The answer is a scanning tunneling microscope.
The scanning tunneling microscope that uses a probe to map atoms on the sur<span>face of a specimen. It has a good resolution (0.1 nm in lateral resolution, and 0.01 nm in depth resolution). It was named tunneling because, after a voltage is applied, electrons tunnel through the vacuum in between.</span>

Explanation
I just took the test and got it right!!!
Calcium ions are stored in the sacoplasmic reticulum. Sarcoplasmic reticulum plays an important role in storage and also acts as a release site for calcium. When calcium is released by the sarcoplasmic reticulum into the muscle it binds to the troponin, thus causing the tropomyosin to shift from the face of the actin filament to which myosin heads need to bind to produce a contraction.
