What are the sub components of each of the 4 types of macromolecules

The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Explanation:

1) Carbohydrates contain three elements; carbon, hydrogen and oxygen in ratio 1:2:1. Monosaccharides - the simplest form of carbohydrates, contains one sugar example is glucose.

2) Lipids are made up of four major components: fatty acids, a glycerol component, and both a phosphate group and a polar molecule.

3) Proteins are made up of different arrangements of the same 20 kinds of amino acids. Amino acids are the building blocks that make up proteins, which consists of a central carbon atom bonded to an amino group (–NH2), a carboxyl group (–COOH), and a hydrogen atom.

4) Nucleic acids are made up of three components: a purine or pyrimidine nitrogenous base, a pentose sugar, and a phosphate group. The substructure consisting of a nitrogenous base and a sugar molecule is called a nucleoside.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
