Answer 2

Hello. This question is incomplete. The complete question is:

"Which of the following describe a stem cell? Check all that apply. a cell that is able to develop into a variety of specialized cells a cell that is able to self-renew from differentiated cells a specialized cell that results in differentiation a specialized cell that results in self-renewal a cell that divides by meiosis to produce new cells "

Answer:

• a cell that is able to develop into a variety of specialized cells
• a specialized cell that results in differentiation

Explanation:

Stem cells are very special cells. They appear in the human being, still in the embryonic phase, before birth. After birth, some organs still hold within themselves a small portion of stem cells, which are responsible for the constant renewal of this particular organ. These cells have some distinct characteristics:

• they can reproduce themselves by duplicating themselves, generating two cells with equal characteristics; furthermore it is a cell that is capable of transforming itself into a variety of specialized cells
• they can differentiate, that is, transform themselves into several other cells of their respective tissues and organs.

An example is the hematopoietic stem cell, which in adults is located in the red bone marrow. In the bone marrow, it is responsible for the generation of all blood.

This is the cell that is effectively replaced when a bone marrow transplant is performed.
