Answer:
A DNA molecule is in the shape of a double helix twist, so it will look like a ladder.
Explanation:
The answer is population!
The molecular weight of glucose is approximately 180 daltons so each mol of glucose will be equal to 180g glucose. The concentration of glucose in the blood would be: 100mg/dl * 1 mol/180g= 5.55 mol/dl * 10^-4
Molar is expressed as mol per liter, so you need to change the volume into liters. The calculation would be: 5.55 mol/dl * 10^-4 * 10dl/liter= 5.55 * 10^-3 M= 5.55 millimoles
About 10% because I know about 90-95% of DNA is junk DNA(doesnt perform serious function)
A similar gas to Nitrogen would be Phosphorus as it is in the same group as Nitrogen. The least similar would be Neon as it os a very stable noble gas in a different group.
