Answer:
Yes, your answer, nitrogen, is correct (the most appropriate option). However, oxygen is also a correct option.
Explanation:
Nitrogen exists on its own as a diatomic gas. However, it exists as organic nitrogen in nucleic acids such as DNA and RNA (as part of their nitrogenous bases) and in the amino (--
) group of amino acids.
Do note that a case can also be made for oxygen as a right option: like nitrogen, it exists as a diatomic gas and can be found in both nucleic acids and in the carboxylic group of amino acids.
Sulfur is not an appropriate option as nitrogenous bases (and nucleic acids) to the best of my knowledge do not contain sulphur although some amino acids like cysteine do.
Carbon is not also an appropriate option because elemental carbon does not exist in gaseous form even though it can be found in both nucleic acids and amino acids.

Red blood cells carry oxygen around the body. These specialized cells are outfitted with the substance hemoglobin, which is a protein, and is the actual oxygen carrying molecule on the cell. The cell has a unique shape that allows it to carry as much oxygen molecules as possible. Red blood cells also transport carbon dioxide away from cells and back to the lungs where the cells are then re-oxygenated.
The more plants and animals in a habitat, the greater the biomass, which is now habitats store energy. The greater the number of species the more competition there is for food between predators, which sustains their populations
Answer: you cannot use a punnet square to find the percentages of The offspring unless you have the genotypes of the parents. For example, is the white trait recessive? This means it will be homozygous lowercase (bb". Are the black feathers dominant, if they are, is it heterozygous or homozygous? (BB or Bb) Read the question because genetics is not rocket science.
