The table below identifies three classes of genes that affect the cell cycle. gene type gene activity proto-oncogenes regulate progress though the normal cell cycle oncogenes cause uncontrolled cell cycle progression tumor suppressor genes restrict cell cycle progression which scenario transforms normal cells into cancer cells? tumor suppressor genes become pro-oncogenes. tumor suppressor genes become oncogenes. proto-oncogenes become oncogenes. oncogenes become proto-oncogenes. description

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
