3. This is information collected during a scientific investigation.

4. This is a statement an experiment is designed to test.

5. An if… then… statement that is used to test a hypothesis.

6. This is the sample or group of samples that does not receive any of the independent variable.

7. In an experiment to find the effect of X on Y, this variable is the dependent variable.

8. This is a pure substance which can be broken down into simpler substances.

9. In this type of bond, pairs of electrons are shared between atoms

10. This type of bond is illustrated by the dashed line.

11. The primary function of this group of macromolecules is to store energy.

12. These are the chemical monomers enzymes are made of.

13. This cell part is responsible for capturing light energy in plants.

14. This organelle is where ATP is produced during aerobic respiration.

15. This important cell part controls the activity of a cell and stores genetic information.

16. This cell structure is a phospholipid bilayer with proteins floating in it. DAILY DOUBLE

17. This type of cell is small, simple, and doesn’t have a nucleus.

18. This term describes a solution where there is an equal concentration of solute throughout the mixture.

19. This type of transport does not require any energy to be used by a cell, since molecules are moving from areas of high to low concentration.

20. If placed in very salty water, a cell will lose mass because of this process.

21. A solution which contains a lower solute concentration than the cells in it is said to be this.

22. This type of membrane allows some things to pass through, but not others

23. These are the three inputs to the process of photosynthesis.

24. Cellular respiration produces these 3 end products.

25. These two inputs to photosynthesis are outputs of aerobic respiration

26. This type of respiration has only one energy-producing step: glycolysis.

27. This chemical can be “recharged” by adding a high-energy phosphate group to it.
