Organisms with hard parts stand a good chance of being fossilized if they are rapidly eaten by scavengers slowly buried by sediments rapidly buried by sediments rapidly decomposed by bacteria

rapidly eaten by scavengers  - eaten means nothing left

slowly buried by sediments  - slowly buried it could escape or be damaged

rapidly buried by sediments  - right answer

rapidly decomposed by bacteria - decompose means nothing left

rapidly buried by sediments  - right answer

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.
