question 3

True/False

SCENARIO 15-3 A chemist employed by a pharmaceutical firm has developed a muscle relaxant.She took a sample of 14 people suffering from extreme muscle constriction.She gave each a vial containing a dose (X)of the drug and recorded the time to relief (Y)measured in seconds for each.She fit a curvilinear model to this data.The results obtained by Microsoft Excel follow SUMMARY OUTPUT
-Referring to Scenario 15-3, suppose the chemist decides to use a t test to determine if there is a significant difference between a linear model and a curvilinear model that includes a linear term.If she used a level of significance of 0.01, she would decide that the linear model is sufficient.

Understand the electrical properties of muscle cells, including action potentials, resting membrane potential, and the role of ion channels.

Describe how skeletal muscles receive stimulation from motor neurons and the importance of neuromuscular junctions.

Understand the mechanisms controlling muscle contraction, including the role of calcium ions and the sarcoplasmic reticulum.

Explain the concepts of depolarization and repolarization in the context of muscle action potentials and their relation to muscle contraction and relaxation.
