Explain the processes involved when drugs such as cocaine, marijuana, mescaline or alcohol enter the brain.

Answers

Answer 1

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.

Give a summary of the guidelines for using sunscreen to prevent overexposure.

Answers

Answer: Sunscreen is a product that helps to protect your skin from the harmful effects of the sun's ultraviolet (UV) rays. Here are some guidelines for using sunscreen to prevent overexposure:

1. Choose a sunscreen with a sun protection factor (SPF) of at least 30.

2. Apply sunscreen to all exposed skin, including your face, neck, ears, and the backs of your hands.

3. Use enough sunscreen to cover your skin completely, and rub it in well.

4. Reapply sunscreen every 2 hours, or immediately after swimming or sweating.

5. Wear protective clothing, such as a hat, shirt, and sunglasses, to further protect your skin from the sun.

It's important to follow these guidelines to help protect your skin from the damaging effects of UV radiation and reduce your risk of skin cancer.

To prevent overexposure to the sun, here are some guidelines for using sunscreen:

1. Choose the right sunscreen: Look for a broad-spectrum sunscreen that protects against both UVA and UVB rays. It should have a Sun Protection Factor (SPF) of 30 or higher. Higher SPF values provide more protection, but no sunscreen can block 100% of the sun's rays.

2. Apply sunscreen generously: Apply a generous amount of sunscreen to all exposed areas of your body. Don't forget commonly missed areas like the ears, back of the neck, and tops of the feet. Apply it at least 15 minutes before going outside to give it time to absorb into the skin.

3. Reapply frequently: Reapply sunscreen every two hours, or more often if you're sweating or swimming. Even waterproof sunscreen can wear off, so it's important to reapply regularly for continued protection.

4. Use additional protection: Sunscreen is just one part of sun protection. Seek shade during the sun's peak hours, usually between 10 a.m. and 4 p.m. Wear protective clothing, such as long-sleeved shirts, pants, and a wide-brimmed hat. Sunglasses that block UV rays can also help protect your eyes.

5. Be mindful of other products: Some skincare products, like moisturizers or makeup, may contain a small amount of sunscreen. While they can provide some protection, they shouldn't be relied upon as the sole source of sun protection. It's best to use a dedicated sunscreen for optimal coverage.

Remember, using sunscreen is essential for preventing overexposure to the sun and reducing the risk of skin damage and sunburn. Following these guidelines will help ensure you're using sunscreen effectively and staying protected. Stay safe under the sun!

A gene mutation occurs that causes an organism to produce more of an enzyme that helps repair damaged cells. Predict how this will impact the organism.

Answers

The correct answer is B. The organism will take less time to repair cells.

Explanation

A genetic mutation is a concept that refers to changes that alter the nucleotide sequence of DNA. These mutations can lead to effects in the body that can be malignant or benign. An example of the malignant effects can be produced by contact with radiation that causes diseases such as cancer in the body. On the other hand, some mutations can cause benign effects such as the increase of enzymes that help to carry out processes in the body in less time than normal, for example, the enzymes involved in repairment of cells. In this case, the enzymes can lead to a shorter healing time. So, the correct answer is B. The organism will take less time to repair cells.
