Answer:

Simple Diffusion.

Explanation:

The plasma membrane is known as the selectively permeable membrane as they allow the movements of some selected particles only. The movement are facilitated diffusion, active transport and passive transport.

Water molecules are polar in nature. They can pass through the plasma membrane from its region of the higher concentration towards its region of the lower concentration. They move directly through the simple diffusion and does not require any protein or energy molecule to pass through them.

The use of which material can substitute for copper and reduce copper mine production?
Lesechka [4]

Answer:

Glass

Explanation:

Copper is a good conductor of electricity and this is why it is used in electrical equipment to transmit electrons with the least resistance. Cable conductors are made of copper and used to transmit data. Copper is now being replaced by optic fiber that is made of glass. Instead of using electrons, fiber optic transmits data using photons – which transmits more data rate than copper.
