Question

which of these factors may affect a persons blood alcohol concentration? gender race blood type age

Explanation:

Gender can affect blood - alcohol concentration because men and women generally have different body compositions and levels of enzymes that metabolize alcohol. For example, women tend to have more body fat and less water than men of the same weight, which can lead to higher blood - alcohol concentrations for the same amount of alcohol consumed. Race, blood type, and age have less direct and significant impacts on blood - alcohol concentration compared to gender.
