Question

which of the following is true of malignant tumors?
they can cause tumors in other parts of the body.
they do not require treatment.
the contain cells that stay clustered together.
they are easily removed through surgery.
put the following in correct order.
c > a > b > d > e > f
a > b > c > d > e > f
f > d > c > e > b > a
a > f > d > c > e > b

Explanation:

• Malignant tumors have cells that can break away and spread (metastasize) to other parts of the body, forming new tumors. Benign tumors, on the contrary, have cells that stay clustered together. Malignant tumors require treatment (like surgery, chemotherapy, radiation), and they are not easily removed as they can infiltrate surrounding tissues.
• For the cell - cycle order:
• A represents interphase (cell growth and DNA replication).
• F represents prophase (chromosome condensation, nuclear envelope breakdown).
• D represents metaphase (chromosomes line up at the equator).
• C represents anaphase (sister chromatids separate).
• E represents telophase (new nuclear envelopes form).
• B represents cytokinesis (cell division into two daughter cells).

Answer:

• First question: They can cause tumors in other parts of the body.
• Second question: A > F > D > C > E > B
