If you are involved in a vehicle accident, you should not drink any alcohol up to ___ hours after the accident or you could be l
Luda [366]

Answer: 6

Explanation:

Alcohol is a psychoactive drug with a high number of side effects that can seriously affect our body. <u>The amount and circumstances of consumption play an important role in determining the duration of intoxication.</u> For example, consuming alcohol after a large meal is less likely to produce visible signs of intoxication than on an empty stomach.

Alcohol has a two-phase effect on the body, meaning that its effects change over time.  Initially, it produces feelings of relaxation and joy, but later consumption can lead to blurred vision and coordination problems.  Cell membranes are highly permeable to alcohol, so once alcohol is in the bloodstream, it can spread to almost all body tissues.  

Unconsciousness can follow excessive consumption, and extreme levels of consumption can lead to alcohol poisoning and death. Death can also be caused by asphyxiation, if vomit - a frequent result of excessive drinking - blocks the windpipe and the individual is too drunk to respond.  An appropriate first-aid response to an unconscious, drunk person is to place him or her in the recovery position.  

<u>When alcohol enters the bloodstream (30-90 minutes after ingestion), there is a decrease in the sugars present in the bloodstream, causing a feeling of weakness and physical exhaustion. </u> This is because alcohol accelerates the transformation of glycogen (a substance that stores sugar in the liver) into glucose, which is then eliminated more quickly.  

After the ingestion of alcohol, a series of effects or symptoms occur in the short term, depending on the dose ingested (although other individual factors are affected).

  • Euphoria and excitement phase
  • Intoxication: The nervous system is affected as the loss of the capacity to coordinate movements is caused, producing imbalance and sometimes falls. If abused, locomotor ataxia can occur, which is a paralysis characteristic of alcoholics.
  • Hypnotic or confused phase: Irritability, agitation, drowsiness, headache, ysarthria, ataxia, dysmetry, nausea and vomiting.
  • Anaesthetic phase or stupor and coma, inconsistent language.
  • Bulbar or death phase: Cardiovascular shock, inhibition of the respiratory center, cardio-respiratory arrest and death.

Alcohol is broken down mainly in the liver, which can metabolize about 1 drink per hour for men. Factors such as age, weight, gender, and the amount of food eaten can affect how quickly the body can process alcohol. The amount of time alcohol can be detected in blood is up to 6 hours. Then it is not recommended to drink alcohol until after 6 hours if you have been involved in an accident, since alcohol can be detected in the blood in that time range. <u>Because of the effects alcohol has on the body and how it can affect driving, if alcohol is detected you can be legally charged with driving under its influence.</u>

Questions
ASHA 777 [7]

Answer:

Explanation:

1. diffusion is a physical process when there is random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

2. Osmosis is the diffusion of water where molecules of water move passively (without energy) from high concentration to low concentration. eg: the way water rushes into a sponge.

3. Active transport moves particles from low to higher concentration. The difference between diffusion and active transport is diffusion does not require energy (eg: oxygen moving from the airways to the lungs - there is very little oxygen in the lungs but lots in the air).  whereas active transport does require energy (eg: when plants take up nutrients from the soil. The soil does not have a large concentration of nutrients, but the plant does)
