Base your answers to questions 16 through 18 on the information below and on your
knowledge of biology.
An experiment was carried out to answer the question “Does the pH of water affect the growth
of radish plants?” Two groups of ten radish plants were set up. One group was watered with
water having a pH of 3.0, and the other group was watered with water having a pH of 7.0. Both
groups of plants received the same amount and intensity of light, the same amount of water,
and they were grown in the same type of soil. The heights of the radish plants were measured
every 2 days for a period of 2 weeks.
16._______Which sentence is a possible hypothesis that was tested in this experiment?
1.
2.
3.

Does the pH of water affect the growth of radish plants?
Will the amount of water alter the heights of the radish plants?
The temperature of the water will affect the heights of the radish plants.
The pH of the water will affect the heights of the radish plants.
17.__________What was the dependent variable in this experiment?
(1) heights of the plants (3) temperature of the water
(2) pH of the water
(4) type of soil
18__________Which activity might help to increase the validity of this experiment?

Base your answers to questions on the passage below and on your knowledge of biology.
Blown Away Head Lice Meet Hair Dryer of Death
Head lice are becoming indestructible. A study found that as many as 80 percent of the bugs
are [resistant] to insecticides in over-the-counter shampoos, and resistance will only increase.
Evolutionary biologist Dale Clayton may have a new line of attack. Clayton, who usually studies
lice on bird feathers, stumbled onto his solution after a major research setback. When he
moved his laboratory from England to the University of Utah a decade ago, his entire louse
collection perished in the dry desert air. Soon after, his 8-year-old came home from school with
head lice. He wondered if human head lice could also be killed by drying them out. “It was sort
of a forehead slapper,” Clayton says. After conventional hair dryers failed, Clayton came up
with the LouseBuster, a 10-pound device resembling a vacuum cleaner that desiccates [dries
out] the bugs with a jet of 140-degree air [140°F]. “It’s a pretty brutal assault,” he says. Tests
show the invention is both safe and effective, eradicating 80 percent of live lice and 98 percent
of eggs, leaving survivors unable to breed. And, Clayton says, “it will be awfully hard for lice to
develop resistance.”

• state one way the control group will be treated differently from the experimental group [1]
• state one result of the experiment that would support the hypothesis [1]
