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?
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.
с
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.
