The relationship between shape and diffusion rate Aim- To investigate the relationship between the shape of an object and the time taken for a substance to diffuse to its centre. Hypotheses- Part A) The 5x5x2.5mm block will turn clear first as the Surface area to volume ratio is high and the 10x10x10mm block will take the longest to completely diffuse the Acid to its centre. Part B) The flat‚ rectangular block will be the first to completely turn clear due to its high Surface Area/Volume Ratio

Homeostasis The ability of the body to maintain physiological parameters necessary for the preservation of life within a narrow range is referred to as homeostasis. In health‚ to a certain extent‚ the body can cope with this alteration and can constantly regulate the physiological changes in response to fluctuations in the external environment. For example‚ the maintenance of normal partial oxygen and carbon dioxide pressure‚ the right concentration of nutrients and waste products‚ the normal

Bodily responses to music Our body is a very sensitive being. When certain music is played it gets bodily reactions. Some music will make you laugh while some might make you cry. This chapters discusses how music effects the body and why. Music effects in two main ways; physiologically and physically. The first way we respond physiologically‚ which can be found in numerous ways. Physiological responses include internal bodily process.This would include heart rate‚ blood pressure‚ respiration

Homeostasis is the tendency of an organism or a cell to regulate its internal conditions‚ usually by a system of feedback controls‚ so as to stabilize health and functioning‚ regardless of the outside changing conditions. Humans use homeostasis to regulate control systems such as body temperature‚ osmotic balance‚ blood pressure‚ blood glucose and respiratory gases in tissues. This report will focus on thermoregulation‚ which is the ability of an organism to keep its body temperature within certain
