Answer:
Carbohydrates are organic molecules ONLY composed of carbon, hydrogen, and oxygen molecules. So, their structure would be just covalent bonds between the three elements, and most likely non-polar. They give out a lot of energy, and carbohydrates are also known as sugars. Most foods have them.

The reason for the change in the hands of the chimpanzee include:
- Crossbreeding between gorillas and chimpanzees( Represents a reason for the change)
- Mutations in chimpanzee DNA ( Represents a reason for the change)
- Differences in the ways chimpanzees use their hands ( Doesn't represents a reason for the change)
- Sexual reproduction ( Doesn't represents a reason for the change)
- Differences in enhancer sequences( Represents a reason for the change).
<h3>What is mutation?</h3>
Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:
- When there is spontaneous break down of deoxyribonucleic acid (DNA).
- Change in a single nucleotide of the DNA.
- when there is additions or deletions of nucleotide in a DNA strand.
A change can be noticed in an animal such as Chimpanzee when the following occurs:
Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.
Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.

those are nucleotides 
since all three of them contain deoxyribose (because there's only one hydroxil group) they are DNA nucleotides
the first nucleotide has cytosine as it's nitrogenous base 
the second nucleotide has adenine as it's nitrogenous base 
the third nucleotide has thymine as it's nitrogenous base
