Final answer:
The simplest method of fire suppression is oxygen exclusion, typically achieved using a fire blanket or foam. Filtration is the microbial control method that physically removes microbes from samples without killing them. The first step in triglyceride degradation is the removal of fatty acids.
Step-by-step explanation:
The simplest method of fire suppression among the options given is B. Oxygen exclusion. It involves creating a barrier between the fire and the surrounding air, thereby removing the oxygen that fuels combustion. This can be done using a simple fire blanket or a layer of foam, making it a straightforward method compared to other techniques that require more complicated processes or substances.
Regarding the microbial control methods question, the method that does not kill microbes or inhibit their growth but instead removes them physically from samples is A. filtration. Filtration is a mechanical process where a porous material retains microbes while allowing the fluid or air to pass through.
The first step in triglyceride degradation is A. removal of fatty acids. This is the initial action that takes place before further degradation processes such as β-oxidation can occur.
