Explanation:

• Medium composition: Controlled by preparing the growth medium (like agar with specific nutrients), not the incubator.
• Temperature: Incubators are designed to regulate and maintain a specific temperature for microbial growth (e.g., 37°C for human pathogens), so this is controlled by incubators.
• Atmospheric gas: Some incubators (like CO₂ incubators) can control the gas composition (e.g., CO₂ levels) in the environment, so this is controlled by incubators.
• Sterility: Achieved through sterilization methods (like autoclaving, UV treatment) before inoculation, not by the incubator.

Answer:

B. Temperature, C. Atmospheric gas
