Which of the following is correct and literally explains the law of Energy Conservation?
a. Glycogen is the short-term energy conservation in the body of animals.
b. Cellular respiration conserves the energy of the sun in all living things.
c. Proteins are the body's second priority for energy conservation.
d. During energy transformation, part of the total energy is always wasted as heat.
e. A brand new car can run 35 miles per gallon of gas while an old car of the same make, can run only 15 miles per gallon
f. Two of the above
g. None of the above
Law of energy conservation:
The law of conservation of energy is also known as the first law of thermodynamics. It states that during energy transformations, the total energy in any given system always remains the same.
Answer and Explanation:
The correct response is f. Two of the above. This is because option a. (Glycogen is the short-term energy conservation in the body of animals) and option d. (During energy transformation, part of the energy is always wasted as heat) are both true. Glycogen is used as a storage carbohydrate in animal cells, whilst heat energy is given off in most energy transformations.
