• Making exact replicas

• Producing energy

• Transporting oxygen

• Fighting infections

Multiple Select

• G1

• S

• G2

• M

Multiple Choice

During which parts of the cell cycle does the cell grow?

• G1 and G2
• G1 and S
• M phase and cytokinesis

Open Ended

What could happen if the DNA doesn't copy accurately during the S Phase?

Multiple Choice

What happens at the site of an injury to fill the gap?

• New cells come from old cells, which grow and split through a repeated and nonrandom process.

• When cells grow and split, they make new cells of the same type.

• A gap in the skin, muscle, or bone is filled by new cells as a result of cells growing and splitting.

• All of the above.

Multiple Choice

Chromosomes line up at the equator of the cell

Spindle fibers extend from the centrioles to the middle of the chromosomes

• Prophase

• Metaphase

• Anaphase

• Interphase

Multiple Choice

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.

Multiple Choice

How does meiosis contribute to genetic diversity?

• By duplicating chromosomes

• By ensuring daughter cells are identical

• Through crossing over and independent assortment

• By producing cells with the same number of chromosomes as the parent cell

Multiple Choice

What key event occurs during Prophase 1 of meiosis?

• Chromosomes condense

• Spindles enter nucleus

• Centrioles move toward poles

• Crossover occurs

Multiple Choice

Describe the process of anaphase I in meiosis.

• Sister chromatids separate and move to opposite poles of the cell.

• The cell divides into two daughter cells.

• The chromosomes replicate.

• Homologous chromosomes separate and move to opposite poles of the cell.

Multiple Choice

What are the key events that occur during Telophase 1 and Cytokinesis?

• Formation of cleavage furrow

• Separation of cytoplasm

• Division of chromosomes

• All of the above

Multiple Choice

What are the main differences between mitosis and meiosis based on the provided comparison?

• Mitosis creates two diploid cells

• Meiosis creates two diploid cells

• Both happen in somatic cells

• Mitosis increases genetic diversity

Interphase is the shortest phase of the cell cycle.

Cytokinesis happens after mitosis to complete cell division.

Sister Chromatids are pulled apart at the Metaphase stage.

Mitosis results in the formation of two identical daughter cells.
