Carbohydrates, dna, and lipids can be found in living things as long molecular chains. which of the following statements best describes how dna differs from lipids and carbohydrates? a) only dna contains nucleotides b) only dna is found in the cytoplasm c) only dna has carbon atoms d) only dna is used for energy storage and structural support i would really appreciate if you answered

The correct answer will be option- A.

Explanation:

Four types of macromolecules are present in the living organisms which are lipids, carbohydrates, DNA and proteins.

All of these molecules play a different role in the organism and are formed of different monomers- the smallest structural unit of macro-molecules.

The DNA present in the organism differs from other molecules due to different monomer called "nucleotides" which join end to end to form long polymer chains.

Thus, option- A is the correct answer.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
