Experimental Planaria #1 Cut in half inte front (anterior) and rear (posterior) Day t 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. (Aways replace the water right away, you can use the dish lid to transfer water to and from the pianaran environment.) A. Record the length of the front (anterior) section jusAFTED you cut. This is your INITIAL front length: 5m 6) B. Record the length of the rear (posterior) section just AF TERGU cut. This is your INITIAL rear length: mro 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 daL. a) Are the cut fragments showing signs of regeneration? b) How did you identify the regenerating portion? What color…

Summoning Moaquitoes Parasites sometimes alter their hosts behavior in a way that increase their chances of transmission to another host. Dr. Jacob Koella and his associates hypothesized that Plasmodium might benefit by making its human host more attractive to hungry mosquitoes when gametocytes are available in the hosts blood. Gametocytes taken up by the mosquito will mature into gametes and mate inside its gut. To test their hypothesis, the researchers recorded the response or mosquitoes to the odor or Plasmodium-infected children and uninfected children over the course of 12 trials on 12 separate days. FIRGURE 21.18 shows their results. FIGURE 21.18 Attracting mosquitoes. The graph shows that the number of mosquitoes (out 100) attracted to uninfected children, children harboring the aseoual stage of Plasmodium, and children with gametocytes in their blood. The bars show the average number of mosquitoes attracted to that category of child over the course of 12 separate trials. On average, which group of children was most attractive to mosquitoes?
