Question

which short-term physical effect of alcohol is mentioned in the video?

improved balance and coordination

dehydration leading to headaches and dizziness

permanent memory loss after one drink

increased reaction time

which organ is described as working overtime to metabolize alcohol and is at risk of cirrhosis?

heart

kidney

liver

pancreas

Explanation:

First Question (Short - term physical effect of alcohol)

• Option 1: Alcohol impairs balance and coordination, so "Improved balance and coordination" is incorrect.
• Option 2: Alcohol is a diuretic, causing dehydration which can lead to headaches and dizziness. This is a known short - term physical effect of alcohol.
• Option 3: Permanent memory loss after one drink is not a short - term effect of a single drink; memory issues from alcohol are more related to heavy or long - term use or blackouts (which are not permanent from one drink).
• Option 4: Alcohol slows reaction time (decreases reaction time in terms of speed of response), so "Increased reaction time" (in the sense of taking more time to react, which is a decrease in reaction speed) is incorrect as the wording is a bit confusing, but the main point is that the correct short - term effect among these is dehydration leading to headaches and dizziness.

• The liver is the primary organ responsible for metabolizing alcohol. Prolonged alcohol consumption can lead to liver cirrhosis as the liver has to work hard (overtime) to process the alcohol. The heart is for circulation, kidneys for filtration, and pancreas for digestion and blood sugar regulation, so they are not the main organs for alcohol metabolism related to cirrhosis.

Answer:

B. Dehydration leading to headaches and dizziness (assuming the options are labeled A - D with A being "Improved balance and coordination", B being "Dehydration leading to headaches and dizziness", C being "Permanent memory loss after one drink", D being "Increased reaction time")
