Dna and rna share a number of similarities but they also differ in certain aspects of their structure which nitrogenous base is found in dna but is not found in dna

Uracil

Uracil is the nitrogenous base that is found in RNA but not present in DNA.

Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine. RNA contains uracil (U) instead of thymine (T).

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
