Mitosis and Meiosis

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. 

Dante wants to match the types of cells with how they are produced. Which choice correctly matches a type of cell with how it is produced? 

• Egg cell --> meiosis in males 
• Sperm cell --> mitosis in males
• Body cell --> mitosis in females
• Body cell --> meiosis in females

• A body cell made from mitosis 
• A body cell made from meiosis 
• A reproductive cell (sex cell) made from meiosis

How is meiosis related to sexual reproduction?

• Meiosis allows the offspring produced during sexual reproduction to grow and develop.
• Meiosis joins together the sex cells during sexual reproduction to produce new offspring
• Meiosis produces the sex cells that join to form new offspring during fertilization.
• Meiosis produces the body cells that join to form new offspring during fertilization.

During a lab experiment, Rahul looks at six unlabeled slides showing different stages of the cell cycle. The teacher asks Rahul to place the slides in order, starting with Interphase. In what order should Rahul place the slides? 

• Interphase --> prophase --> anaphase --> metaphase --> telophase 
• Interphase --> anaphase --> metaphase --> prophase --> telophase 
• Interphase --> telophase --> anaphase --> metaphase --> prophase
• Interphase --> prophase --> metaphase --> anaphase --> telophase

• It produces offspring genetically identical to each other and requires two parents.
• It produces offspring genetically different from each other and requires one parent. 
• It produces offspring genetically different from each other and requires two parents.

A group of scientists test three different types of cells – muscle cells, nerve cells, and skin cells – to find out which cell type goes through the steps of mitosis the fastest. The scientists time 100 cell divisions for each type of cell. The temperature and amount of light is the same for all of the cells. What is a controlled variable (or constant) in this investigation? 

• The speed of the divisions 
• The types of cells
• The temperature
• The age of the scientists
