Use the drop-down menus to label the parts of a nucleotide.
Label A
Label B
Label C
Label D
Label E
Label F.

A and F are phosphate groups.

B and E are sugars.

C and D are nitrogenous bases.

Explanation:

Nucleotides are the molecules responsible for composing DNA and RNA. They are formed by three units: a phosphate group, a sugar molecule and a nitrogenous base.

The sugar molecule is a pentose, which means that it is a molecule formed by 5 carbons. These collections are represented by geometrical figures such as the letters "B" and "E" shown in the figure above, where each tip represents a carbon.

The nitrogenous bases are molecules that are named adenine (A) and guanine (G) and the pyrimidine bases cytosine (C), uracil (U) and thymine (T).

The phosphate group, in turn, is a molecule derived from phosphoric acid and is the only one that does not vary in each nucleotide.

not too sure but maybe in the hot springs.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
