Proposes that before adopting a new health behavior an individual considers his vulnerability to the problem, the seriousness of the problem, and the effectiveness of the new behavior for reducing the risk or preventing the problem emphasizes that people and their environment interact continuously, each influencing the other considers an individual’s intention to change behavior to be determined by both personal attitudes and subjective norms focuses on the process by which an idea or behavior spreads throughout a population assumes that new behavior change involves a series of different steps through which people must move. a. theory of planned behavior b. health belief model. c. stages of change model. d. social cognitive theory. e. diffusion of innovation model.

The herpes viruses are important enveloped dna viruses that cause disease in vertebrates and in some invertebrates such as oysters. some of the human forms are herpes simplex virus (hsv) types i and ii, causing facial and genital lesions, and the varicella zoster virus (vsv), causing chicken pox and shingles. each of these three actively infects nervous tissue. primary infections are fairly mild, but the virus is not then cleared from the host; rather, viral genomes are maintained in cells in a latent phase. the virus can later reactivate, replicate again, and infect others. in electron micrographs of hsv infection, it can be seen that the intact virus initially reacts with cell surface proteoglycans, then with specific receptors. this is later followed by viral capsids docking with nuclear pores. afterward, the capsids go from being full to being "empty." which of the following best fits these observations? a) viral capsids are needed for the cell to become infected; only the capsids enter the nucleus. b) the viral envelope is not required for infectivity, since the envelope does not enter the nucleus. c) only the genetic material of the virus is involved in the cell's infectivity, and is injected like the genome of a phage. d) the viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus.
