Answer:

Drug abuse affect the way brain receives and process information

Explanation:

Drug abuse can be defined as the use of drug in amounts or by methods which are harmful to the individual or others.

Drugs affects the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons. Although these drugs mimic the brain's own chemicals, they don't activate neurons in the same way as a natural neurotransmitter, and they lead to abnormal messages being sent through the network.

Drugs such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals by interfering with transporters. This disrupts the normal communication between neurons.

What does planarian regeneration tell us about human regeneration?

AlekseyPX

A planarian can regrow any missing body part. Truth be told, in the event that you take a planarian and excise it into a few little pieces, every last one of those body sections can recover into an entirely different worm.

Hello may u pls help me with this I'm hella counfused

pantera1 [17]

Explanation:

(1) Is referring to Newton's first law, an external force (gravitational force) is applied to frogs motion, thus causing it to deviate from a straight line

(2) is referring to Newton's third law of motion, the action force is done by the ball hitting the ground and the direction is downwards, the reaction force is done by the ground transferring that same force to the ball, acting upwards

(3) I think it's also the first law, the person on a train is showing, the force to keep it at rest, the sudden halt of the train causes a reaction force to act on the person, does making the person move

(4) I think it's both Newton's second law and third law motion.

I hope these helps

I don't know what your key vocabulary is..., but this is your answer!!

When the amplitude of a sound wave increases, the intensity of the sound increases therefore the sound seems louder but does not change the pitch.

Therefore, if you increase the amplitude of the sound wave(s) of your cell phone ring, it will still sound the same yet louder.

For example, think of when you are increasing the volume on your phone... You are increasing the amplitude of your phone's speaker sound wave and whatever you were tuning in to would sound louder but would stay the same. It wouldn't go from a robot to a kitty sound now. Same concept happens when you decrease the volume on your phone yet this time you are decreasing the amplitude of a sound wave(s) and it gets softer.

I hope that helps you out!!

You are given two fat-like solid substances and upon analysis you determine that sample a has a higher melting point than sample

Sample A has a much stronger melting point and it will last longer than Sample B.

<span>A good way to control portion sizes when you eat out is to split an entre with a friend or eat only half and take the other half home. You have to eat fewer calories.Other ideas to eat more veggies, make oatmeal more filling with diced apples, and use a whole-wheat pita in place of bread so you can stuff it with more veggies.</span>
