The factors affecting the blood alcohol concentration are:
gender
blood type
age
Explanation:
Blood alcohol concentration (BAC) refers to the amount of alcohol in the bloodstream per unit of blood. As individuals age, the effects of alcohol become increasingly evident. Ethanol dissolves well in water. Females typically have a lower water percentage in their bodies compared to males, leading to a higher BAC when consuming alcohol at the same rate as their male counterparts. Additionally, a person’s weight is directly proportional to their water content, which acts to dilute the alcohol consumed.
