They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.
Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.
Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.
To answer the problem we would be using this formula which isE = hc/L where E is the energy, h is Planck's constant, c is the speed of light and L is the wavelength
L = hc/E = 4.136×10−15 eV·s (2.998x10^8 m/s)/10^4 eV
= 1.240x10^-10 m
= 1.240x10^-1 nm
Answer:
Looks like A but I'm not sure.
Explanation:
dont take my word for it I might be wrong
You have a distance and a time so you can work out the bikes speed which would be distance/time so 40mph.
Answer:
E) be two times larger.
Explanation:
As we know that the relation between the resistance and the resistivity of the wire is given as:
where:
resistivity of the wire
length of wire
area of wire
resistance
Now, when the length of the wire is four times the initial length then for the resistance to remain constant:
where:
area of the new wire
we know that area of the cross section of wire is given as:
Hence the radius must be twice of the initial radius for the resistance to be constant when length is taken four times.
