Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 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 ...
The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae , the cells of which are receptive to pollen.
Bioarchaeology (osteoarchaeology, osteology or palaeo-osteology [1]) in Europe describes the study of biological remains from archaeological sites.In the United States it is the scientific study of human remains from archaeological sites.
The discovery of human bone fragments sent the researchers digging through the material excavated about nine decades ago — in which they found additional skeleton fragments.
The column, or technically the gynostemium, is a reproductive structure that can be found in several plant families: Aristolochiaceae, Orchidaceae, and Stylidiaceae. It is derived from the fusion of both male and female parts ( stamens and pistil ) into a single organ. [ 1 ]
The bones were determined to be up to 47,500 years old. Until now, the oldest Homo sapiens remains from northern central and northwestern Europe were about 40,000 years old.
Plant models are true to what scientists found in the region. There are diversions for younger kids, such as eye-level dioramas for toddlers and fossil identification games for older kids.
