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
Answer:
Okay
Explanation:
Human topoisomerase I plays an important role in removing positive DNA supercoils that accumulate ahead of replication forks. It also is the target for camptothecin-based anticancer drugs that act by increasing levels of topoisomerase I-mediated DNA scission. Evidence suggests that cleavage events most likely to generate permanent genomic damage are those that occur ahead of DNA tracking systems. Therefore, it is important to characterize the ability of topoisomerase I to cleave positively supercoiled DNA. Results confirm that the human enzyme maintains higher levels of cleavage with positively as opposed to negatively supercoiled substrates in the absence or presence of anticancer drugs. Enhanced drug efficacy on positively supercoiled DNA is due primarily to an increase in baseline levels of cleavage. Sites of topoisomerase I-mediated DNA cleavage do not appear to be affected by supercoil geometry. However, rates of ligation are slower with positively supercoiled substrates. Finally, intercalators enhance topoisomerase I-mediated cleavage of negatively supercoiled substrates but not positively supercoiled or linear DNA. We suggest that these compounds act by altering the perceived topological state of the double helix, making underwound DNA appear to be overwound to the enzyme, and propose that these compounds be referred to as ‘topological poisons of topoisomerase I’
Answer:Depending on the size of the tear, recuperation might take anywhere from 4 to 6 months or longer. Most activities can be resumed after six months, although the rotator cuff can take up to a year to heal.
Explanation:
Valves are like flaps or lids that are used to transport blood from the atria to the ventricles. They act as inlets and outlets of blood.
Explanation:
The atrioventricular valves are located Left and right that are in the middle of atria and ventricle on both sides of the heart while two semilunar valves separate the right and left ventricles from the pulmonary valve and aortic valve.
The Atrioventricular valves are the mitral valve and the tricuspid valve. Mitral valve is in the left side and tricuspid valve is in the right. they both are separated by the atrium and ventricle
The two semilunar valves are the pulmonary valve and aortic valve. the pulmonary valve is on the right side separated by the right ventricle and pulmonary artery. The aortic valve is on the left and is separated by the left ventricle and aorta.
