(12 pts) Cells Short Answer Section: The figure below represents an animal cell OR a plant cell OR a bacterial cell (exactly one of these!).  You need to know which one it is to answer all of the questions correctly.  Right answers for the wrong cell type won’t count.  ALL the matching questions should be answered with this same cell type in mind. Match the letters labeling components in the cell diagram, and boxes in the concept map below the cell diagram, to the appropriate answer choice.

1B. (3 pts) Briefly describe an experiment that you could do to test your hypothesis.

Penguins and dolphins both have flippers that they use for swimming in the ocean.  This is an example of. . .

4. Evolution is only a theory; there is little evidence to support it.

Evaluating Evolution Statements There are six statements about evolution written below.  Evaluate whether these statements are true or false.  If they are true, write ‘true’.  If they are false, explain why.

Light Waves? In class you were asked to observe an unusual biological phenomenon (e.g. a black lemur self-anointing with a millipede) and then hypothesize what you thought could be happening.  Time to do that again, only this time with the phenomenon of bioluminescent waves.   In some parts of the ocean humans can see a mysterious glow.  This glow is usually intensified by movement; swimming, surfing, or boating through it makes the glow more intense.  Scientists have discovered that the glow is caused by dinoflagellates living in the water. Dinoflagellates float near the surface of the sea where they make a living via photosynthesis and the ingestion of other types of phytoplankton; dinoflagellates in turn get eaten by copepods, small marine crustaceans. Dinoflagellates have special structures called scintillons inside their vacuoles that generate this light using an enzyme called luciferase.  Generating this eerie blue-green light costs energy and resources. Interestingly, they only generate this light at night and only in response to motion.
