Why do you think heating the lethal pneumonia bacteria in Griffith's experiment killed them?

Heat denatures the lethal pneumonia bacteria's proteins or enzymes causing them to become ineffective. Therefore, without the bacteria's proteins or enzymes functioning correctly, the lethal pneumonia bacteria die.

A luminous flame
Heating a liquid to kill harmful bacteria is called?
The use of heat to kill bacteria in food and beverages is pasteurisation
How does pasteurization preserve food?
You are heating it, which destroys the bacteria or slows the microbial growth, so less bacteria in the food, which makes it safer to eat!
Bacteria and viruses are destroyed by?
Using bactericides and when it is possible by heating.

How can you experiment buble gums?
probably by sticking it on a paper and heating it until it falls
Why a normal glass can be broke by heating it with a physical experiment?
uneven thermal expansion
How is a control useful in a scientific experiment?
A control experiment provides a benchmark against which to compare the results of the main experiment. For example, to know if heating a material changes its resistance, you must be able to compare the results of the heated experiment to a copy in which the material was left unheated.

What does pasteurize mean?
heating it to kill and bacteria in the milk making it safer to drink.It typically involve heating to 72degrees for few minutes followed by sudden cooling to 6-10degreres.Both process are important for ensuring complete killing of bacteria.
Why a luminous flame is not used as a source of heat in a laboratory experiment?
Because it makes the apparatus black when heating
