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 Electoral College came out of a compromise in 1787, and as a result, American citizens have indirectly elected the President ever since. The Constitution alloted each state a number of electors based on the combination of each states' members in the House of Representatives (determined by population) and adding each states' two Senators. In order to win the election, a candidate must obtain a quorum (half plus one) of the total votes cast by the College delegates. Today, there are 538 Electoral College votes, with 270 being the "magic number" needed to win.

Some of the delegates in Philadelphia wanted to elect the president by popular vote, while other delegates favored having the president elected.
