Answer:

C. 0,5 to 1 micrometer thick.

Explanation:

For an efficient gas exchange, the respiratory membrane must be 0,5 to 1 micrometer thick. That way gases are able to penetrate the membrane and get to the blood capilar as fast as possible. If the respiratory membrane was thicker, gases do not penetrate and go through the membrane as fast and efficient as in the previous case.

Make a recommendation letter to Mayor or your Brgy. Chairman about the dangers brought by drug abuse in the community. Sight pos
vlada-n [284]

Dear mayor.

I write this letter as a way to ask for measures for an evil that is plaguing our youth, drug abuse.

This abuse of drugs has been gradually increasing in our community and in other regions that are impacted by an insufficient economy and a flawed educational system, which has meant that young people find support only in the world of drugs.

The problem is that these substances are highly addictive, reaching the point where young people are unable to continue their lives, as they can only maintain their addiction. This opens the way for criminal and dangerous activities to be initiated, causing young people to lose their entire lives.

Therefore, I humbly ask that public policies be created to save our young people from this situation, in addition to regulatory policies for the use and sale of drugs. I believe that you will agree with the importance and urgency of this matter.

Thank you for your time.

Graciously.

M. Linn.

1. True or False: A low BAL will always cause a hangover. True False
liberstina [14]
1. I am completely sure that this statement is false. Because HIGH BAL will ALWAYS cause a hangover. BAL is a blood-alcohol level, which means a level of alcohol intoxication. High BAL can be produced drinks with congeners, like whiskey, tequila and cognac.

2.  According to its definition, complete statement should look like this: perception is what gives meaning to our senses. Perception is our ability to see or feel something. It helps us understand something or to become aware of something.

3. I am completely sure that judgment <span>is the first ability affected by alcohol. High blood-alcohol level badly affects your judgement, coordination, vision and memory. Drinking alcohol increases your risk for life threatening diseases. 

4. If my memory serves me well, the statement should be completed like this: </span><span>Alcohol, or any other drug which reduces the supply of oxygen in the bloodstream, can impair the sensitivity of the cones which, in turn r</span>educes the visual acuity or sharpness.
5. Hand-eye coordination, walking, and balance, also known as coordination, are adversely affected by alcohol. As I've mentioned it before in question 3 the coordination is badly affected by alcohol.

6. As far as I remember, short-term side effects of alcohol and other drugs include d<span>isrupted sleep. But it depends on an individual. All of the above can be the side effects of alcohol and other drugs. But if you need to choose only one option, than its the first one.

7. I am pretty sure that alcohol can increase fatigue because it's one of the effects of high blood-alcohol level. Driving while fatigued can cause slow reaction time and decreased headlights speed.

8. In my view, the correct answer is: </span>In the case of distance judgment, the brain receives two slightly different images from the two eyes. Brain receives nerve signals produced by encoding this images.

9. I am 100% sure that s<span>peed in addition to the effects of alcohol greatly reduces a driver's vision. Affected by the alcohol, driver's field of view is reduced and speed reduces it even more.

10. I think that this statement is definitely TRUE, because the kidneys are responsible for excreting excess water. </span>

During a nursing consultation you weigh an overweight Border collie. The dog weighs 35 kg and you tell the owner that he should
wolverine [178]

Answer:

A- 2/7 of the initial weight.

B- 28.58% of the initial weight.

Explanation:

A- To determine the weight fraction that the dog must lose to be healthy, we have to take into account the common divisor between 35 and 25. Both are divisible by 5, so we must calculate based on that number to obtain a comparable fraction between both weights.

So, the dog must go from weighing 35/35 to weighing 25/35, that is, from weighing 7/7 to weighing 5/7. Therefore, the dog should lose 2/7 of its weight to reach the ideal weight.

B- To determine the percentage of weight that the dog must lose to reach its ideal weight, it is determined through a cross multiplication:

35 kg = 100%

25 kg = X

(25 x 100) / 35 = X

2500/35 = X

71.42 = X

So, the 25 kg represents 71.42% of the initial 35 kg. Therefore, the 10 kg lost represent 28.58% of the initial weight (100 - 71.42).
