Question 1

CLEP-Science-and-Mathematics-page205-image49

Given two solutions ZnSO4(1M) and CuSO4(1M) in an electrochemical cell, as shown above, answer

question.

Given the following standard reduction potentials, what is the standard emf of the electrochemical cell at 25°

Cu2+ + 2e− → Cu E0 = 0.34 V

Zn2+ + 2e− → Zn E0 = −0.76 V

A : +1.1 V

B : +0.42 V

C : −0.42 V

D : −l.l V

E : None of the above

Answer: A

Question 2

Guard cells are kidney-shaped cells surrounding the stomata on the underside of leaves. These cells

change their shape according to the amount of water that exists within them. The more water within, the

more swollen the guard cells are and the stomata open. When water is sparse the guard cells shrivel and

close the stomata. Recent evidence suggests that there are blue-light receptors on the plasma membrane

surface of guard cells that are coupled to potassium (K+) ion channels. K+ ions are normally found in high

concentration outside guard cell membranes when the channels are closed.

What mechanism may account for the fact that guard cells are usually open during the day and closed at

night?

A : Photosynthesis uses K+ ions; therefore, lower concentrations of potassium within the leaf drive themovement of K+ into the leaf through the guard cells.

B : The presence of sunlight drives K+ into guard cells, while driving water out of the guard cells andopening the stomata.

C : There is more water in the air during daylight hours than during nighttime hours.

D : K+ ions enter the cell through active transport only when enough water is present.

E : The presence of sunlight opens the K+ ion channels, driving potassium inside, and causing water tofollow by osmosis, swelling the guard cells.

Answer: A

Question 3
