Question

a scientist notes that some cells in a sample have stopped dividing. these cells still perform their specialized tasks. which state best describes these cells? (1 point) the cells are undergoing proliferation. the cells are entering the synthesis phase. the cells are starting the apoptosis process. the cells are experiencing senescence.

Explanation:

• Proliferation means cell division, which contradicts the cells having stopped dividing.
• The synthesis phase (S - phase) is part of the cell cycle where DNA is replicated, and cells in this phase are still in the cell - division process.
• Apoptosis is programmed cell death, and cells undergoing apoptosis do not just stop dividing while still performing specialized tasks.
• Senescence is a state where cells stop dividing but remain metabolically active and can still perform their specialized functions.

Answer:

The cells are experiencing senescence.
