The diagram below shows cells in a beaker. Salt cannot move in or out of 5 points the cell, but water can. In which direction would water move if the cell has
30% salt and the water solution has 90% salt? *
water would move into the cell
water would move out of the cell
water would not move
would move pnually into and out of the cell

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
