9507456 Kormanik Sharks provide models, not only for studying the metabolic handling of waste nitrogen, but also the means by which nitrogen is provided for developing embryos. Uterine tissue will examined for potential carrier enzymes associated with the transfer of ammonia. Acid secretion associated with detoxification of this ammonia will be examined. Ammonia nitrogen incorporation into the embryo will also be measured. Undergraduates will be engaged and trained in all steps of the investigation. Information gained will be useful to those studying evolution of nitrogen metabolism, modelling nitrogen waste processing in fish and other animals as well as of practical use to those involved in the study of ammonia toxicity in mariculture of fish and other aquatic organisms. ***

小行星9507456 鲨鱼提供了模型，不仅用于研究废氮的代谢处理，而且还用于研究胚胎发育所需的氮。 检查子宫组织中与氨转移相关的潜在载体酶。 将检查与氨解毒相关的酸分泌。 还将测量氨氮掺入胚胎中。 本科生将参与调查的所有步骤并接受培训。 所获得的信息将有助于那些研究氮代谢的演变，模拟鱼类和其他动物中的氮废物处理过程的人，并对那些参与研究鱼类和其他水生生物的海水养殖中的氨毒性的人有实际用途。 ***
