Final answer:
Bacteria have specific temperature preferences for growth. Mesophilic bacteria, found in human microbiota and pathogens, grow best at moderate temperatures between 20°C and 45°C. Bacteria that grow best at room temperature should always be incubated at room temperature, while those that prefer body temperature should be incubated at 37°C.
Step-by-step explanation:
Bacteria has preferred growth temperatures where their reproduction rate is the greatest. The range of optimal temperatures for bacterial growth depends on the specific type of bacteria. Mesophilic bacteria, which include many human microbiota and pathogens, prefer moderate temperatures between 20°C and 45°C. Bacteria that grow best at room temperature should always be incubated at room temperature, while bacteria that grow best at body temperature should be incubated at 37°C.
