Question

multiple choice question
water becomes supersaturated if it ______.
o contains more than 100% oxygen
o contains no respiring creatures
o is agitated at the surface
o gets very warm

Explanation:

Supersaturation in water often occurs when it contains more dissolved gas (such as oxygen) than its normal saturation level under given conditions. Having more than 100% oxygen implies it has exceeded the normal saturation amount of oxygen, leading to supersaturation. The other options - lack of respiring creatures, surface - agitation, or getting very warm - do not directly relate to the concept of supersaturation in terms of dissolved substances.

Answer:

contains more than 100% oxygen
