4. corn kernels have an outer endosperm and an inner endosperm. a purple outer endosperm is dominant to a colorless (clear) outer endosperm. a yellow inner endosperm is dominant to a white inner endosperm. the inner endosperm color is not seen if the outer endosperm color is the dominant form. if the outer color is recessive or suppressed, the inner color is visible. in addition, the purple outer endosperm gene is suppressed and not expressed when a dominant color suppressor gene is present.

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.
