Constance and Jennifer both watch a lot of TV, but Constance tends to get up and walk around during the commercials. Which process accounts for the fact that Constance has maintained her weight, while Jennifer has put on 10 pounds?

This question is missing the options. I've found the complete question online. It is as follows:

Constance and Jennifer both watch a lot of TV, but Constance tends to get up and walk around during the commercials. Which process accounts for that fact that Constance has maintained her weight, while Jennifer has put on 10 pounds?

a. Archimedes Principle

b. non-exercise activity thermogenesis (NEAT)

c. Dual-energy X-ray absorptiometry

d. hydro-static pressure

e. skinfold variance

The correct answer is letter b. non-exercise activity thermogenesis (NEAT) .

Explanation:

Even though both women are not truly exercising, Constance is still burning calories due to non-exercise activity thermogenesis (NEAT) . Everything we do demands energy and, of course, exercising usually spends the most energy, burning more calories. But even other types of physical exertion burn calories, such as standing up, walking around, running to catch a bus, etc. Jennifer's body is also expending energy but, since it is at rest, it is doing so in a lower rate than Constance's.

your answer is "graduates" hope this
