Hello!
The type of polymer that is made by bonding an alkene to one or more alkanes or alkenes is called addition polymer
Addition polymers are those whose polymerization reaction doesn't produce low molecular mass compounds but the bonding of molecules one after the other. Such a reaction implies that there is a rupture in the bonding between monomers (the building blocks of the polymer) to allow the formation of a chain.
Bonding an alkene to one or more alkanes or alkenes is an example of an addition polymerization.

Answer: c) genes that have specific DNA structures genes that make molecules of cellular structures.
Explanation:
The structural genes are the form of genes that encode for proteins in the body that are required for performing specialized function in the body of the organism. The proteins are the building blocks of the cells. These genes encodes for the amino acid sequence for the synthesis of protein. These proteins create a physical structure inside the cells of the organism such as cytoskeleton, which gives the cells it's shape.
Fern is the answer because it dosen't have seeds
