1. which of the following lists includes the phases of mitosis in the correct sequence?

a)prophase, metaphase, telophase, anaphase c)telophase, prophase, metaphase, anaphase
b)prophase, metaphase, anaphase, telophase d)anaphase, metaphase, prophase, telophase

1. during the metaphase of mitosis, chromosomes

a)line up between the centrioles. c)migrate to opposite poles of the cell.
b)unwind to form chromatin. d)are selectively released from the cell.

1. apoptosis is

a)a form of secretion. c)an abnormal form of development.
b)a form of cell division. d)a form of cell death

1. during the metaphase of mitosis, chromosomes line up between the two centrioles.

a) true
) false

1. the phases of the cell cycle are

a)interphase, mitosis and cytokinesis. c)prophase, metaphase, anaphase and telophase.
b)interphase, mitosis and meiosis. d)intraphase, meiosis and telophase.

Explanation:

1. A hypertonic solution has more dissolved particles than the cell's interior.
2. Active transport moves substances against their concentration gradient, requiring cellular energy (ATP), unlike passive processes.
3. Active transport relies on specific carrier proteins to move substances across the cell membrane.
4. Phagocytosis is "cell eating," where white blood cells engulf particles/debris via organelles like lysosomes.
5. Mitosis proceeds in the order: Prophase (chromosomes condense), Metaphase (chromosomes align), Anaphase (chromosomes separate), Telophase (nuclei reform).
6. In metaphase, chromosomes align along the equator between the two centrioles (spindle poles).
7. Apoptosis is defined as programmed, controlled cell death.
8. In metaphase of mitosis, chromosomes line up at the metaphase plate, which is between the two centrioles at opposite poles.
9. The main phases of the cell cycle include interphase (growth/prep), mitosis (nuclear division), and cytokinesis (cytoplasmic division).
