Explanation:

First Question: Which of these is a common illegal opioid?

• Acetaminophen (a) is a pain reliever/fever reducer, not an opioid.
• Amoxicillin (b) is an antibiotic, not an opioid.
• Heroin (c) is an illegal opioid drug.
• Ibuprofen (d) is a non - steroidal anti - inflammatory drug, not an opioid.

• Dopamine is associated with the brain's reward system. Drowsiness (a) is not a main effect of dopamine release.
• Anxiety (b) is not typically caused by dopamine release; in fact, imbalances in other neurotransmitters like serotonin are more linked to anxiety.
• Dopamine release in the brain is known to cause feelings of pleasure or euphoria (c) as it is part of the reward and motivation pathways.
• Hunger (d) is more related to hormones like ghrelin rather than dopamine release.

Answer:

c. Heroin
