Answer:

d. nitrogen-containing base .

Explanation:

A nucleotide comprises a phosphate group, a pentose sugar and a nitrogenous base (nitrogen-containing base).

A nitrogenous base is a type of aromatic heterocyclic organic compound which essentially has nitrogen in it. The base can be a purine or pyrimidine. Purine nitrogenous bases are adenine (A) and guanine (G) while pyrimidine nitrogenous bases are cytosine (C), thiamine (T) and uracil (U).

Till the time a base is not attached to covalently linked phosphate group and a pentose sugar, it is known as nucleoside. But as soon as we attach any nitrogenous base to the nucleoside, a nucleotide is formed. So it means a nucleotide is nucleoside + nitrogenous base.

Examples are as under:

A nucleotide which has adenine as nitrogenous base is known as adenosine triphosphate (ATP) while a nucleotide which has guanine as nitrogenous base is known as Guanosine-5'-triphosphate (GTP).

Which path through the carbon cycle is possible?
arlik [135]

Answer:

Plant to animal to atmosphere.

Explanation:

  • The carbon cycle describes the recycling of carbon from and back to the atmosphere.
  • Plants utilize the carbondioxide present in the atmosphere to produce carbohydrates in the presence of light through the process of photosynthesis.
  • When plants are consumed by animals, the carbon becomes a part of the animal.
  • Animals break down glucose molecules into energy (ATP), releasing water and carbondioxide in a process called cellular respiration.
  • This carbondioxide, as it is useless for animal cells, is released back into the atmosphere through gaseous exchange in the lungs.
