Answer to Question 1

D

Answer to Question 2

Three different methods can be used to quantify the behavior. (1) The frequency method would involve recording how many times each rat eats during the observation period. (2) The duration method would involve recording how much time each rat spends eating during the observation period. (3) The interval method would involve dividing the observation period into intervals (for example, one-minute intervals) and then recording whether or not each rat eats during each interval. (p. 366-367)

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
