What does the lack of genetic diversity imply about the history of the cheetah population?

The lack of genetic diversity implies that the history of the cheetah population was relatively "calm" and undisturbed; in other words, there weren't crazy environmental stimuli and changes. The reason for this is based on the fact that the population had a lack of genetic diversity, as fewer genetic diversity means less of an ability to adapt to environmental stimuli/changes.

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.
