How does paraffin move up the wick
aleksklad [387]

Answer:

The wick absorbs the liquid wax and pulls it upward. The heat of the flame vaporizes the wax, and it is the wax vapor that burns. ... It continues to form as long as the wick is hot enough to vaporize paraffin. If you touch a lit match to the stream, a flame will run down it and re-light the wick.

Chargaff's analysis of the relative base composition of DNA was significant because he was able to show that
ArbitrLikvidat [17]

Answer:

C) The amount of A is always equivalent to T, and C to G

Explanation:

Chargaff's rule was given by the Austrian chemist, Erwin Chargaff in late 1940s. It explains the composition of the four bases i.e. Adenine(A),  Guanine(G), Thymine(T) and Cytosine(C) in a DNA molecule. According to it, purine and pyrimidine bases are always found in 1:1 ratio in a DNA molecule. A and G are purine and T and C are pyrimidine bases and a purine always forms a pair with pyrimidine base hence the amount of A will always be equal to T and amount of G will always be equal to C. This rule forms the basis for the Watson and Crick pairs in DNA double helix model.
