pict Experimental Planaria #1 Cut in half into front (anterior) and rear (posterior) Day 1 Measuring the Planaria This operation is best performed by removing some of the water from the dish into the lid with a clean pipette and waiting for the worm to stretch out. Measure the length of the worm in millimeters. (Always replace the water right away, you can use the dish lid to transfer water to and from the planarian environment.) A. Record the length of the front (anterior) section just AFTER you cut. This is your INITIAL front length: 5 m m B. Record the length of the rear (posterior) section just AFTER you cut. This is your INITIAL rear length: 3mm C. Observe and record any behavioral responses just after your cut Day 2 Spend time under the microscope observing the cut Planaria. Answer the following questions based on your observations. NO measurements will be taken on this day. a) Are the cut fragments showing signs of regeneration? b) How did you identify the regenerating portion?…

Encode the word true if the statement is correct. If the underline word/s is incorrect, then correct the underlined word/s that makes the statement wrong by encoding the correct answer beside false. Answers must be encoded in capital letters 1. When Grammia incorrupta caterpillars are infected by a parasitoid, they show an increased preference for acidic toxins found in larval food plants, and by choosing to eat these toxic plants when infected, are able to increase survival.

Liver Flukes Procedure View the preserved liver fluke specimens. Liver flukes are an example of a parasitic flatworm. Also, access this website to learn more about the liver fluke life cycle: http://www.cdc.gov/parasites/fasciola/biology.html 1. Where does the adult liver fluke live? 2. When the liver fluke egg hatches, what organism does it infect first? 3. Can humans become infected? View the preserved tapeworm and the slides of the tapeworm scolex (head) and proglottids (reproductive bodies). This is another example of a parasitic flatworm. Also, access this website to learn more about the tapeworm life cycle: http://www.cdc.gov/parasites/taeniasis/biology.html 1. What structures are located on the scolex to help the tapeworm attach to the host? 2. Are tapeworms hermaphrodites? 3. Name two livestock that can be infected by tapeworms. 4. If a human is infected, where does the tapeworm live?

N. fowleri usually completes its entire life cycle by eating bacteria (e.g., in pond water). What is an appropriate term for its relationship with humans?
