Describe how your biceps muscle contracts IN SERIES AT CELLULAR & MYOFIBER LEVELS when you drink a cup of coffee. You should include the following concepts: - How resting membrane potential is negatively charged in the cell - Depolarization and repolarization of the cells - How neural signal (a motor neuron) is sending to skeletal muscular cells - Include the roles of T-tubule, SR, Calcium ions, thick/think filaments, cross bridge, power stroke, ATP in muscle contraction

1. In your own words, describe how you would use the activity series provided to you in your course to determine that the reaction of calcium with copper (II) nitrate occurs. 2, Calculate the number of moles in a 14.6 g sample of calcium carbonate (CaCO3). calculate the number of calcium atoms in that sample. 3. Calcium carbonate is formed from the reaction of solid calcium oxide with carbon dioxide in the atmosphere. Write the balanced chemical equation to illustrate...
