Hi, I am doing my extended essay in biology(obvisly from the title). My topic is related to plant and the effects of different concentrations of vitamins on the rate of growth of Solanum lycopersicum (tomatos). I said this to my techer and emailed her my RQ "How does vitamin C, B and multivitamin affect the rate of growth of Solanum lycopersicum?" She told me the topic is good, however the RQ is not developed enough. Can anyone please tell me what I need to add to fix my RQ????
Thanks in advance!!!!!
