Final answer:
Dry-heat and moist-heat sterilization methods are used to control microbial growth. Dry-heat sterilization involves high heat for a longer period of time, while moist-heat sterilization is more effective. Heat kills microbes by altering membranes and denaturing proteins.
Step-by-step explanation:
Both dry-heat and moist-heat sterilization methods are used for controlling microbial growth. Dry-heat sterilization involves direct application of high heat or using a dry-heat sterilizer, such as an oven, for a longer period of time. Moist-heat sterilization, on the other hand, is typically more effective as it penetrates cells better. Heat can kill microbes by altering their membranes and denaturing proteins, making it a widely used method for microbial control.
