B) One swims freely and the other often lives attached to a hard surface.
Answer:
The correct answer will be option-B.
Explanation:
Deoxyribose nucleic acid or DNA is the genetic material of the organism which is made up of nucleotide monomer. The structure of DNA is made up of two strands of nucleotides coiled in a helical structure thus providing a double-helical shape to the structure.
Each nucleotide of a strand is composed of a five-carbon sugar, phosphate group and nitrogenous bases. These molecules are arranged in anti-parallel fashion in DNA which provides the polarity to the DNA strand. One strand is read from the 5' to 3' direction whereas another form 3'to 5' direction.
Thus, Option-B is the correct answer.
Answer:
D. They used simple molecules from early times and put them in a simulation from that time and it made complex ones that we have now.

Explanation:
From the smallest single celled organism to the tallest tree all life depend on the properties and reactions of four marcro molecules which are carbohydrate, protein, lipids and nucleic acid.
This is because, these organic molecules are the building blocks of all living things and they are responsible for most of the structure and functions in the body.
