What is difference between water potential and osmotic potential?
What is difference between water potential and osmotic potential? Solute potential (Ψs), also called osmotic potential, is negative in a plant cell and zero in distilled water. Because of this difference in water potential, water will move from the soil into a plant’s root cells via the process of osmosis. This is why solute potential […]
How is rock dated?
How is rock dated? To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed.

What results when two atoms share electrons?
What results when two atoms share electrons? A covalent bond results when two atoms share electrons. In the case of two hydrogen atoms, each shares its single electron with the other. This sharing allows each to fill its electron shell with two electrons. The pair of shared electrons constitutes a covalent single bond. How many […]
