What about REDOX potential and its role in water stability in closed systems?
or the role and pathway of Carbon in the Kreps Cycle?
or main types of Autotroph organisms based on the nature of primary source of energy?
or boundaries between algae and bacteria and fungi?
or explore how symbiotic relationships among distinct microorganisms made possible photosynthesis in plants?
or the physiology of the swim bladder in Polypterus sp as a quasi-primitive lung?
or the life cycle of most common pathogens in freshwater aquaria?
or the life span of Microphis brachiurus lineatus in Nature?
There are so many interesting topics in General Biology that all I can say is keep your research at descriptive/exploratory level, this is College not Graduate School. Some topics we have little idea about even very simple questions, like the life span of Microphis brachyurus lineatus in Nature. Writing about it and coming to the conclusion that further research is needed is a common place in research papers, just make sure you made a good effort in searching through literature.
