They’re electromagnetic radiation wavelengths that are visible to most human eyes.
The butterfly effect!
The butterfly effect is a popular phenomenon that has remained out of the scope for science. The very definition of the butterfly effect seems to be debatable. Tiny changes in the initial condition of a large non-linear system like the functioning of the brain or the ecosystem can cause huge changes in the system itself. Example, the flapping of the wings of the butterfly can cause tornado in some other place. Given the extremely high complexity of the problem, the study of the dynamics of such a change to happen has remained out of the scope of science.
As hinted in the question, the cross bridge cycle is a
series of molecular events that occur after excitation of the sarcolemma. A
cross bridge is formed when a myosin head bound to actin. The cross bridge
cycle depends on the presence of calcium ions
