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?
In prokaryotic cells (such as bacteria) that do not have a membrane-bound nucleus, the cytoplasm consists of all of the contents of the cell inside the plasma membrane. In euckaryotic cells, (such as plant and animal cells) the cytoplasm consists of three main components. They are the cytosol, organelles, and various particles and granules called cytoplasmic inclusions. Cytosol. The cytosol is the semi-fluid component or liquid medium of a cell's cytoplasm.
