The Koala bear scraped its leg when climbing up the tree. What is going to happen to the scrape?
Nothing - the area will never heal.
The body will make enough cells to fill in the area and heal the cut.
The body will make too many cells and there will be a lump in that area.
When the Koala bear injured its leg, it had to replace skin cells, red blood cells, and fat cells. Do all of these cells have the same DNA?
Yes
No
