The myelin sheath (C) insulates the axons.
The myelin sheath is a fatty substance, hence why it is great for insulation. <span />
The variable that researchers manipulate is the independent variable.
The reason for this is because in experiments different manipulations are often introduced. The sole purpose of these manipulations is to see whether they will affect our independent variable and if they will change its value.
The answer is isometric training. To simplify, the strength gains with isometric training are specific to the angle of muscle contraction. In addition, Isometric exercise or isometrics are a kind of strong physical activity in which the joint angle and muscle length do not alter throughout contraction likened to concentric or eccentric contractions or as called as dynamic or as isotonic activities.
When we discuss superposition in biology term then its principle tells that one by one rocks or sediments settles.The superposition mean that the older rocks or sediments place below all newly coming sediments or rocks place on first layer so layer over layer formation is called superposition.
