Why should you never rub a frozen body part?
When a body part freezes, ice crystals form. If you rub the body part, the ice crystals will pierce the cells and damage them.
What happens to cells during frostbite?
The cells will freeze, and likely die, especially when accompanied by rubbing when frozen.
Why do you never rub someone that has just received frostbite?
If someone has frostbite, which means that their flesh is frozen, the expanded ice crystals inside the cells of the skin, muscle, blood vessels, etc will grate together and break down the cell walls if you rub it. Think about taking a frozen cut of meat, then rubbing a corner of it. The tissue would begin to break down, you would eventually end up with a pulpy mass. If you think you have frostbite, get medical attention to save the toe/limb/frozen area.
Why food does not spoil in the freezer?
The chemical and biochemical reaction that cause spoilage are slowed down to the point they effectively stop. Many microorganisms are killed at these temperatures as ice crystals burst their cells (but these ice crystals also burst cells in the food, which causes other damage that degrades the quality of frozen foods).
Why would freezing your cells damage them?
Because there is water in the cell. Water would form crystals as it freezes. These crystals interrupt the membranes and other organelles in the cells. They look okay while frozen, but once thawed, the cells cannot maintain their integrity any more. There are certain animal, I think a type of frog, that can handle freezing and thawing.
Which does not belong Cells growth youth and crystals?

What doesn't belong crystals cells energy use growth?
crystals
How does the location affect the brownness of a banana?
The cells break down faster in the cold they do best at room temperature). They can however be frozen with no ill effects.
What happens when the blood reaches tissues or cells that do not have enough oxygen?
The oxyhaemoglobin will break down and oxygen will release. :)
What happens to cells at the edge of an injury when a cut in the skin or a break in a bone occurs?
When a person breaks a bone or has a cut, the cells at the edge of the injury are stimulated to divide rapidly. The new cells that form begin to heal the break or cut. As it heals, the cells stop dividing and growing.
Does frostbite kill cells?
Yes, ice crystals form and burst the cells.
What happens to the cell at the edges of an injury a cut in the skin or a break in a bone occurs?
