Practical 2: Metabolic rate in selected invertebrates. Ayman Shaik Abstract In this experiment was designed to determine the metabolic rate of three small invertebrates in relation to the animal?s body mass. The hypotheses for this experiment would be that the animal with the highest Oxygen consumption, would have the highest metabolic rate. The above hypothesis is accepted. The cockroach of the mass 1,07g, has an Oxygen consumption of 4,8ml and the highest metabolic rate of Introduction
