2 hydrogen atom with 1 valence electron each (answer B) will react forming a covalent bond.
covalent bond is a chemical bond that come by sharing of one or more electron pair between two atoms. when two hydrogen atoms react, they form a covalent bond by sharing electrons among themselves.
Answer:
Adding a concentrated salt solution to the solution containing cheek cells will cause the water to move outside the cells by osmosis. The cheek cells are at a higher water potential than the outside solution so, the water will move out, down the water potential gradient, until an equilibrium is reached.
Hope that answers the question, have a great day!

Answer:
Acid-base indicators are generally weak proteolytic that change color in solution according to the pH. The acid-base equilibrium of a weak acid type of indicator (HI) in water can be represented as. [I] The acid, HI, and the conjugate base, I−, have different colors. The equilibrium expression for this process is.
