Document Summary

High dietary fiber intake can interfere with the absorption of zinc. Selenium is the only mineral that functions as an antioxidant. Soluble minerals dissolved in the ocean: ex. 60 ml of h2o taken from the shores of nj on hot plate evaporate heat scrape mineral material 3. 5% salt by weight = the amount of mineral/salt material dissolved in the ocean. The galapagos islands: ~ 1000 km off the shores of ecuador, iguanas, the blue footed booby bird. Elements vs salts (ions): ion: electrically charged atom formed by the loss or gain of one of more electrons, ca2+, mg2+, na+, k+: have outer e- that can be removed combine with negatively charged species hco3. Periodic table: vertical: similar properties (ex. F, cl, br, i, al) can gain an e- and become negatively charged: horizontal: changing the element as the atomic # increases (ex. Nucleus is composed of protons (+ charged species: proton determines the element (ex.
