c 18.5% black o 65% red p 1.0% pink k 0.4% brown
h 9.5% yellow n 2.5% blue s 0.3% green ca 1.5% purple

1. what are the 4 main elements that make up 95% of a living organism?

part b: preview the text, carbon compounds and answer the following questions from the text.

1. whats the big deal about carbon? how many valence electrons does carbon have?
2. what types of bonds does carbon form?
3. define macromolecule

Explanation:

1. The four main elements that make up 95% of a living organism are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N) as they are fundamental for biological molecules like proteins, carbohydrates, lipids, and nucleic - acids.
2. Carbon is important because it can form stable covalent bonds with other carbon atoms and a variety of other elements, allowing for the formation of diverse and complex organic molecules. Carbon has 4 valence electrons, which enables it to form up to 4 covalent bonds.
3. Carbon forms covalent bonds, including single, double, and triple covalent bonds. This allows for the creation of straight - chain, branched - chain, and ring - shaped molecules.
4. A macromolecule is a very large molecule, typically formed by the polymerization of smaller subunits (monomers). Examples include proteins, nucleic acids, carbohydrates, and lipids.

Answer:

1. Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N)
2. It can form diverse and complex organic molecules; 4 valence electrons
3. Single, double, and triple covalent bonds
4. A very large molecule, typically formed by the polymerization of smaller subunits (monomers)
