In 1796, Edward Jenner investigated the relationship between cowpox and smallpox. People who became ill with cowpox, a nonfatal disease, did not catch smallpox, a deadly disease. Jenner injected a patient with the cowpox virus and several months later injected the same patient with smallpox virus. The patient did not contract smallpox. Jenner’s research influenced the development of what?
painkillers
anesthetics
vaccines
antibiotics

Students conclude that water molecules, not sucrose molecules, moved into and out of the bag. Which statement best defends the conclusion?
The distilled water in the beakers had the least change in mass.
The change in mass indicates the movement of sucrose molecules.
Only distilled water can cross a semipermeable membrane.
Molecules only move when the sucrose concentration is above 5.00%.
The class concluded that the rate of photosynthesis increases when the plants are closer to the light source. Which statement best supports the students’ classroom conclusion when applied in a pond ecosystem?
Most aquatic plants found in a pond have small leaves.
Most aquatic plants in a pond are found in shallow waters.
Most aquatic plants found in a pond belong to the same species.
Most aquatic plants in a pond are found in areas of moving water.
The research company evaluated a two-year study on the use of asthma inhalers conducted by Agency X. Agency X had concluded that the data they collected were valid and the inhalers were effective in the treatment of certain asthmatic conditions. The research company followed the same procedure set up by Agency X. They used a double blind study with the same number of different patients, for the same time period. The research company determined that the conclusion of Agency X is valid and that the inhalers are effective. To ensure their results are free of bias, Agency X
performed a two-year study.
researched a previously published paper.
had the research company use the same patients.
sent the results to an independent research company.

is a toxin to algae.
is used by algae as a nutrient.
supports the growth of algae competitors.
prevents overgrowth of algae.
A biology class is investigating whether the amount of dissolved oxygen in an aquarium changes when water temperature changes. They set up two aquariums, one as a control and the second as the variable. They will record the dissolved oxygen content over a 3-month period using an oxygen monitor. What other tool is necessary to conduct this investigation?
pH meter
microscope
thermometer
graduated cylinder
Which statement explains why the compact fluorescent light bulb (CFL) is the best choice?
The CFL light bulb lasts longer than the incandescent light bulb.
The CFL light bulb is cheaper than the light-emitting diode light bulb (LED).
The CFL light bulb provides the longest life span for the least cost.
The CFL light bulb uses more electricity per hour than the light-emitting diode light bulb (LED).
A company has produced an absorbent polymer that helps remove oil from contaminated ecosystems. However, this polymer is expensive to produce in mass quantities. Which statement best explains how this technology is beneficial, even though it is expensive to produce?
It reduces the likelihood of oil spills.
It ensures the survival of endangered species.
It helps the environment return to a healthy state.
It produces clean drinking water for human consumption.
