First Semester Final - Biology

1) Maya, Mason, and Scarlett are budding scientists. They know that their work usually begins with

• testing a hypothesis

• careful observations

• creating experiments

• drawing conclusions

Mason and Arjun were working on their science project. They observed a sunflower plant in their backyard grow 3 cm over a two-week period. This information they gathered is called

• inferences

• variables

• hypothesis

• data

3) Jackson, Hannah, and Elijah were observing the growth of mold on bread in their science project. They noticed that the bread mold seemed to grow faster when they sprinkled water on it. Based on their observations, they suggest that the presence of water could accelerate the growth of bread mold. This is

• a conclusion

• a hypothsis

• an experiment

• an analysis

4) During a science experiment in class, Noah isolates and tests

• a conclusion he made about the experiment

• a mass of information he gathered from his textbook

• a control group consisting of Maya and Harper

• a single variable in the experiment

Emma, Samuel, and Ethan are observing different organisms in their biology class. They noticed that all organisms share certain characteristics. However, Samuel pointed out one characteristic that is NOT shared by all living things. Which characteristic did Samuel point out?

• growth and development

• ability to move

• response to the environment

• ability to reproduce

Liam, Mason, and Arjun noticed that some birds in their North American neighborhood fly south every winter. Which of the following characteristics of these birds best explains this behavior?

• These birds respond to their environment.

• These birds maintain internal balance.

• These birds are made up of units called cells.

• These birds are based on a universal genetic code.

Aiden, Anika, and Mia observed a plant in their school garden. According to their observations, which characteristic of the plant illustrates a characteristic of living things as shown in Figure 1-1?

• The plant grows and develops.

• The plant is made up of cells.

• The plant needs material and energy.

• The plant reproduces.

Aria, Priya, and Elijah are studying biology. They learned about a process by which organisms keep everything inside their bodies within certain limits to maintain a stable internal environment. What is this process called?

• homeostasis

• evolution

• metabolism

• photosynthesis

Michael, Avery, and Ethan are planning a road trip. They are discussing whether to use the standard English system of measurement (yards, miles, quarts, gallons) or the metric system (meters, kilometers, liters) for their trip. Why would the metric system be simpler for them to use?

• Metric units are easier for Michael, Avery, and Ethan to measure than English units.

• The metric system is based on multiples of 10.

• The metric system is used by everyone in the world.

• Metric units are smaller than English units.

10) Aiden, Anika, and Evelyn are conducting a science experiment for their school project. They realize that using a universal system of measurement is most crucial during which part of their scientific methodology?

• when they are asking a question

• when they are forming a hypothesis

• when they are collecting data

• when they are drawing conclusions
