Answer 1

1. Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products.

Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
