. How can evolutionary relationships among organisms be determined by comparing embryonic development?

A. Embryos of fish and mammals share no similarities.

B. Embryos retrace their ancestral stages during embryonic development.

C. Embryos of more closely related organisms show greater similarities in development.

D. Embryos that develop inside eggs lack similarities to placental mammals.

the answer to your question is b

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.
