We observed … Hypothesis: if pillbugs are being experimented on their preference of lightness or darkness then the pillbugs will refer the darkened chamber because their natural habitats involve dark, moist environments. The second hypothesis is if the peas are germinated, then cellular respiration should happen at a faster rate compared to the non-germinated peas. Elements like wet peas, will undergo more respiration than there dry, non-germinating peas. Two people researched the Replication-First Hypothesis, and the other two researched the Metabolism-First Hypothesis.
