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.
Methyl cellulose. Methyl cellulose (or methylcellulose) is a chemical compound derived from cellulose. It is a hydrophilic white powder in pure form and dissolves in cold (but not in hot) water, forming a clear viscous solution or gel.
