Final answer:
None of the options (IQ, emotions, sleep) are unaffected by alcohol; all are impacted. Alcohol is a depressant that can hinder cognitive abilities, influence emotions, and disrupt sleep.
Step-by-step explanation:
The correct answer to which of the following is not affected by alcohol is d. none of the above. Alcohol can impact a person's IQ, affecting cognitive tasks and the ability to process information. It also affects emotions, leading to increased euphoria or sedation, depending on the level of intake. Furthermore, alcohol consumption can disrupt sleep patterns, leading to insomnia or poor-quality sleep.
Alcohol is a depressant, and acute alcohol administration can result in reduced alertness, impaired motor skills, and potentially complete loss of consciousness. These impacts can vary based on a person's blood alcohol concentration (BAC) and can include slurred speech, trouble walking, vomiting, respiratory depression, coma, or even death at extreme doses.
