Can you modify this experiment so that the mass lifted by the muscle contraction continues to increase for every trial? If yes, explain how it should be modified. If no, explain why. Muscle ContractionIn an experiment, the strength of a neural stimulus and the resulting muscle contraction are compared. A single motor neuron that synapseswith one muscle fibre is observed in this experiment. One end of the muscle fibre is attached to a mass. The following data were obtained fromthe experiment.Analyze the data and answer the following questions.Number of TrialsStrength of Stimulus (mV)Mass Lifted by Muscle Contraction (g)12024036050480505100Not Tested612050*note that the voltage applied is positive in order to raise potential from resting to threshold

A study of muscle fibers between chimpanzees and humans revealed that although muscle mass per body size are approximately equivalent, the ratio of red (slow) and white (fast) fibers were significantly different. Chimps tend to have a ratio of 30% red to 70% white where humans are 60/40 respectively. Speculate about what this ratio difference means in terms of muscle activity potential and a possible evolutionary significance of this difference.

What methods can you use to test if someone has more fast twitch versus slow twitch muscle fibers? Remember the variances between fast twitch and slow twitch muscle fibers.
