Complete the sentence by selecting the correct answer. Darwin's idea of evolution suggested that… A Evolution does not happen in a straight line, but in many branches.
B Evolution happens in a straight line, with occasional divergents.
C Many organisms evolved from one specimen known as 'Archaea'.
D Variation occurs only in small populations. The variation leads to evolution over time.

I am 99% the answer is A. Darwin did not discover Archaea, Evolution does NOT happen in a straight line, and variation is totally different than evolution.

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.

it's a.true. i'm kind of smart.
