Mitosis and Meiosis

What phase of mitosis is occuring in the picture?

• Prophase
• Metaphase
• Cytokinesis
• Telophase

What is the first phase of Mitosis?

• Prophase
• Metaphase
• Anaphase
• Telophase

Why do we need meiosis?

• To double the number of chromosomes going into sex cells
• To halve the number of chromosomes going into sex cells
• To triple the number of chromosomes going into sex cells
• To not change the number of chromosomes going into sex cells

The result of meiosis is:

• two diploid cells
• two haploid cells
• four diploid cells
• four haploid cells

A human zygote should have _____ chromosomes inside.

• 46
• 23
• 92
• 64

This picture shows which process? 

• mitosis
• meiosis
• the cell cycle

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.
• In order for the cell to be able to increase in size.
• In order for the DNA to be contained in the nucleus.
• In order for the cell to re-order the DNA sequencing in the new cells.

Put the following stages of mitosis in order: anaphase, prophase, metaphase, and telophase. 

• prophase, metaphase, telophase, anaphase
• prophase, anaphase, metaphase, telophase
• prophase, metaphase, anaphase, telophase
• prophase, telophase, metaphase, anaphase
