Answer:

Drugs affect how neurons send and receive signals

Explanation:

Different drugs have different abilities to induce responses in the brain, but all drugs basically alter the mode that neurons receive, process and send signals via neurotransmitters. Marijuana contains THC (tetrahydrocannabinol) and other psychoactive substances that bind to cannabinoid receptors in the brain, causing different effects (e.g., increased heart rate, reversible depression, altered ability to perform complicated tasks, etc). Cocaine is a stimulant drug (i.e., a drug that accelerates the messages between the brain and the rest of the body), which has many side effects. This drug (cocaine) binds to dopamine receptors in order to stimulate rapid responses by increasing the level of dopamine pumped into the brain. Alcohol is a depressive drug that binds to opioid receptors in the brain called 'Mu receptors', which are required for controlling diverse emotions (e.g. pain, pleasure, and reward, etc). Finally, mescaline is a psychedelic drug that binds and stimulates dopamine and serotonin receptors, thereby causing hallucinogenic effects.

What are five body functions that monitor homeostasis?
KIM [24]

It regulates temperature, glucose, toxins, blood pressure, and pH.

<span>Temperature
The body must maintain a relatively constant temperature. If it gets too hot, the body employs vasodilation to cool down. This dilates the blood vessels, allowing more heat to escape from them through the skin.Glucose
The body must regulate glucose levels to stay healthy. When glucose levels become too high, the body releases a hormone called insulin. When they become too low, the body converts the glycogen in the blood to glucose.Toxins
Toxins in the blood can disrupt the body's homeostasis. Thus, it signals the urinary system to ensure that the toxins are excreted.Blood Pressure
The body must maintain healthy levels of blood pressure. To do so, the brain sends signals to the heart to speed up or slow down according to the blood pressure.pH
The lungs control the pH amount in the body. If pH levels become unbalanced, the lungs push more or less carbon dioxide out of the diaphragm. This can raise or lower pH levels in the body.</span>
