A. Is performing a safety stop

B. Starts ascending

C. Is performing a decompression stop

D. Starts descending - ANSWER- B. Starts ascending

On desaturation, the inert gas diffuses from the tissues into the

bloodstream, from the blood into the alveolar air, and then:

A. Back into the blood stream

B. Out of the body with each exhalation

Multi-level dives, in general, are those where:

A. All of the answers are correct

B. Divers spend time at progressively deeper depths during the dive,

which allows extended bottom time

C. Divers spend time at progressively shallower depths during the dive,

which allows extended bottom time

D. Divers spend time at progressively shallower depths during the dive,

which allows less bottom time - ANSWER- C. Divers spend time at

progressively shallower depths during the dive, which allows extended

bottom time
