Tree Leaves That Reduce Transpiration
Small leaves
Needlelike leaves, such as on conifers
Leaves with hairlike structures
Leaves with waxy coverings
Which of these is most likely observed in an area experiencing a
long-term drought?
F Trees with broad leaves will be more healthy than trees with
needlelike leaves.
G Trees with leaves that have waxy coverings will be more healthy
than trees without wax-covered leaves.
H Trees with broad leaves will be more healthy than trees with
small, flat leaves.
J Trees with leaves without any hairlike structures will be more
healthy than trees with leaves covered by hairlike structures.

38 When a coin is tossed in the air, it travels upward, gradually slows
down, momentarily reaches zero speed, then moves back
downward with increasing speed. Which statement best explains
this change in the coin’s motion?
F The force of gravity causes the coin to change its velocity.
G The coin’s inertia decreases on the way up and increases on the
way down.
H The action-reaction force pair of gravity and the applied force
cancel each other.
J The coin remains in its state of upward motion until the force of
friction acts upon it.

40 Students performed a lab investigation on chemical reactions. The
students put on goggles and plastic gloves and then followed these
steps.
1. Pour 150 milliliters of vinegar into a beaker.
2. Place a thermometer in the vinegar and record
measurements.
3. Add a piece of steel wool to the beaker.
4. Observe and record thermometer
measurements.
5. Remove the steel wool from the beaker.
6. Use tweezers to pull strands of the steel wool
apart and observe changes.
Which observation would indicate that a chemical reaction
occurred?
F The vinegar took the shape of the container in step 1.
G The steel wool sank into the vinegar in step 3.
H The temperature of the vinegar increased during step 4.
J The steel wool changed shape during step 6.
