Answer:
Carbohydrates, Nucleic acids, Proteins, and Lipids
A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2:1.
Nucleic acids are bio-polymers, or large bio-molecules, essential for all known forms of life.
Proteins are large bio-molecules, or macro-molecules, consisting of one or more long chains of amino acid residues.
In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others.

Answer:
Genetic variation
Explanation:
Darwin studied that different populations of finches on Galapagos island that are descended from the same species. Some species are evolved to eat nuts and large seed, some eat small seeds and some feed on insects and nectar.
So genetic variation occurred in different populations of finches which enabled them to bring changes in their beak according to the food resource they have chosen to feed on.
So in Darwin's finches, genetic variation leads to new species which is a type of natural selection. Therefore subset of finches that can feed on large seeds and small seeds is an example of genetic variation.
