Two genes for the same trait are compared. which one is not an example of a mutation? a). in the first, the series is adenine followed by two thymine; in the second, adenine is followed by two thymine. b). in the first, the series is cytosine - adenine - thymine; in the second, it is cytosine - adenine - adenine. c). the first has thymine where the second has a guanine. d).the first has a series of three nucleotide bases; the other has a series of four.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
