a strand of dna contains 10% adenine. what percentage of cytosine must be present in this strand of dna then?
a) 80%
b) 40%
c) 10%
d) 20%
Answer:
[tex]\boxed {\boxed {\sf B. \ 40 \% \ cytosine}}[/tex]
Explanation:
First, recall the base pairs in DNA:
Adenine and Thymine Cytosine and GuanineWe know this strand of DNA has 10% adenine. Since A and T pair, there must also be 10% guanine.
So, A and T make up 20% of the DNA strand.
That leaves 80% for cytosine and guanine. They are pairs, so they share this percentage equally.
80/2 =40There must be 40% cytosine and 40% guanine.
The strand of DNA has 40% cytosine

why blood flow in a leg vein is slow when there is lack of movement?
Answer:
Lack of movement allows blood to circulate in a vein very slowly by sitting still for long periods of time. Slow-flowing blood is more likely to clot than normal-flowing blood. This issue is referred to as deep vein thrombosis (DVT). In DVT, as seen in the diagram, the clot normally takes place in a leg vein.
Explanation:
Lack of movement by still for long periods of time makes blood flow very slowly in a vein it is because the blood that flows slowly is more likely to clot than blood that flows normally.
What are the veins called in the leg?Large leg veins are saphenous veins. The leg veins that become weak in the most people age are the superficial veins and perforator veins.
The superficial and undesirable visible branches are known as varicose, reticular, and spider veins.
When sitting still, the flow of blood flow becomes slow, it is caused because the blood that flows slowly is more likely to clot than blood that flows normally.
This condition is called deep vein thrombosis.
Thus, due to this condition, blood flow in a leg vein is slow when there is lack of movement.
