D

The carbohydrates, glucose, fructose, and galactose, have the same chemical formula (C6H12O6) but different structural formulas as represented in the figure

C

Which of the following states best describes how animals such as rabits obtain the carbon necessary for building biological molecules

B

Which of the following best describes how amino acids determines the tertiary structure of the protein

B

Researchers compared similar proteins from related organisms in different habitats. They found that the proteins from organisms living in harsh environments had a greater number of cysteine amino acids than did proteins from organisms not living in harsh environments. The structure of cysteine is shown. Bonds can form between the sulfur atom of different cysteine amino adies ( bonds).
