✂ answer key — fold or cut before handing out

1-A 2-B 3-B 4-B | 5 = 1:1 6 = neutrons 7 = stomata 8 = cohesion-tension theory (transpiration pull) 9 = a weak acid and its conjugate base (or a weak base and its conjugate acid) | 10 = Velocity and acceleration are different quantities — velocity describes how fast position is changing, while acceleration describes how fast velocity is changing. Gravity acts on the ball continuously throughout its entire flight, pulling it downward at a constant g, regardless of whether the ball is moving up, momentarily stationary at the peak, or moving down — so acceleration stays at g the whole time even during the single instant when velocity passes through zero.
