The amount of magnetic flux that rises up to the Sun's surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle. Near the minimum of the solar cycle, it is rare to see sunspots on the Sun, and the spots that do appear are very small and short-lived.
exists and is an alternate of . Making the world better, one answer at a time. The three main parts of the cell are the cell membrane (surrounds and protects the cell), the cytoplasm (the liquid inside the cell), and the nucleus (control center of the cell). Minor edit?
A simple structure designed for a complex task. A typical neuron is divided into three parts: the cell body, the dendrites and the axon. The cell body (green color), the center of the neuron, extends its processes called the axon and the dendrites to other cells.Dendrites typically branch profusely, getting thinner with each branching (blue color).etting really into it. The cell body is the central part of the neuron. It contains the nucleus of the cell (that carries all the genetic material) and numerous organelles that allow protein synthesis (endoplasmic reticulum, golgi, etc) and energy production (mitochondria).
