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.

Prophase

Metaphase

Anaphase

Interphase

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

Chromosomes condense

Spindles enter nucleus

Centrioles move toward poles

Crossover occurs

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.

Formation of cleavage furrow

Separation of cytoplasm

Division of chromosomes

All of the above

Mitosis creates two diploid cells

Meiosis creates two diploid cells

Both happen in somatic cells

Mitosis increases genetic diversity
