1.) describe specialized feeding structures of parasitic platyhelminths.
2.) some parasitic flatworms have a very complicated life cycle with more than one host. infer why this might be adaptive.
3.) how do free-living nematodes contribute to the carbon cycle?
4.)apply what you know about pinworms to develop one or more recommendations for preventing pinworm infections in humans.
5.) platyhelminths and nematodes are both worms. justify classifying them in different invertebrate phyla.

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
