Answer to Question 1

A
Feedback:
Ringworm is caused by a fungal infection. Fungi include yeasts and molds, which cause infections in the skin, mucous membranes, hair, and nails. Rickettsiae are microorganisms that resemble bacteria but cannot survive outside of another living species. They are responsible for Lyme disease. Protozoans are single-celled animals classified according to their ability to move. They do not cause ringworm. Helminths are infectious worms that may or may not be microscopic. They include roundworms, tapeworms, and flukes.

Answer to Question 2

B
Feedback:
Moist wounds heal more quickly because new cells grow more rapidly in a wet environment. Moisture does not necessarily inhibit bacterial growth and it does not cause cellular debris to dissolve. It is not normally desirable to have dead space in a wound filled with fluid.
