It is broken down to provide usable chemical energy.

B
It stores and transmits genetic information.

C
It transports oxygen in the blood.

D
It helps plants retain water.

Answer 1

B

Step-by-step explanation:

This macromolecule is DNA. Its stored genetic information in form of genes that translate to functional or structural proteins that make up an organism. The DNA double helix is unzipped by helicases enzymes into single strands. RNA polymerase transcribes the single strands into mRNA. The mRNA is then translated into proteins by ribosomes. This is called the central dogma (DNA  RNA  Proteins).

During cell division, the DNA is replicated into two copies and each copy goes to each of the two daughter cells preserving, more or less, the same genetic code to the new cells.
