Answer: Option B) phosphate; hydroxyl; 3'
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'
carbon atom
Explanation:
For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).
While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.
Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group

Answer:
Walking
Explanation:
A muscle cell usually contracts or expands simultaneously when one is working or doing some activities like running, exercises, house chores e.t.c
Muscles are flexible fibers that are very essential appendages for locomotion in human beings.
For muscle cells to contract, they are pulled together thereby causing tension in the muscle. When they are relaxed, they move away from one another.
Not entire sure because I haven't taken human anatomy but I'd guess it would have to be the digestive enzymes breaking it down
