Part II:  Short Answer  Respond to each of the following completely.

1. List three characteristics of protists.

2. In what three ways can bacteria be helpful?

3. a)  Describe how amoeba feed.

How does an amoeba keep from swelling up?

An ocean sponge is placed in a fresh water pond.  
    What will happen to this organism and why? 

4.  Describe the action of a bacteriophage.

5. How is the euglena an example of symbiosis?

Part III - Answer each of the following using a properly labelled diagram:
              - Label five structures for each organism.

1.  Draw and properly label a bacterium.

2.   Draw and properly label a euglena.

3.  a)   Draw and properly label a paramecium.

     b)  How does a paramecium reproduce?

Part IV:  Graphing.   Plot the following data and answer these questions.

1. A cosmetic company runs its own lab to carry out research specifically on its products.

 A recent experiment was done to see whether using mascara (a cosmetic applied to the eyelashes) would increase the incidence of eye infections.

A sterile swab was smeared across the eyelid and then placed in the mascara.

The bacteria populations were sampled every day for one week and the following results obtained:	


	1	2000
	2	6000
	3	10000
	4	32000
	5	40000
	6	20000
	7	12000

a)  Using the data from the table above, draw a graph to show the growth of the bacteria. Plot the days on the horizontal axis and the numbers on vertical axis.

b)  Examine your graph carefully. Generally describe the growth pattern of the bacteria. Give reasons for your answer.

c)  Based on the results shown, what can you conclude from this experiment? 
     Give reasons for your answer.
