A family takes its summer vacation at a beach resort. Six-year-old Timmy spends the entire morning in a swimming pool. When his mother finally gets him out and dries him off, she remarks that his fingers and toes are "wrinkled up just like a prune." Prunes start their lives as plums. They get their characteristic wrinkles by dehydration. Sitting for hours in water is anything except dehydration. How can you solve this mystery? Use the Internet to investigate the wrinkling of a prune and the wrinkling of the skin when it is immersed in water. Be sure to relate your discussion of this topic to the process of osmosis.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.
