Question

1. 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.
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.

Explanation:

Las células necesitan oxígeno (proveniente del aire) para la respiración celular, proceso esencial para la producción de energía (ATP). Si el equipo de respiración no funciona, las células no recibirán suficiente oxígeno, lo que afectará su función. Las opciones a, c y d no son correctas: a) las células no pueden funcionar sin moléculas (oxígeno) del aire; c) el sueño no compensa la falta de oxígeno; d) el cuerpo no puede funcionar normalmente sin oxígeno.

Answer:

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