A 3.0-kg box is given a brief push and travels 5.0 m up a plane that makes an angle of 30.0 degrees with the horizontal. The coefficient of kinetic friction between the box and the plane is 0.20. The
initial velocity of the block is
a. 5.8 m/s
b. 8.1 m/s
c. 4.0 m/s
d. 7 m/s

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
