Alex tested three brands of batteries to learn which would last the longest in a flashlight. He placed two brand "A" batteries in a flashlight, turned the flashlight on and measured the time that the light shined. He repeated the experiment with battery brands "B" and "C" using the same flashlight. He recorded the data on the bar graph above. Which of these is an accurate conclusion that Alex can make about the batteries he tested?

Jeremy conducted an experiment that compared the effects of difference sounds on the growth of bean plants. He planted bean seeds of the same type and size in three containers using the same type of soil in each container. He placed the containers in the locations shown above. Jeremy gave each plant the same amount of water at the same time each day. After two weeks, Jeremy observed that the plant in the living room was the largest and had the most leaves. Jeremy concluded that the bean plants grow the fastest when exposed to television sounds. Which is the greatest error that Jeremy made in his experimental design?

After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scorpion species that lived 255 million to 460 million years ago, was 2.5 meters long. Which of the following conclusions is supported by this information?

The Texas blind salamander (Eurycea rathbuni) lives in the Edwards Aquifer region around San Marcos. Along with other species the salamander lives in total darkness in the underground crevices and caves of the aquifer region. The table above lists some of the organisms that live in this environment and their food sources. In an energy pyramid for these aquifer cave dwellers, which of the following would be placed at the bottom?

A harmless scarlet king snake and a venomous eastern coral snake have similar band patterns as shown in the photograph above. For the scarlet king snake, the adaptation of having a banding pattern like the eastern coral snake's is known as mimicry. The outcome of this adaptation in the scarlet king snake is to
