Question 1In the life cycle of flukes:The primary sporocysts are free-swimming that develop sexually to become rediae.O The egg of a digenetic trematode hatches into an acanthor larva, which penetrates a crustacean intermediate host.O The cercaria is a free-swimming stage, and is referred to as furcocercous if it has a forked tail.The rediae are relatively more differentiated than the primary sporocysts and can develop into cercaria that infect snails. Question 3Which of the following statements is true for tapeworms Echinococcus granulosus and multilocularis?O E granulosus forms hydatid cysts, while E. multilocularis forms alveolar cysts in intermediate hosts.O E. granulosus has an acanthor larva in the life cycle, whereas E. multilocularis has a cysticeroid larvae.O Both E. granulosus and E. multilocularis have a coracidium larva in the life cycle that must be eaten by a copepod.Both E. granulosus and E. multilocularis use the flea, Ctenocephalides, and the first intermediate hosts.

Part B. Please turn in typewritten answers to the following questions 1. Asexual reproduction in diatoms occurs when the two valves move slightly apart and the cell divides in a plane parallel to the valves. A new valve is formed which nests within the parent valve. What happens to the average cell size in a population of diatoms reproducing in this manner? How has diatom life history evolved to resolve this issue of changing cell size? Explain. 2. Many benthic invertebrates produce planktonic larvae. Please provide a rationale for a meroplanktonic lifestyle. That is, what are the putative advantages of spending only part of the life cycle in the plankton? 3. Many species of zooplankton will undergo daily vertical migrations, spending the daylight hours lower in the water column and the evening hours closer to the surface. Please speculate as to why so many species display this common behavior.
