10. Rico, a scuba diver, uses breathing gear to help him breathe air underwater. He always gets enough sleep and eats a good breakfast
before a dive. What could happen if his breathing gear broke during a dive
and he could not breathe as much air as usual? *

This question is incomplete as it lacks options. The options are:

A) It would be difficult to swim, because his cells cannot work without molecules from air.

B) It would not affect him because his cells are getting the different types of molecules they need from food to work properly.

C) It would not affect him as long as he slept enough.

D) It would not affect him because his body can function normally even if his cells do not have molecules from air.

The answer is A

Explanation:

Breathing gears called SCUBA are devices designed to help human divers breathe under water as oxygen is very scarce as one gets deeper into water. The scuba supplies the air needed to breathe under water in order to supply the oxygen molecules present in air into our cells for the synthesis of ATP (energy).

According to this question, Rico is reported to eat healthy foods and sleeps well, however, these cannot substitute for a constant supply of air. if Rico's breathing gear broke during a dive and he could not breathe as much air as usual, It would be difficult for him to swim, because his cells cannot work without oxygen molecules got from air i.e. oxygen from air is very needed to synthesize energy that cell uses to carry out its functions.
