Question

how does the process of mitosis support the growth and repair of organisms? (select all choices that may apply)
the separation of sister chromatids allows for cells to heal themselves.
chromosome separation results in the formation of new cells.
the division of parent cells into daughter cells increases the overall cell number of the organism.
the alignment of chromosomes along the cell equator fixes genetic abnormalities in the orgnaism.
as new cells are formed they replace those that have been damaged.

during which stage of mitosis are the sister chromatids separated?
prophase
metaphase
telophase
anaphase

Explanation:

• For the first question: Mitosis involves the division of parent cells into daughter cells. This increases the overall cell number (which is crucial for growth). Also, as new cells are formed through mitosis, they can replace damaged cells (important for repair). Sister chromatid separation is part of the process to form new cells (not directly for cells to "heal themselves" in the way described in the first option). Chromosome alignment (in metaphase) is about proper distribution, not fixing genetic abnormalities.
• For the second question: In anaphase of mitosis, the sister chromatids are separated. In prophase, chromosomes condense. In metaphase, chromosomes align at the equator. In telophase, new nuclei form.

Answer:

• First question:
• Chromosome separation results in the formation of new cells.
• The division of parent cells into daughter cells increases the overall cell number of the organism.
• As new cells are formed they replace those that have been damaged.
• Second question: Anaphase
