The chemical formula C6H12O6 is the same for glucose, fructose, and galactose. All of these are simple sugars that are made by organisms and used by organisms. Explain how these sugars can be made of the same atoms and in the same amount but be different sugars.

Explanation:

Sugars are polyhydroxy aldehydes or polyhydroxy ketones. This means that have several -OH groups in all of their carbons. According to the disposition of these groups in the molecule (whether they are facing up or down), they constitute one sugar or a different one.

These molecules are called isomers, specifically diastereomers because they have an opposite configuration in some chiral centers but the same configuration in others.

i think the miocene epoch spans the time from 23 million to 12 million years ago.

we would need to see the picture to answer it
