Irritability is the response to the environment. Metabolism is the ability to utilize nutrients. Reproduction is the ability to group together to form colonies or the ability of individual cells to become larger. Motion is the ability to move from place to place.

Answer to Question 2

B
Feedback:
Several antigens are tested at one time, with each antigen injected intradermally or applied to a small scratch on the skin (epicutaneous method). These areas are then labeled or otherwise identified. After 20 minutes, the provider reads the skin tests in much the same way as in a tuberculin test. Erythema (redness) and, most commonly, an induration (a lump, wheal, or edema) indicates a positive skin test.
