a. a significant feature of graded potentials.
b. Like graded potentials can sum to create a larger graded potential.
c. Graded potentials randomly occur all the time but are of no significance.
d. Like graded potentials will subtract from each other to create a smaller graded potential.
e. Graded potentials activate enzymes to excite the cell.

b

Explanation:

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
