Evolution occurs when nature selects:

mutations that increase reproduction

point mutations

chromosome mutations

induced mutations

The correct answer is A. Mutations that increase reproduction

Explanation:

Evolution is a natural process in life that occurs when genes and traits in a population change over time or generations. One of the main processes that cause this, is the natural selection that occurs when in a population of same organisms some traits caused by mutations represent an advantage to survive or reproduce because they make organisms more likely to survive or increase reproduce and this makes these traits be naturally selected or prevail over time. In this way, the natural selection of mutations or traits introduces new genes in a population. According to this, evolution occurs when nature selects mutations that increase reproduction.

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.
