What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infect

Simora [160]

Answer: Sterilization.

Explanation:

Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.

Since sterility cannot be demonstrated without causing the complete destruction of the products, <u>sterility is considered when the probability of a product being contaminated is acceptably remote.</u> A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).

Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than <u>after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.</u>

Examples of sterilization include physical methods and chemical methods. Physical methods include:

Wet heat (in steam autoclave)
Dry heat (in sterilization oven)
Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)

Chemical methods include a variety of chemicals in liquid and vapor form, for example:

Hydrogen peroxide
Chlorine dioxide
Ozone gases
Ethylene oxide
Propylene oxide
Peracetic acid

vitfil [10]

Answer:

The correct answer is -

Decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

NO effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

Increase plant growth - increase CO2, increase sunlight, increase H2O

Explanation:

Decrease in exposure of sunlight to the plant or less intense light will affect the production of oxygen and glucose negatively which affect the growth of the plant. Decrease CO2 will be affect the growth of the plant similarly as light and water molecules which is decreased in plant growth.

Increase in the in production of the products which are 02, glucose, will have no effect in plant growth though increase in the carbon dioxide, water, and sunlight will positively affect plant growth.

Thus, the correct answer is - decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

no effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

increase plant growth - increase CO2, increase sunlight, increase H2O
