A phosphate group. A sugar group : deoxyribose in DNA and ribose in RNA. A nitrogenous base : adenine, cytosine, guanine, thymine or uracil. Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA). Deoxyribose is similar in structure to ribose, but it has an H instead of an OH at the 2′ position. Bases can be divided into two categories: purines and pyrimidines.

Explanation:

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

nucleus

would be most reasonable answer tbh
