The most important difference is the order in which the elements are connected together, the functional groups as we say in chemistry. C,H and O can be arranged (in differing numbers) to make alcohols, aldehydes, ketones, acids and esters, to name just the obvious ones. When it comes to macromolecules you can get carbohydrates and fats for instance. The number of atoms also matters, so you can get many different examples within each class.
Bronze is an alloy composed of mainly copper and tin. It is not a pure substance, as it is made by combining different elements.
Grains consist of carbohydrates mainly. There can be others too
Mainly enzymes are involved. They are made up of proteins
No, but most macromolecules are organic molecules (with a backbone made of carbon atoms). But it is possible to synthetically create macromolecules with a backbone made of silicon atoms (i.e. the silicones), boron atoms (i.e. the boranes), and a few others. The atoms attached to the backbone or forming side branches extending away from the backbone can be any element on the periodic table.
A compound is made up of two or more different elements that are chemically bonded together. Each compound has a fixed ratio of elements and distinct properties different from its individual elements.
Stars are made from a lot of different elements, but when they are done they are mainly hydrogen and helium.

Molecules of carbons are known as orgains. Since carbon is the main atom of carbohydrates, proteins and other macromolecules they are said to be organic. There is no in organic macromolecules exist in our cell.

Because of gravity, the Earth's inner layers consist of the heavy elements, mainly metals. The heavy and radioactive ones are the origin of most of the heat.
All elements are made of atoms.
Grains consist of carbohydrates mainly. There can be others too
Fats are made of the same elements as carbohydrates, but in different proportions.
Mainly enzymes are involved. They are made up of proteins
Mainly hydrogen and helium with other trace elements.

Yes you can be allergic to sequins. Mainly a sequin will be made of plastic but the colored coating that makes it "sparkle" or "shine" is made up of different metallic elements within the color or paint used on them. That is what you are reacting to.
