The answer is myosin. Myosin are contractile protein the makes up thick filament. The molecule consists of a tail and two myosin heads which bind to myosin binding sites on actin molecules of thin filaments during muscle contraction. Actin on the other hand are contractile proteins that are the main component of thin filament. Each actin molecule has a myosin-binding site where myosin head of thick filament binds during muscle contraction.
On a graph of temperature vs. time, it shows pure substances exhibit a sharp boiling point and a sharp melting point as a horizontal flat line wherein the temperature does not change over time up until all the pure substances boiled or melted. The temperature stays stable at 160°C between 4 minutes and 11 minutes. This horizontal flat line part of the graph is normal of a pure substance. The melting point of a solid substance is usually used to specified if the substance is pure. Likewise, the boiling point of a "liquid" substance can be used to specify if the substance is pure as well.
