The diagram shows the process of cell specialization from a single stem cell. Which of the following statements is true about the process of specialization.

• Specilized cells (blood, skin, nervous etc) cannot be produced from a single stem cell
• Specilized cells are produced immediately following fertilization
• Even though all the cells in an organism come from one single cell, they can specialize into different cell types
• Sincce all the cells in an organism come from one single cell, they must all have the same structure and function

In what way is the DNA of a nerve cell different from the DNA of a muscle cell?

• The DNA is the same but each cell contains different genes
• The DNA is the same but different genes are turned on in each cell
• Each cell has its own unique DNA
• The DNA is different, but each cell contains the same genes

stem cells are defined as 

• a cell that has the ability to divide only once and stay the same as other kinds of cells 
• A cell that has the ability to continuously divide and differentiate into various other kinds of cells/tissues
• any cell of a living organism other than the reproductive cells
• a cell that contains a nucleus surrounded by a membrane and whose DNA is bound together by proteins
