Question

who invented scuba gear?
select one:
a. jacques cousteau
b. steve jobs
c. steve weisberg

why do dead fish float?
select one:
a. their swim bladder bursts
b. decomposing bacteria produce gases in the fish that make them float
c. fish flesh is less dense than water

Explanation:

For the first question: Jacques Cousteau co-developed the first commercially successful open-circuit SCUBA system (Aqua-Lung), while the other options are unrelated to underwater gear invention.
For the second question: When a fish dies, decomposing bacteria break down its tissues, producing gases like methane and ammonia that accumulate in the body, reducing its overall density enough to make it float; swim bladder bursting is not the primary cause, and fish flesh is denser than water when alive.

Answer:

1. a. Jacques Cousteau
2. b. Decomposing bacteria produce gases in the fish that make them float
