A biologist is observing an organism under a microscope and concludes that it is a unicellular
organism.
Which of the following observations provides the best evidence that this organism must be unicellular,
not multicellular?

a. It can make its own food.

b. It can move on its own.

c. It cannot be seen without a microscope.

A student is making a model of the cardiovascular system, showing the different components, or levels, that make up this system.

Which component of the system is indicated by the question mark (?) in the model?

blood cells

heart cells

respiratory cells 

cells of other organs 

The image above shows how a plant uses light energy to make food. Choose the statment that best describes the chemical process of photosynthesis.

Carbon dioxide and oxygen are changed into glucose and water.

Carbon dioxide and water are changed into glucose and oxygen. 

Glucose and oxygen are changed into water and carbon dioxide. 

Oxygen and water are changed into carbon dioxide and glucose. 

A person's senses rely on sensory receptors. These are specialized cells in the nerves that respond to mechanical, physical or chemical stimuli. Sometimes, multiple stimuli are needed for the sensory receptors to work. All of this sensory information is transmitted to the brain.

Which of the following is most likely a chemical sensory stimuli?

odor molecules in the air

change in the body position (balance)

pressure from external objects

sound waves passing through the air

Harry examines a drop of pond water under a microscope. He draws pictures of structures
that he observes, counts them, and measures their sizes. Eight hours later, he comes back
and observes the same drop again. He counts the structures and measures their sizes.

Once again, your teacher puts ice cubes in a beaker and sets it on a hot plate. This time, the class records the temperature of the contents of the container at various points during the melting
and boiling processes.

The melting point of water is 0°C, and the boiling point of water is 100°C. Explain why the
temperature increases in Segments A and C but not in Segments B and D. Use concepts relating
to thermal energy in your answer.

Your teacher demonstrates one more way in which molecules behave when they are heated.
She carefully warms a sealed plastic water bottle using a hand warmer. As the bottle of water
gets warmer, the container changes. Select the best explanation of what happens as thermal
energy increases.

a. Heat takes up space and causes the bottle to expand.

b. The molecules move faster and closer together, which causes the bottle to collapse.

c. The molecules move slower and closer together, which causes the bottle to collapse.

d. The molecules move faster and farther apart, which causes the bottle to expand.
