Answer:
a. endothermic
Explanation:
- Endothermic reaction: is a chemical reaction that absorbs heat or energy through the reaction.
- While, exothermic reaction: is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction.
<em>So, Any reaction that absorbs 150 kcal of energy can be classified as </em><em>a. endothermic.</em>
The statement 'photosynthesis and cellular respiration are opposite reactions' best describes the relationship between photosynthesis and cellular respiration.
<h3>What is cellular respiration?</h3>
Cellular respiration is a chemical process where foods and oxygen are used to generate ATP in aerobic conditions.
Conversely, photosynthesis is a chemical process where light and carbon dioxide are used to generate chemical energy.
In conclusion, the statement 'photosynthesis and cellular respiration are opposite reactions' best describes the relationship between photosynthesis and cellular respiration.

Answer:
Endothermic means: accompanied by or requiring the absorption of heat. So therefor cold packs would not be endothermic because they don't release cold. Instead they absorb heat
Explanation:
204 can be factored into 2 and 102, then 102 can be factored into 1 and 51, and then 51 can be factored into 3 and 17. So then you would get 2*3*17*1.
