Answer to Question 1

ANS: B
Because moisture and particulate matter introduced into the blender by the source gases can cause the blender to malfunction, it is important to filter the gas before it enters the blender housing.

Answer to Question 2

ANS: D
The temperature and humidity of the gas within the incubator are regulated by a servo-controlled mechanism connected to a fan that circulates environmental gas over heating coils and a blow-by humidifier. Supplemental oxygen can be provided by connecting a heated humidifier directly to the incubator.
