What is the difference between the genetic material on two sister chromatids and the genetic material on homologous chromosomes ?

sister chromatids carry identical genetic material, either from a maternal or paternal source, as they are intended to be perfect copies distributed into different daughter cells. Homologous chromosomes, on the other hand, contain both a paternal chromosomes and maternal chromosomes.

Explanation:

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.
