From Research Question to Null Hypothesis Here’s a chance for you to test your understanding of hypotheses. Can you develop null hypotheses based on the research questions below? An experiment has been designed to investigate the effects of proposed climate change, in particular warmer spring temperatures, on the growth and development of lambs. High levels of iron sulfate are thought to have a detrimental effects upon the population dynamics of water fleas (Daphnia magna). An experiment was designed to investigate the effects of high phosphorous concentration on female Daphnia egg production. Dung beetle colonisation and activity is thought to be influenced by not only the quality of the dung, but also the size of the dung pat. An experiment was designed to investigate the relationship between beetle colonisation and the dung pat.
