1 This produces a vertical stretch, where the $\,y$-values on the graph get multiplied by $\,2\,$.  Replace every $\,x\,$ by $\,5x\,$, giving the new equation [beautiful math coming... please be patient] $\,y=2{\text{e}}^{5x}\,$.
The human body contains many natural polymers, such as proteins and nucleic acids. Cellulose, another natural polymer, is the main structural component of plants. Most natural polymers are condensation polymers, and in their formation from monomers water is a by-product.
Cellulose is a long chain of linked sugar molecules that gives wood its remarkable strength. It is the main component of plant cell walls, and the basic building block for many textiles and for paper. Cotton is the purest natural form of cellulose.
