Which statement best represents how structure relates to function?
A horse's mane is often black.
Many tropical birds can be taught to speak.
Great white sharks have sharp serrated teeth for tearing into their prey.
Some insects live longer than others.
How does eye location best represent the relationship between structure and function?
It indicates the maximum height an organism can reach.
It determines how much of the surroundings an organism can see.
It affects how an organism interacts with others in its population.
It determines how an organism responds to changes in the length of the day.
READ THE SCENARIO:
Hemlocks are a common type of tree in the northern forests of the United States. In studying one forest, a forester noticed that mature hemlocks were abundant but there were very few young hemlocks. She wondered why there were so few young hemlocks.
By reading the records that other foresters in that area had kept, she learned that the population of deer living in the forest had doubled in the last five years. By reading studies on forests that other scientists had performed, she also learned that deer in similar forests like to eat young hemlocks and the young trees of other species.
Which question most closely relates to the forester's observations and the collected scientific data on forests?
Did a lack of rain cause the hemlocks to stop reproducing?
Are deer eating most of the young hemlocks?
Why are there so many deer in the forest?
Do the young hemlocks have a disease?

In the scenario, the forester wonders why one forest had mature hemlocks and very few young hemlocks.
Which part of a scientific method does this best illustrate?
Setting up an experiment
Communicating the results of a study
Forming a hypothesis
Making an observation and asking a question

Which statement is a hypothesis that would best address the question "Are deer eating the young hemlocks and preventing them from growing?
Deer are eating young hemlocks.
If the hemlocks are tasty to the deer, the deer will eat them.
If deer are eating young hemlocks, then keeping deer away from the young trees will allow the trees to grow.
Deer will eat young hemlocks, but not old hemlocks.
READ THE SCENARIO:
A scientist sets up an experiment to see how colored lights affect the height of plant growth. He grows one group of plants in full sunlight, one group under red lights, one group under blue lights, and one group under green lights.
All the plants are exactly that same type and all receive an equal intensity (brightness) of light. At the end of the experiment he measures all the plants.
What is the dependent variable?
The intensity of the light
The color of the light
The height of the plant
Sunlight

The desert tortoise digs and hides in a burrow during the day to stay cool because of the extreme heat aboveground.
Which characteristic of life does this behavior best illustrate?
Metabolism

Cellular Organization
Which statement best illustrates how an organism maintains homeostasis?
Female barn swallows mate with long-tailed males.
Parents pass their traits to their offspring.
Desert pack rats are active at night to conserve water.
Young hawks have different kinds of feathers than adult hawks.
If the results of an experiment do not support a scientist's hypothesis, what should the scientist conclude?
She must have made a mistake or forgotten something with the experiment.
Her hypothesis was bad.
She should give up on research.
She may want to alter some aspects of the experiment and try again.
Which phrase best describes the dependent variable in an experiment?
The variable that is measured
The variable that is manipulated

What is the molecule called that stores this chemical energy?
Oxygen
Carbon Dioxide
Carbon

Which phrase best defines homeostasis?
The maintenance of an organism’s internal environment within certain limits
The ability of an organism to find its own food
The maintenance of an organism’s external environment within broad limits
The ability of an organism to find a mate
Beyond the organism, which set of groups does biological organization extend to?
Populations, Communities, and Ecosystems
Family, Genus, and Species
Cells, Tissues, and Organs
