According to the National Institute of Health, atrial fibrillation occurs if rapid, disorganized electrical signals causing the

heart's two upper chambers, called the atria, to fibrillate. The term "fibrillate" means to contract very fast and irregularly. In atrial fibrilation, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should.
Based on the passage above, how will atrial fibrillation affect blood pressure?

It will lower blood pressure because less blood is pumped per beat.
It will increase blood pressure because the heart is contracting faster.
It will increase blood pressure because the atria fill fully with blood.
It will lower blood pressure because blood volume drops in the atria.

20% of wood is damaged and thrown away and only 20 kilograms is left vv is its original weight​
sesenic [268]
The original weight is 4.

Explanation:

20%= 1/5 if u don’t know the percentage then u can simply by doing..

20/100 then u divide it. U can do this by any other numbers such as 2, 4,5,10 and 20. U can do which ever way u like but i would recommend doing it either by 10 or 20.

So if we divide it by 20 we do...

20/100 divided by 20= 1/5

Or

20/100 divided by 10= 2/10

2/10 divided by 2 = 1/5

You can see the bigger the number that fits in is faster, although u can do it any way u feel like doing.

So we have got 1/5 from 20%. Now we do...

1/5 divided by 20. So when we do this, we use the bottom number to divide it and the top number to times it.

So..

1/5 u could use as 20 divided by 5..
Then 1 times the number that u get from ur before sum.

The answer is 4.

Because 1/5= 20 divided by 5 = 4
Since we have a 1 left we do..

4 times 1 which is... 4.

( u don’t need to show these parts in doing ur working, but i am doing these so they can help u understand)

So the answer is 4 and is the original weight.

I hope this is clear and helps u! :D

One year, heavy rain makes Lake Raymond very deep. The next year, however, rain is very light, and not much water is left in Lak
laila [671]

Answer:

There will be less animal life in lake Raymond in the next year.

Explanation:

In the year with heavy rain, this has caused the depth of Raymond lake to be increased. This will bring an increase in the growth and survival of more water plants and animal species.

In the second year where there is a decrease in the water level, the animals and water plants will face problems. The worst hit are those plants and animals species that lives at a much deeper path of the lake with the least sunlight or any external factors that are now going to be more exposed due to low water level..
