faltersainse [42]

Answer:

Photoperiodism

Explanation:

The process explained in the question is called "Photoperiodism" which refers to the plants' reaction to the length of the dark and light period in a day.

When the dark period is interrupted with a certain period of artificial lighting, the plant thinks that the day had a longer period where it's "light" than it is "dark" so it gets tricked into flowering. Same concept can be applied in reverse for the plants who flower during longer periods of dark.

I hope this answer helps.

A nucleotide consists of a phosphate group, a pentose sugar, and a __________________, all linked together by covalent bonds. po
solong [7]

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).
