$400 Introducing bias Several students are conducting an experiment to test the effect of exercise on heart rate. The students decide to ignore any results that were too far above or below their prediction. They repeat these trials until a value closer to their prediction is obtained.

$600 Which soap is most effective in killing bacteria? A student washes her hands with antibacterial soap and water. Then she touches the agar in a petri dish with her thumb. The agar contains nutrients that support the growth of bacteria. Other students repeat the procedure after washing their hands with three different kinds of antibacterial soap. The petri dishes are kept warm overnight to allow bacteria to grow. The next day the students count the number of bacterial colonies in each dish. What question were the scientists trying to answer?
$800 the movement of the submarine Scientists are developing a microscopic submarine to deliver medicine to sites within the body. A biomotor that uses bacteria would move the submarine.

$1000 the effectiveness of the fertilizer used on the plants A group of students conducted an experiment to study the growth of bean plants. They used two pots labeled “A” and “B.” Each pot contained 20 small bean plants of similar height. All the plants were treated alike except for the solution they received. Each day for five days, the plants in Pot A were given 40 milliliters of distilled water, while the plants in Pot B were given 40 milliliters of distilled water containing one gram of fertilizer. The table below shows the average height of the plants in each pot for each day of the experiment. What is being tested in this experiment?

Scientists wanted to study the effect of water temperature on the swimming speed of goldfish. They set up an experiment in which they raised populations of goldfish in two different aquariums. Population 1 was raised at 5°C. Population 2 was raised at 25°C. All other variables were constant in both aquariums. The results of this experiment are shown in the graph below. • According to the graph, both populations of goldfish swim at the same speed at which of these temperatures? $600 ~17
$800 Heart rate • Several students are conducting an experiment to test the effect of exercise on heart rate. Students do 20 sit-ups in one minute of exercise. The data chart below shows the heart rate at one-minute intervals for each student. • What is the dependent variable?

$400 meiosis The largest flower in the world, called a rafflesia, is three feet wide and weighs up to 36 pounds. The rafflesia has no roots, stems, or leaves. It lives on and takes nourishment from a vine called tetrastigma. The rafflesia harms the vine. The seeds of the rafflesia are dispersed in an unusual way. Plantain squirrels and tree shrews eat parts of the rafflesia plant. Scientists observe that when the animals chew the rafflesia, seeds get caught in their teeth. The animals will then chew on tetrastigma vines, leaving the seeds where they can germinate. Specialized cells in the rafflesia flowers undergo a process that produces gametes. What is this process called?
