Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.

As the Earth rotates, your region of Earth passes through both of these bulges each day. <u>When you're in one of the bulges, you experience a high tide. When you're not in one of the bulges, you experience a low tide.</u> This cycle of two high tides and two low tides occurs most days on most of the coastlines of the world.
The specific magnetism of basalt rock is determined by the Earth's magnetic field when the magma is cooling. Scientists determined that the same process formed the perfectly symmetrical stripes on both side of a mid-ocean ridge. ... Oceanic crust slowly moves away from mid-ocean ridges and sites of seafloor spreading.
