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.

Explanation:

The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis.

The cycle of carbon is carbon is moved through the atmosphere (carbon dioxide) to organisms. It is then moved from one organism to the next in complex molecules. Next, it is brought back to the atmosphere as carbon dioxide again.

Simple explanation is carbon passed through the atmosphere and back to animals and plants.
