We use radiation to extend the shelf life of food by destroying organisms that cause spoilage. Do we use neutrons electrons gamma rays or alpha particles?
We use gamma rays to irradiate food and kill organisms on it that might cause it to spoil quickly.
How do hypertonic solutions kill bacteria that spoil foods?
because of the hypertonic enviornment, the bacter cannot grow and spoil the food due to lack of water
Who developed a process of heating food to kill the germs that spoil it?
Louis Pasteur invented pasteurization.
Which EM waves can kill bacteria on food and surgical tools?
EM waves like X-rays and gamma rays are efficient at killing bacteria on food and surgical tools. These are ionizing radiations and cause breaks in the DNA of the organisms. On sufficient exposure, the breaks are irreparable and the bacteria on the food and surgical tools are killed.
An antibiotic designed to kill single-celled prokaryotic organisms found in food by disabling their ability to use oxygen and suffocating them is most likely targeting organisms found in which kingdo?
Antibiotic designed to kill single-celled prokaryotic organisms found in food by disabling their ability to use oxygen and suffocating them is most likely targeting organisms found in the Eubacteria kingdom.

Why do foods like dry soup mixes remain un spoilt for many days?
Spoilage in foods is due to fungus or bacterial growth. Dried soups lack water and so form a hostile environment to those organisms. Other methods of preserving food from spoilage include adding salt, adding sugar, adding vinegar canning, or irradiating the food. These last two kill any spoiling organisms inside the food, so until the food is removed from it's sealed package it doesn't spoil.
How do you kill micro organisms?
micro organisms can kill you by causing diseases
Why cooking food helps kill microorganism?
because some micro organisms cannot live in heat.
Struggle that occurs between organisms for food water and energy when resources are limited?
The struggle that occurs between organisms for food and water and energy when resources are limited is called competition. Competition can kill animals.
