Question

Which region of the skin supports the largest bacterial population?
A)armpits
B)scalp
C)forearms
D)feet
E)All of these support similarly sized bacterial populations.

The armpits have a dense concentration of sweat glands and hair follicles, which provide a favorable environment for bacterial growth. This area also tends to be warm and moist, which further supports bacterial proliferation. Therefore, the armpits support the largest bacterial population compared to the other regions listed.
