What is a prototype? A prototype is a design tool used to help create a new product, much like a model. There are different kinds of prototypes; some are more like rough drafts and some are more like the final version. When you first come up with an idea for a new product, you'll probably sketch it out so you can show people what you're thinking of: This is one version of a prototype. But as time goes on, you'll want to make your drawing more detailed, especially if you're thinking about creating a complicated system.
Definition of sneeze. sneezed. ; sneezing. intransitive verb. : to make a sudden violent spasmodic audible expiration of breath through the nose and mouth especially as a reflex act.
Sneezing is a reflex of the upper airways, activated to explosively discharge irritating material from the nasal cavity. In cats, it is usually caused by the irritation of sensitive nerve endings in the mucous membrane that lines the nose. Nasal discharge is another sign of nasal disease or irritation. Although normal cats may occasionally sneeze or have nasal discharge (similar to human beings), severe, chronic or recurrent bouts of sneezing or nasal discharge suggest a more serious problem. Sneezing and nasal discharge often occur together.
