Nucleotides, which are the building blocks of nucleic acids, consist of a phosphate group, a nitrogenous base, and a

Ribose sugar

Explanation:

Nucleic acids are polynucleotides, which are composed of a long chain molecules of nucleotides. Each nucleotide is made up of:

1. Nitrogen-containing base, which can be Adenine, Guanine, Cytosine and Thymine or Uracil (depending on whether it is DNA or RNA)

2. A phosphate group, which is a phosphorus atom attached by a covalent bond to four oxygen atoms (PO4). The arrangement makes it able to store high energy.

3. A five-carbon sugar known as ribose, the ribose sugar can either be without oxygen (deoxyribose) as in DNA or with oxygen as in RNA.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
