Which statement describes only one way that rna differs from dna? a. one is a protein, and the other is a nucleic acid. b. they contain different five-carbon sugars and a different nitrogeneous base. c. they are both carbohydrates, but one is a polysaccharide. d. one provides energy, and the other carries genetic information.

DNA stands for Deoxyribonucleic acid which means it is a nucleic acid. RNA stands for Ribonucleicacid. RNA produces proteins

DNA replicates and stores genetic information.

RNA converts the genetic information contained within DNA to a format used to build proteins.

I would have to say the answer is A based off the information above.

Please correct me if I'm wrong.

b

oxidation

explanation:

answer

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
