Question

b. which comparison best describes the effects of nicotine on blood vessels?
a balloon being filled with water until its full
a fire hose with water turned on part way
a garden hose with water turned on full blast
a watering can with a sprinkler attachment

Explanation:

Nicotine causes blood vessels to constrict. A fire hose with water turned on part - way implies a restricted flow (constriction), similar to how nicotine affects blood vessels. A balloon filled with water (expansion), a garden hose on full blast (unrestricted flow), and a watering can with a sprinkler (diffused but not constricted flow) do not match the constricting effect of nicotine.

Answer:

a fire hose with water turned on part way
