Multiple Choice

A research group has discovered that damselflies, a type of dragonfly, are being infected by a particular type of aquatic protozoan. Both young and adult damselflies are not directly infected by the protozoan but contract the infection from the prey they eat. The graph shows the percentage of adult damselflies infected by protozoans during the summer and early fall. Which of the following conclusions is supported by the graph?

• Infection in embanked ponds increased during the sampling period.

• Protozoans were more common in creek-fed ponds than embanked ponds.

• Protozoans reproduce more quickly in embanked ponds than creek-fed ponds.

• Infection in creed-fed ponds remained constant throughout the sampling period.

Multiple Choice

The disease polio once sickened thousands of children every year. The graph depicts the number of polio cases that occurred between 1952 and 1973, based on information from the U.S. Department of Health, Education, and Welfare and the Centers for Disease Control. The data best support which of these statements?

• Introducing a vaccine for polio had no effect on the number of cases of polio diagnosed each year.

• The polio vaccine was effective in protecting thousands of people from this disease.

• The vaccine proved ineffective because cases of polio rose between 1957 and 1959.

• The sources of the data are not reliable and, therefore, the data should be ignored.

Multiple Choice

Indira tested whether a tomato plant grew faster in part shade or full sun. The table below shows the height of each plant after 0, 10, 20, and 30 days. What is one conclusion Indira can draw from her data?

• All plants grow taller in full sun than they do in part shade.

• Tomato plants need to be placed in full sun in order to grow.

• Tomato plants grown in full sun will produce more tomatoes.

• The tomato plants grew taller in full sun than they did in part shade.

Multiple Choice

Antibiotics prevent the growth of bacteria. Bacteria have adapted, becoming resistant to antibiotics and making antibiotics ineffective in fighting an infection. After reviewing the graph, choose which of the following would be a reasonable inference.

• Between 2001 and the present time, bacteria’s resistance will have dropped to 10%.

• Between 2001 and the present time, bacteria’s resistance will have increased to 31%.

• Between 2001 and the present time, bacteria’s resistance will be at the same percentage.

• After 2001, bacteria’s resistance to antibiotics will begin to drop until it reaches 0%.

Multiple Choice

An experiment was designed to study the effects of salt concentration on the mass of potato tissue. Six pieces of potato of equal mass were placed in six different concentrations of salt water for the same amount of time. The mass was then measured, and changes were recorded on the graph.

The graph shows that potato tissue gets heavier

• As the salt concentration increases.

• As the salt concentration decreases.

• The longer it is left in the salt solution.

• Because it loses water to the salt solution.
