Betty is a professional high diver and takes a vacation to a beach she has not visited before. while there, she notices a tall cliff, which she thinks would make an excellent place to practice her diving. which of the following statements about this situation is false? a. it would be safer for betty to practice at home since she is unfamiliar with the area. b. it would be perfectly safe for betty to swim around and make sure the water is deep enough. if she finds that it is, the cliff could be a good place to practice. c. betty could check in town to see if there are any group tours that include supervised cliff diving, instead of diving alone. d. betty could do some research about the area and see if it is a common cliff for diving. if she finds that it is safe, she could then plan another trip with a group of fellow divers to practice at the cliff.

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.
