Question

question ① what does the formation of a malignant tumor indicate? answer metastasis is necessary and easy to control. the cells are remaining within a connective tissue capsule. the tumor cells resemble normal cells, but they are dividing faster. mitotic rates of cells are no longer responding to the normal control mechanisms. i dont know yet

Explanation:

• Option 1: Metastasis (spread of cancer) is not easy to control, so this is wrong.
• Option 2: Malignant tumors invade surrounding tissues, not remain in a capsule (that's benign), so wrong.
• Option 3: Malignant tumor cells don't resemble normal cells (they are abnormal in appearance and function), so wrong.
• Option 4: Malignant tumors result from cells' mitotic (cell division) rates escaping normal regulatory mechanisms, leading to uncontrolled growth. This matches the definition of malignant tumor formation.

Answer:

D. Mitotic rates of cells are no longer responding to the normal control mechanisms.
