Unit 1 Scientific Method, Living Things, Cells

What do we call the If, Then Statement in an Experiment?

• Conclusion

• Hypothesis

• Independent Variable

• Dependent Variable

What type of variable are the things we keep the same in an experiment?

• Number Variable

• Independent Variable

• Dependent Variable

• Constant Variable

In an experiment we change is called this type of variable.

• Number variable

• Independent variable

• Dependent Variable

• Constant Variable

Where do we write down and organize our results from an experiment?

• Data Table

• Line Graph

• Bar Graph

• Conclusion

One characteristic of all living things is that they

• develop organ systems

• produce identical offspring

• maintain internal stability

• synthesize only organic matter

In a cell, protein synthesis is the primary function of

• ribosomes

• mitochondria

• chloroplasts

• vacuoles

Specialized internal structures used by cells to maintain homeostasis are called

• tissues

• systems

• organs

• organelles

Energy can be stored in ATP because of the process of

• digestion

• cellular reproduction

• cellular respiration

• diffusion

How are single celled organisms able to function without organs?

• organs are not needed for homeostasis

• multicellular organisms do not have organelles

• unicellular organisms cannot function without organs

• organelles act in a similar way to organs

The cell membrane

• helps with the removal of wastes in plant and animal cells

• cell communication in animal cells only

• the outer barrier in plant cells

• does not allow gas exchange in plant or animal cells
