Final answer:
A woman and a man with the same body weight drinking the same amount of alcohol will have different blood alcohol levels because women metabolize alcohol more slowly than men. This results in generally higher BAC in women. The rate of alcohol metabolism also varies between individuals.
Step-by-step explanation:
A woman and a man who have identical body weights and who both drink the same amount of alcohol will typically have different blood alcohol levels. This is because several factors, including biological sex, affect how alcohol is metabolized in the body. Women metabolize alcohol more slowly than men, often leading to higher BAC (blood alcohol concentration) in women compared to men with the same body weight after consuming the same amount of alcohol. As BAC increases, it has a range of effects on the body, and it's important to remember that reactions to alcohol can vary widely between individuals. Breathalyzer tests are used to measure ethanol concentration, which reflects BAC, and the legal limit for driving in most US states is 0.08%. Finally, alcohol is metabolized in the human body at a rate of approximately 3.3 mmol/L (15 mg/dL) per hour, but this rate can vary between individuals.
