What is a stem cell? a cell from which a new cell that has a specialized function is formed a mature egg cell that is capable of forming a new organism a cell that has half the number of chromosomes of a parent cell a specialized cell in the skin that identifies pathogenic organisms?

The correct answer is-  a cell from which a new cell that has a specialized function is formed.

Stem cells can be described as the undifferentiated cells ( with no specific function) in the body that develop into specific cell type ( such as muscle cell, neurons that have specialized function) through a process of differentiation.

They are found in adults ( in certain tissues like bone marrow, blood, and adipose tissue) as well in the developing embryo ( can be extracted from the inner cell mass).

They play significant role in the repair of damaged tissues ( as new cells with specific functions can be produced from them), also involved medical therapies ( for example transplantation of bone marrow) and other areas.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
