Why is DNA important for protein synthesis?

• DNA is used as a source of amino acids to produce a protein.

• RNA molecules build a DNA strand that synthesizes a protein.

• DNA interacts with the RNA to add amino acids during protein synthesis.

Which statement best describes the differences between the process of aerobic respiration and fermentation?

• Aerobic respiration requires oxygen and produces more ATP than fermentation.

• Fermentation requires water and produces the same amount of ATP as aerobic respiration.

• Fermentation does not require energy input and produces more ATP than aerobic respiration.

Which statement best explains why a jackrabbit's ability to control blood flow to its ears is important for surviving in a desert environment?

• Controlling blood flow enables the jackrabbit to absorb water vapor in the air.
