Honors Biology Final Practice

1) Aria, David, and William are budding scientists. Their work usually begins with

• testing a hypothesis

• careful observations

• creating experiments

• drawing conclusions

Aria and Rohan were working on their science project. They observed a sunflower plant in their backyard grow 3 cm over a two-week period. What is this information called?

• inferences

• variables

• hypothesis

• data

3) Benjamin observed that his bread was molding faster than usual. He suggested that the presence of water could accelerate the growth of bread mold. This suggestion is

• a conclusion

• a hypothesis

• an experiment

• an analysis

Emma, Ethan, and Abigail are conducting a science experiment in their school. During this controlled experiment, what is the one thing that a scientist like Ethan isolates and tests?

• a conclusion

• a mass of information

• a control group

• a single variable

Anika, Scarlett, and Olivia are discussing scientific theories in their science class. Anika says that a theory

• is always true.

• is the opening statement of an experiment.

• may be revised or replaced.

• is a problem to be solved.

Mason, Nora, and Abigail are in a science class. Their teacher explains that a well-tested explanation that explains a lot of observations is

• a hypothesis

• an inference

• a theory

• a controlled experiment

7) In a class discussion, Mia prefers to always sit on the left side of the room. This is an example of

• a bias

• a theory

• a hypothesis

• an inference

Elijah, Emma, and Jackson are observing different organisms in their biology class. They noticed that all organisms share certain characteristics. Which of the following characteristics observed by Emma is NOT a characteristic of all living things?

• growth and development

• ability to move

• response to the environment

• ability to reproduce

Mia, Nora, and Evelyn noticed that birds in their North American town fly south every winter. Which of the following characteristics of living things best explains this phenomenon?

• Living things respond to their environment.

• Living things maintain internal balance.

• Living things are made up of units called cells.

• Living things are based on a universal genetic code.

10) Henry, Anika, and Nora are observing different cells under a microscope in their biology class. They notice that cells in multicellular organisms like humans, plants, etc., have many different sizes and shapes. These differences are called cell specialization. Henry asks, 'What does cell specialization allow cells to do?'

• reproduce

• perform different functions

• respond to their environment

• be less complex
