Answer:
Osmosis is the process that best describes the movement of water molecules into and out of the cell.
Explanation:
- Osmosis can be understood as the net shift of water molecules or its movement between the permeable membranes.
- Osmosis is caused by the difference in solute concentration between the consecutive membranes.
- Osmosis process do not transfer any ions and solutes contained by the water molecules.
- The movement of water is always from the lower concentration level to higher concentration level.
- Example of osmosis can be seen during the absorption and secretion of water in our small intestine.
Answer:
Explanation:
The formula for density is ρ
(where 
represents mass, and 
represents volume).
With this formula, we can calculate the density of the object:
ρ
