2) tumor growth
3) frequent apoptosis
4) fast cell division

Answer 1

Answer:

depending on the type of cell ,then are divided - mitosis and and moeisos.

Answer 2

The correct solution is Option A, Lack of cell division.

• The G0 phase (also known as the G zero phase) or resting phase is a stage of the cell cycle during which cells are dormant.
• The G0 phase can be thought of as either an extended G1 phase in which the cell is neither dividing nor preparing to divide or a distinct quiescent period outside of the cell cycle.
• For Examples, When neuron and heart muscle cells achieve maturity (i.e., when they are terminally differentiated), they become quiescent, yet they continue to fulfil their primary roles throughout the duration of the organism's life.
• The G0 stage is also applied to multinucleated muscle cells that do not undergo cytokinesis.
• From a cell cycle checkpoint in the G1 phase, such as the restriction point (animal cells) or the start point (human cells), cells enter the G0 phase (yeast).
• This usually happens when there aren't enough growth factors or nutrition.
• The cell cycle machinery is destroyed during the G0 phase, and cyclins and cyclin-dependent kinases vanish.
• Cells remain in the G0 phase until a reason to divide presents itself.
