Answer: A solution that is a 4 on the pH scale is a (a) weak acid.

The pH scale is a universal measure of how much acidic or basic any substance is. The scale of pH ranges from 0 to 14 with 7 in middle being neutral i.e. neither acidic nor basic. Substances with pH less than 7 are considered to be acidic and more than 7 are considered to be basic. Strong acids have pH less than weak acid while strong bases have higher pH than weak bases.

Substances or solutions that have pH 0-3 are highly acidic, 4-6 are weakly acidic and pH of 7 is neutral solution while pH of 8-11 are weakly basic and 12-14 are highly basic.

facilitated diffusion requires _____. a. membrane proteins b. transport proteins c. membrane pouch d. energy
Goryan [66]
The answer is <span>b. transport proteins.
</span>
Facilitated diffusion is the process of passive transport, which means without using of energy, of ions and molecules across a cell membrane. Although, this process does not require energy such as active transport, transport proteins are required. The role of transport proteins in facilitated diffusion is to provide a hydrophilic route within hydrophobic lipids of the membrane, and that way facilitate ions and molecules to cross the membrane.
