Respuesta :
Stem cells are the specific kind of cells that have the ability to develop into a cell of another type like the nerve cell, brain cells, heart muscle or bone. They also have the quality or regeneration or self renewal which will renew them into new cells again. It is this quality that interests the scientists world over to research on stem cells
They try to find new ways to study stem cells to understand the emergence of regenerative diseases and the cure for such diseases. The property of generating new cells helps in bone marrow transplants. The cells have the property to change into a different type of cell which will help scientists develop a desired type of cell to test new drugs.
Hence the first and fourth statements are the ones that are true
Statement 2 does not apply because stem cells are the cells that can be developed into any other type of cell
Statement 3 does not apply because humans also have stem cells
Statement 5 does not apply because all cells go through cell differentiation
