114 A student using a compound light microscope to study plant cells 
observed that most of the cells resembled the diagram shown below.

Which diagram best illustrates how these plant cells will appear after they
are placed in a solution having a lower water concentration than the cells 
have.

Base your answers to questions 115 through 118 on the passage below 
and on your knowledge of biology.

The snowshoe hare (Lepus americanus) is the prey of many woodland animals. Foxes, 
coyotes, martens, and weasels hunt the hares by day, while the great horned and barred
owls hunt them on silent wings at night. The snowshoe hare survives this predation partly 
as a result of the effects of changing environmental conditions on the expression of genes 
for fur color, resulting in effective camouflage. In winter months, the hare has white fur, 
which blends into the snowscape. During the warmer months, the fur changes to a reddish 
brown.

Some favorite foods of the hare during the winter months are twigs of the maple, birch, and 
apple trees. Grasses and clover replace this diet during the spring and summer. Hares tend
to feed during the hours of dusk and dawn, when the light is low and the predators are 
inactive.

The hares prefer habitats along streams, wetlands, and spruce forests. Their breeding season
in New York State begins in March, and a female can have a litter of one to six young only
5 weeks after mating. The young hares are able to see, are fully  furred, and are able to 
walk and hop soon after birth. Females nurse their young until they are about a month old.
Within one season, a female may have tip to four litters. The snowshoe hare population 
tends to vary throughout the year because individual animals have a short lifespan. There 
seem to be cycles of about 10 years, during which the population varies from about 0. 1 
hare per acre up to 5 hares per acre. Some biologists suggest that the cycles are related to
predation and the depletion of the hare’s food resources.

115 If food supply is the only limiting factor, which graph best represents 
a possible relationship between the population of snowshoe hares and their 
food supply over a 10-year period?
