Directions: Answer the following questions. You may utilize your notes, text or outside materials to help you.
1. What is the difference between a theory and a scientific law?
2. What is the difference between an autotroph and a heterotroph?
3. When setting up a proper experiment, a scientist must have four distinct parts to that experiment. Name
these four parts and give a definition of each part.
4. Why must an organism expend energy to maintain homeostasis?
5. If an ion has 12 protons, 14 electrons and 12 neutrons, what is the ions charge?
6. What is the difference between an ionic bond and a covalent bond?
7. Explain the difference between endergonic reactions and exergonic reactions in terms of energy of the
starting materials or reactants and ending materials or products.
8. The pH scale is a measure of the amount hydrogen ions (also called hydronium ions) in a solution. The more
hydrogen, the greater the acidity level and the lower the pH. What ion is in great concentration if the pH of a
solution is 12? Is this solution an acid or a base?
9. There are four major macromolecules or polymers every organism must possess. Name these four and give
their monomer subunit.
10. What type of macromolecule is an enzyme? A phospholipid? A wax? DNA? Glucose?

12. Why must cells limit their size?
13. What is the difference between a prokaryote and a eukaryote? Give an example of each.
14. Give the function of each of the following organelles: mitochondria, nucleus, cell membrane, ribosome,
lysosome, rough endoplasmic reticulum, smooth endoplasmic reticulum, chloroplast, and vacuole.
15. What is the difference between diffusion and osmosis?
16. If a cell is placed in a hypotonic solution, what happens to it? A hypertonic solution?
17. Name two types of endocytosis. How do these two types differ?
18. How are photosynthesis and cellular respiration related?
19. Give the products and reactants of photosynthesis.
20. Give the products and reactants of cellular respiration.
21. What is the difference between chlorophyll and carotenoids?
22. Name the three stages of cellular respiration and tell whether each step is aerobic or anaerobic. Which step
is the most efficient at producing ATP?
23. What are the similarities and differences of lactic acid fermentation and alcoholic fermentation?
