Answer:
Codeine
Explanation:
Codeine is an opiate and is used to treat mild and moderate pain. It is also the main ingredient in prescription based cough suppressant. It belongs to a class of drugs known as opioid analgesics.
Codeine is a naturally occurring phenanthrene alkaloid with opioid agonist and can be extracted directly from the plant although most codeine is synthesized from the opium poppy.
They are thus known as the "supporting cells" of the nervous system. The four main functions of glial cells are: to surround neurons and hold them in place, to supply nutrients and oxygen to neurons, to insulate one neuron from another, and to destroy and remove the carcasses of dead neurons (clean up).
Answer:
becomes accumulated in the blood
Explanation:
The processing of alcohol is constant in every individual. The rate at which alcohol stays in someone's body is determined by how much of it is consumed.
Alcohol enters the digestive system once ingested and travels to the stomach and small intestines. The amount of alcohol absorbed in the small intestine enters directly to the bloodstream. Once in the blood, alcohol is circulated with it. The liver is responsible for the metabolic elimination of most (about 95%) of ingested alcohol from the body. If an individual consumes more than this, the system becomes saturated, and the additional alcohol will accumulate in the blood and other tissues until it can be metabolized. If this happens frequently or too fast, damage to the brain and tissues of the body can occur.
Blood Alcohol Concentration (BAC) depends on the amount of alcohol consumed and the rate at which the individual's body metabolizes alcohol. Because the metabolism of alcohol by the body is constant, taking in alcohol at a rate higher than the rate of metabolizing it results in a cumulative effect and increase in the blood alcohol concentration.
It is important to note that, the more one drinks the longer alcohol stays in the system.
Answer:
Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.
