Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

Answer: 1. Plastics are polymers. A polymer is a substance made of many repeating units. The word polymer comes from two Greek words: poly, meaning many, and meros, meaning parts or units. A polymer can be thought of as a chain in which each link is the “mer,” or monomer (single unit). 2. Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. ... They can even join "head-to-tail" to make rings of carbon atoms. An example of two molecules that contain carbon is compound methane ( 1 carbon bounded to four hydrogen. ) ... Carbon is able to form so many molecules/compounds because each carbon atom can form four chemical bonds to other atoms and, because of its size, it fits in nicely as part of large molecules. 3. Carbohydrates- Monosaccharides (simple sugars), Lipids- Fatty acids and glycerol, Proteins- Amino acids, Nucleic acids- Nucleotides. brainliest??
