Introduction To Microbiology (Mcb 112)

Explanation
Abiogenesis refers to the now-discredited theory that living organisms can arise spontaneously from inanimate matter. This theory was widely accepted until the 19th century when Louis Pasteur's experiments disproved it and supported the concept of biogenesis, which states that living organisms can only arise from pre-existing living organisms. Therefore, Abiogenesis is the correct answer as it accurately describes the concept of spontaneous generation.

Explanation
The correct answer is 15 minutes and 1210. Sterilization in an autoclave is achieved by subjecting the items to high pressure and high temperature. The combination of 15 minutes and 1210 degrees Fahrenheit is the most effective in killing all microorganisms and achieving sterilization.

Explanation
Robert Koch injected pure cultures of bacilli into mice which causes Anthrax disease.

Explanation
The correct answer is Germ theory of Dx. The germ theory of disease states that microorganisms, such as bacteria and viruses, are the primary causes of infectious diseases. This theory was developed by Louis Pasteur and Robert Koch in the late 19th century and revolutionized our understanding of how diseases spread and can be prevented. It led to advancements in hygiene, sterilization techniques, and the development of vaccines and antibiotics to combat infectious diseases.

Explanation
Sterilization is the correct answer because it refers to the process of completely killing or eliminating all microorganisms, including bacteria, viruses, and fungi. This process is commonly used in healthcare settings, laboratories, and food preparation industries to ensure the complete removal of any potential pathogens or contaminants. Disinfection, pasteurization, and sanitization are all related processes but do not guarantee the complete elimination of all microorganisms like sterilization does.
