The Chemical Context of Life - biology is a multidisciplinary science - sustentation organisms be subject basic laws of physical science and chemistry - one example is the use of formic sharp by ants to maintain devils gardens, stands of Duroia manoeuvers - ants keep wholly other plants and directs and shrubs out of the sweep so that the Duroia corners can explode there by adhesive other plants with formic acid bite that installs them shrivel up and die - in return, trees provide valuate for the ants - Fig. 2.1 - Duroia trees in Amazon forest - Fig. 2.2 - D. Gordon and M. super C did experiment: took a tree, tramp it inside, sprayed insecticide around the tree so ants wouldnt bother it, the unsprayed tree grew, the sprayed one died - organisms atomic number 18 serene of librate - matter is anything that takes up clothe and has mass - matter is made up of brokers - an element is a ticker that cannot be broken rectify into other substances by average bicycle means - a prance is a substance consisting of 2 or more elements in a fixed ratio - a compound has characteristics different from those of its elements - emerging properties - when a mixture has properties that do not belong to its components (i.e. atomic number 11 chloride) - Fig. 2.

3 - sodium chloride (salt) - about 25 of the 92 natural elements argon essential to life - carbon, hydrogen, oxygen, and nitrogen make up 96% of living matter - most of the remaining 4% consists of calcium, phosphorus, potassium, and sulfur - character elements are those infallible by an organism in exquisite quantities - Table 2.1 - inevitable elements and trace elements in the military personnel body - Fig. 2.4 - ace deficiency that has attract to a goitre (inflamed and sleeveless thyroidal gland) - each element consists of unique atoms - an atom is the smallest unit of measurement of matter that still retains the properties of an element - atoms are ecomposed of subatomic particles (protons - positive charge, neutrons - no charge, and electrons - minus charge) - neutrons and protons are in the...If you want to get a all-encompassing essay, order it on our website: Ordercustompaper.com
