Question

What is most likely to occur when the brain is repeatedly flooded with artificial opiates?

1) The brain stops making melatonin.
2) The level of serotonin is permanently decreased.
3) The brain stops producing endorphins.
4) The immune system is suppressed.
5) The brain shrinks.

Answer 1

Repeatedly flooding the brain with artificial opiates can cause the brain to stop producing endorphins, which are natural painkillers.

Step-by-step explanation:

When the brain is repeatedly flooded with artificial opiates, it is most likely that the brain stops producing endorphins. Endorphins are natural painkillers produced by the brain, and when the brain receives artificial opiates, it no longer needs to produce endorphins. This can lead to a decrease in the brain's own pain-relieving capabilities.
