Which is not true of cancer cells? a) cancer cells fail to undergo apoptosis. b) cancer cells exit the cell cycle and enter the g0 phase. c) cancer cells ignore signals that should cause them to stop dividing. d) cancer cells can migrate to other parts of the body through the process of metastasis.

The answer is; B

G0 is the stage of the cell cycle where the cells do not divide.

Cancer cells are renegade cells whose cell cycle regulation has failed, mostly due to damage in their genetic material, hence the cells proliferate unregulated.  The checkpoints in the stages of the cell cycle fail. An example is the failure of tumor suppressor genes that suppress the action of cyclins that promote the progression of the cell cycle.

B is correct

Cancer cells are characterized by unregulated cell growth, ignoring signals that would tell them to stop dividing. Cancer cells, instead will continue to divide, often many more times than a normal cell. Cancer cells also resist undergoing apoptosis or cell death. Cancer cells can travel to other areas of the body through the process of metastasis, often causing spread of the disease. Cancer cells WILL NOT exit the cell cycle to the G0 phase. The G0 phase is a non-dividing phase.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

ya the other dude is right
