Which of the following best compares the structure of carbohydrates and nucleic acids?
a. carbohydrates consist of monomers of carbon, hydrogen, and oxygen, while nucleic acids consist of monomers of a sugar, a phosphate group, and a nitrogenous base.
b. carbohydrates have four rings containing carbon, hydrogen, and oxygen, while nucleic acids have subunits containing an amino acid and a phosphate group.
c. carbohydrates contain carbon, hydrogen, and oxygen and have a hydrophobic end and a hydrophilic end, while nucleic acids contain a carbon backbone, a side change, and an amino group.

The most appropriate answer is A.   Both carbohydrate and nucleic acids are polymers with Carbohydrate being a long chain of repeated monomers of carbon, oxygen and hydrogen bonded while the nucleic acid is made up of repeating structures of sugar, phosphate and nitrogenous base groups. 

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
