Because the microwave vibrates the water molecules in the food, heating it up.
After being defrosted, frozen foods must be cooked before being re-frozen.
To insure thorough cooking of the food item.
I am a chef and I think I know how to answer this. YES! Yes you can cook defrosted food. Just as long as you defrost it ALL THE WAY. You don't want to start cooking something (like chicken) that is partly frozen. Even just a little bit frozen.
The safest place to defrost frozen food is under refrigeration. Food can be defrosted under cold water, or in the microwave (although microwave settings vary), or ideally in the refrigerator. If you are going to cook it right away, a lower setting on the oven can sometimes be used. Obviously, it depends on the type of food. Vegetables can be defrosted in the fridge, on the countertop if they are cut into pieces, or the ziploc bag can be soaked in water if you want to hasten the process. The same can be done with meat, except for the larger pieces of meat, which generally need to be defrosted in the refrigerator for 24 hours, and then brought out of the refrigerator, and left at room temperature for an hour before cooking. For smaller pieces of meat, you can defrost them in the microwave, but you have to be careful about accidentally cooking pieces on the meat. Cheese can be easily defrosted in the microwave, as long as you keep an eye on it. Instructions on frozen meat and fish packages often say to thaw in the refrigerator. That keeps it from spending too much time at room temperature where bacteria grow best. Frozen vegetables don't matter as much. If your food preparation method (recipe) allows for it, you can also put the frozen food directly into a pot for cooking, microwave it, or do it in an oven.
The defrost mode of a microwave oven turns the microwaves on and off repeatedly to reduce the power. Reducing the power reduce the chance of one part of the food becoming hot while other parts are still frozen.
Aldi is a great store to get cheap groceries at. However I would recommend caution when it comes to buying frozen foods there. I have seen them leave entire pallets of frozen food sitting outside until completely defrosted and then being returned to the freezer.
Yes, since the oven heats food by irradiating it with microwaves. Microwaves are an example of electromagnetic radiation, having a frequency lower than that of visible light.
Once foods have been defrosted you can NEVER refreeze them! The chances of gicing yourself food poisoning is very high if you do that.
In theory it can, but the food will be vaguely disgusting.

they are useful because they help you heat up stored food that has been frozen and they are harmful because you have to watch what you put in it because it can blow up.
