Explanation:

• For the first law of thermodynamics: The first law of thermodynamics is the law of conservation of energy. It states that energy can be transformed (changed from one form to another), but cannot be created or destroyed.
• For ATP description: ATP (adenosine triphosphate) is often described as a rechargeable battery. When a cell needs energy, it breaks the high - energy phosphate bonds in ATP. When energy is available, ATP can be re - synthesized.
• For the second law of thermodynamics: The second law of thermodynamics states that the entropy (a measure of disorder) of the universe is always increasing.
• For the reaction that absorbs energy: An endergonic reaction is a reaction that absorbs energy. In contrast, an exergonic reaction releases energy, and a spontaneous reaction is one that occurs without the input of external energy (but not all spontaneous reactions are exergonic in the strictest sense, but endergonic reactions require energy input). A chemical reaction is a very general term.

Answer:

1. b. Energy can be transformed but not created or destroyed
2. c. As a rechargeable battery
3. b. Entropy in the universe is always increasing
4. b. Endergonic reaction
