Q.1
Mitosis and meiosis are processes by which animal and plant cells divide. Which statement best describes a difference between mitosis and meiosis?
Meiosis is a multi-step process
Mitosis occurs only in eukaryotic cells
Meiosis is used in the repair of an organism
Mitosis produces genetically identical daughter cells
Q.2
Use the illustration below to answer the question.
The cell is in prophase of mitosis because the number of chromosomes has doubled.
The cell is in prohpase I of meiosis because the number of chromosomes has doubled.
The cell is in telophase of mitosis because the cell is separating and contains two copies of each chromosome.
The cell is in telophase of meiosis because the cell is separting and contains two copies of each chromosome.
