Question

a scientist observes a tissue sample with cells that divide continuously and do not respond to signals. what can be inferred? the cells are undergoing normal cell cycle control the cells have lost regulation and may be cancerous the cells are in the resting (g₀) phase the cells are performing apoptosis

Explanation:

Cancer cells are characterized by uncontrolled growth (continuous division) and a lack of response to normal regulatory signals. Normal cells have strict control over the cell cycle and respond to signals (like growth - inhibiting signals). Cells in the resting ($G_0$) phase are not dividing. Apoptosis is a programmed cell - death process, which is a controlled event. Since the observed cells divide continuously and do not respond to signals, they are likely cancerous.

Answer:

The cells have lost regulation and may be cancerous.
