Nicoyan pottery. Mesoamerican-style Nicoyan pottery at the Los Angeles Art Museum. Ceremonial Nicoyan metate. The Kingdom of Nicoya (from Nahuatl: Nekok Yaotl), also called Cacicazgo or Lordship of Nicoya, was an indigenous nation that comprised much of the territory of the current Guanacaste Province, in the North Pacific of Costa Rica.
A few elements have been found to have a pharmacologic function in humans (and possibly in other living things as well; the phenomenon has not been widely studied). In these, a normally nonessential element can treat a disease (often a micronutrient deficiency). An example is fluorine, which reduces the effects of iron deficiency in rats.
This designation is granted to global regions that are characterized by the longest life expectancies. Among the ideal Nicoyan lifestyle characteristics cited by the research were the water's high calcium and magnesium content, intense daily physical activity, year-long fruit consumption, and close inter-generational relationships.
Biomolecules and their reactions are studied in biology and its subfields of biochemistry and molecular biology. Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass. But many other elements, such as the various biometals, are also present in small amounts.
For example, a molecule can be viewed as a grouping of elements, and an atom can be further divided into subatomic particles (these levels are outside the scope of biological organisation). Each level can also be broken down into its own hierarchy, and specific types of these biological objects can have their own hierarchical scheme.
Others were reclassified in kingdom Protozoa, like Metamonada which is now part of infrakingdom Excavata. Because Cavalier-Smith allows paraphyly, the diagram below is an "organization chart", not an "ancestor chart", and does not represent an evolutionary tree.
This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
