Bacteria like Archaebacteria can survive in extreme temperatures but eubacteria cannot. Since Eubacteria die from the harsh temperature and Archaebacteria cannot reproduce your immune system kills all of the Archaebacteria. That is why freezing in a technical sense stops bacteria from reproducing.
the effects of freezing baceria is that bacteria stops growing as the conditions aren't suitable
Freezing food SLOWS the action of bacteria
the bacteria dies
The effect would be that the bacteria and fungi would rot dead
Freezing food slows or stops the action of bacteria
Yes, bacteria can survive freezing temperatures. Freezing isn't a sure-fire way to kill the bacterial population in the food. The only thing freezing will do is halt the multiplication of bacteria however thawing will resume the process.
Freezing should have an effect on amylase. Amylase is an enzyme, which is therefore a protein, and has optimum conditions. Freezing it will severely slow it down, and I'm pretty sure will denature it, so yes it will completely reduce if not stop the effect of amylase. Freezing does not denature enzymes, heat does.
It will affect the growth of the bacteria.

Freezing does kill the bacteria because it freezes the cell movement. Bacteria has to maintain in movement to stay alive. Also when it freezes, it shatters easily. This kills the bacteria almost immediately.
Freezing doesn't effect the enzymes since freezing does not permanently affect enzyme structure. Boiling permanently changes the structure and can change the enzymes.
It lowers the freezing point.
No, it doesn't kill much of the bacteria at all and the bacteria remaining will grow during defrosting.
freezing provides unsuitable temperature for activities of enzymes

no

Freezing bacteria doesn't kill it. It 'slows' it down. When I mean 'slows' it down I mean that by it going to sleep or something. as soon as the bacteria defrosts, it comes back to life.
