The above picture represents the different stages a cell goes through in its "lifetime." each phase is characterized by specific events. cells that are fully differentiated spend most of their time in g0. what event or events characterize this phase? a) it is the period of cell death. all activities stop. b) it is a resting phase where the cell has left the cycle and has stopped dividing. c) this is the first growth phase within interphase and the number of proteins increases. d) this is a period of protein synthesis and rapid cell growth to prepare the cell for mitosis.

The correct answer is option (B) It is a resting phase where the cell has left the cycle and has stopped dividing.

Cell cycle refers to a series of events taking place in a cell leading to its division and duplication. Normally the stages of a cell cycle is divided into four phases namely the G1 phase, S phase (synthesis), G2 phase (interphase) and M phase (mitosis or meiosis). But the cells that have stopped dividing temporarily are said to enter a phase of quiescence called the G o phase.

G o phase refers to a non-dividing cellular phase outside the replicative cell cycle. The cell cycle beings with G o phase. This can also occur due ot DNA damage or the external environmental stress. G o phase is categorized into reversible G o phase as in case of mature liver cells, stem cells and irreversible G o phase as in differentiated cells of bone, muscle and nerve.

Thus, G o phase is a resting phase where the cell has left the cycle and has stopped dividing.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

sex cells are usually half's then they find another half and make a fertilize egg
