able to identify and list the function of the compound light microscope
If the sample is too thick on a microscope slide, what will we see? - Answer-Too thick to
see cells?
What are the six steps of the scientific method? - Answer-Observation, Form a
Question, Hypothesis, Conduct Experiment, Analyze Data, Draw Conclusion
What is the difference between a hypothesis and a prediction? - Answer-Hypothesis is a
testable, informed guess
What is meant by a null hypothesis? - Answer-Hypothesis that proposes no statistical
significance occurs
Independent variable - Answer-A variable whose variation does not depend on that of
another

What type of organism is Lichen? - Answer-Simple, slow-growing plant
What type of cells are snakes blood? - Answer-Draw snakes blood
Be able to identify an Erlymeyer flask, beaker, graduated cylinder, volumetric cylinder -
Answer-Which is the most accurate for liquid measurement? How can you tell?

chromosomes
Are strawberry cells eukaryotic or prokaryotic? - Answer-Eukaryotic
Are cheek cells eukaryotic or prokaryotic? - Answer-Eukaryotic
List two types of cellular replication - Answer-Mitosis and meiosis
Why do our cells undergo mitosis? - Answer-Growth, development (acquiring new traits
with age), and repairing injured cells
Which cells undergo mitosis? - Answer-Somatic
Chromosome - Answer-Long, thin strings composed of DNA and proteins which carry
genes
Chromatid - Answer-Associated DNA and histones
