Which part of the nucleotides' structure is responsible for the incredible variation that exists amongst all types of organisms?
The part of the nucleotides' structure that is responsible for the incredible variation among all types of organisms is the nitrogenous base. The different types of nitrogenous bases (adenine, thymine, cytosine, and guanine) can combine in various ways to create different sequences of DNA or RNA, leading to the diversity and uniqueness of genetic information in different organisms.
Which of the following is a primary function of carbohydrates?
A primary function of carbohydrates is providing energy for the body.
