That's why I always recommend starting with a blog or website first. Create a content website on a very focused theme/niche. Build up traffic to that website through continuous, useful updates. Learn how to market the website, and as your following grows, then you'll have people to promote your social network to.
Human body. The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body. It comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet.
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent). Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All are necessary to life.n fact, 90% of the cells in (or on) a human body are microbes, by number (much less by mass or volume).
