Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it that govern all study and research‚ consolidating it into single‚ coherent field. In general‚ biology recognizes the cell as the basic unit

Biology – HSC Online Extract from Biology Stage 6 Syllabus (Amended October 2002) © Board of Studies‚ NSW 9.2 Maintaining a balance: 1. Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

My hypothesis for this Experiment is that a mineral is able to scratch a mineral with a lower number and can‚ therefore be scratched by a mineral with a higher number. A mineral’s density is the amount of matter in a given space (mass/volume). Each mineral has a characteristic density (density
