Answer:
Sugars and phosphates
Explanation:
DNA is deoxyribonucleic acid.
The backbone is based on a repeated pattern of a sugar group (deoxyribose) and a phosphate group.
The image below shows one straightened-out strand of DNA with a backbone of alternating sugars and phosphates.
A is wrong. There is no ribose in DNA.
B is wrong. The nucleic acids A, C, G, and T join one strand of DNA to the other.
C is wrong. There is no RNA in DNA.
Symbolic interactionists see society as being continually reconstructed by individuals through their use of shared symbols.

The paramecium would not be able to get rid of excess water so the cell would burst.
FUNCTION OF THE CONTRACTILE VACUOLE:
- The contractile vacuole is an organelle present in protist organisms like paramecium, amoeba etc.
- The contractile vacuole functions to regulate water balance in the cells of organisms that they are found. Contractile vacuole performs this function by storing excess water and expelling the out of the cell.
- Hence, if a disease affected a paramecium's contractile vacuoles, stopping the normal functioning of the vacuoles, the paramecium would not be able to get rid of excess water so the cell would burst.
