Drugs interfere with 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.
Other 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 too amplifies or disrupts the normal communication between neurons.
Answer:
All of the above
Explanation:
Their all chemical change
Concentration: 2.5% w/v
Concentration w/v % = [mass of solute / volume of solution ] * 100
=> mass of solute = concentration w/v * volume of solution / 100
=> mass of solute = 2.5 * 750 ml / 100 = 18.75 grams
Also, using proportions you get to the same result:
2.5% w/v => 2.5 grams of NaOH / 100 ml of water
=> 2.5 grams of NaOH / 100 ml water = x grams of NaOH / 750 ml water
=> x grams of NaOH = 750 ml water * 2.5 grams of NaOH / 100 ml water
=> x = 18.75 grams of NaOH
Answer = 18.75 grams of NaOH
This. You welcome now can you plz give me thanks and brainly
Explanation:
Igneous rocks are found where plates diverge, as lava rises and fills the gap between the plates. Igneous rocks also form where plates converge. The subducting plate melts as it sinks into the crust of the Earth, and the melt rises into the overriding plate forming volcanoes.
