(of an immature or stem cell) capable of giving rise to several different cell types.
Answer:
Nucleic acids are of two types DNA and RNA which are made up of monomeric units called nucleotides.
One monomer is one nucleotide which further consists of three parts:
1: Nitrogenous base
2: Sugar (a ribose sugar in RNA and a deoxyribose sugar in DNA)
3: Phosphate group
Explanation:
If we talk about single strand of nucleic acid DNA or RNA, there is a phosphodiester linkage that holds monomers together in a strand of nucleic acids. This phospho di ester linkage is formed when a condensation reaction occurs between a hydroxyl group of two sugars and a phosphate group.

Hope it help!
Im pretty sure the answer is c.
let me know if its correct
Answer:
Diatoms are mostly asexual members of the phytoplankton. Diatoms lack any organelles that might have the 9 + 2 pattern. They obtain their nutrition from functional chloroplasts, and each diatom is encased within two porous, glasslike valves. Which question would be most important for one interested in the day-to-day survival of individual diatoms?
C) How do diatoms with their glasslike valves keep from sinking into poorly lit waters?
Explanation:
Diatoms are some of the most important organisms living on earth because of its role on the oxygen production in the planet earth. The question "how do diatoms with their glasslike valves keep from sinking into poorly lit waters?" Because of the way their nutrition is obtained from functional chloroplasts and the way them encased within two porous, glasslike valves.
