Macromolecules contain varying amounts of energy, as shown in the table below. Protein 4
Fat 9
Carbohydrate 4

Animals that hibernate in the winter require more fats in their diets. Fat will break down over a longer period of time than carbohydrates and allow the animal to survive the winter.

a) Describe some other kinds of activities that would benefit the most from each molecule in the table.

the correct answer is(the type of energy described here is potential energy.)

explanation: now if the person holding the bow and arrow has now let go. the arrow shoots forward toward its target. the   type of energy then becomes

it would lead to upper respiratory infections and pneumonia.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
