Mitosis and Meiosis

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.
• different from the starting cell and different from each other.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to each other.

In which phase of the cell cycle does this occur:

Stage of intense cell growth and activity.

• G1 stage

• S stage

• Metaphase

• Prophase

How is the number of chromosomes in a human sex cell different from the number in a human body cell? 

• A sex cell has 23 chromosomes and a body cell has 46. 
• A sex cell has 46 chromosomes and a body cell has 23.
• A sex cell has chromosomes that are half
• A sex cell has chromosomes that are twice as long as those in a body cell.

• somatic cells

• germ cells

• skin cells
• all cells
