Another term commonly used to describe hypervariable loops is Select one: a. signal joint. O b. framework regions c. multivalency d. hinge region e. complementarity-determining regions

1. You wish to use the polymer ultra-high-molecular- weight polyethylene (UHMWPE) as a scaffold to make a new tendon. a) You wish to modify the surface to help tenocytes and tenoblasts (cells that usually reside in the tendon) attach to the material. How can you do this?

What are the steps of the sliding filament model? Select all that apply. Sarcomeres are in a relaxed state, in which myosin-binding sites on actin are blocked. When a nervous signal excites the muscle, myosin-binding sites on actin open up and myosin binds to actin. The myosin heads hydrolyze ATP to ADP and P. The binding of myosin to actin releases phosphate and triggers a power stroke. ATP binds to myosin, and the myosin releases its grip on actin, returning to a relaxed state.
