Complete question:
When you eat a hamburger, some of the energy in the food is converted to ATP that your cells can use to do all kinds of work, some of the energy is stored for later use, and some of the energy is dissipated as heat. The amount of energy before and after eating the hamburger is the same. This illustrates the:
a. the cell theory.
b. the theory of evolution.
c. the central dogma.
d. the second law of thermodynamics.
e. the first law of thermodynamics.
Answer:
e. the first law of thermodynamics.
Step-by-step explanation:
The first law of thermodynamics is about the fact that the creation and destruction of energy are not possible. During any biological or other processes, one form of energy can be converted into another form. But the total amount of energy before and after the process remains the same. In the given example, the part of the energy of a hamburger is used to perform functions, the part is stored in tissues and rest is lost as heat. However, the total energy content remains the same. This represents the first law of thermodynamics.
