"In 1944, Avery, Macleod, and McCarty provided direct evidence that DNA was the hereditary molecule. They treated heat-killed extracts from lethal SIII bacteria with various enzymes and found that transformation was prevented only upon treatment with ."

Deoxyribonuclease (DNase)

Explanation:

Deoxyribonuclease  is an enzyme that degrades DNA by separating the phosphodiester bond that serves as the backbone of all DNA.

When the heat-killed extracts from lethal SIII bacteria was treated with DNase, transformation was prevented because the enzyme degraded the molecule that is responsible for transformation, that is the DNA.

and after water is usually warmed by the sun the water temperature raises and then evaporates .

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
