The body is constantly replacing itself. It was once believed to be over a seven to eight year period, depending if you were male or female but biologists are hesitant to put a true time on it but rather agree that it is an ongoing process.
This is completely dependent upon the cell Type. Red blood cells regenerate at the rate of several million new cells per second; all other types generate new cells only as required.
Cells lining the digestive tract replace themselves every three days.

cells usually replace themselves after you are born. Cells change each time we grow and some stay the same.
Every 3 days.
every 90 days
Every 25 seconds
Cells that line the digestive tract reproduce more quickly because they absorb more nutrients. This is because the food travels through the digestive tract.
AnswerIt is located at the periphery of the cell near the Golgi.
need? it's all relative. I'm sure that the very first cells lacked all enzymes.Your cells need them to keep up with the competition.
Mostly Plant cells and Bacteria, often some specialised cells will have cell walls.
The cell is the functional basic unit of life, and it is the smallest unit of life classified as a living thing. Really hope this helps! :)

every six to 14 days u should have learned this in 7th grade
Cells, which are the smallest unit of living matter and are often referred to as the building blocks of life, organize themselves into tissues, which then organize themselves into organs, which then organize themselves into systems.
In general, damage to brain cells is often irreversible. This is because the cells in the brain cannot renew themselves or divide to make new cells to replace those damaged cells. However, if the brain tumor is causing damage in terms of negative symptoms (memory loss, change in personality, fatigue, illness) because of intercranial pressure, removing the tumor may in fact reverse the "damage" it created.
Cells die every second in the body. Over a million cells are made every minute in your body. This is how you heal and grow. The cells naturally renew themselves after a certain period of time and are expelled out of the body.
The traffickers themselves. Members of the UN often dedicate their espionage and military resources to closing down trafficking cells.
Nerve cells are often called neurons.
The whole skeleton? seeing as the longest lasting cells are only replaced every 7 years i would bet a hefty 7 years to replace the whole skeleton :)
Nerve cells are often called neurons.
In terms of overall cells, it would be your skin cells, just from the sheer amount of skin. In terms of how often the cells reproduce, that would be the lining of your stomach. The hydrochloric acid in your stomach eats away at your stomach lining quickly, so your body must rapidly replace them.
AnswerIt is located at the periphery of the cell near the Golgi.
Skin cells are damaged faster than your liver cells so the divide more often
