The human tooth has a natural protective mechanism. This mechanism may act against bacterial colonization that complements the defensive role of saliva. The hard enamel part of the tooth selectively absorb acidic glycoproteins from saliva and it is referred to as mucins. This results in the formation of a membranous layer known as the acquired enamel pellicle, which confers a net negative charge. Most bacteria possess a net negative charge, thus there will be repulsion between the tooth surface and the bacteria. Dental plaque is formed when the natural protective mechanism fails.

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.
