Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

Resting metabolic rate can vary with age independently from body mass changes in the Colorado potato beetle‚ Leptinotarsa decemlineata. Abstract A study was done by Saija Pironine‚ leena Lindstrom‚ and Anne Lyytinen in the Journal of Insect Physiology‚ to investigate the age dependence of resting metabolic rate in Colorado potato beetle (Leptinotarsadecemlineata) from adult emergence until age 10 days. In their hypothesis they expected to see a bell shaped pattern in metabolic rate with adult age

temperature)‚ and 70°C. This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again weighed to determine the amount of mass that they lost/gained and thus get an indication of the rate of osmosis. The results collected showed that the rate of osmosis was highest in the 70°C solution and lowest in the 20°C solution

The respiratory rate is a very important tool through which it is possible to recognise early signs of deterioration of a patient (Philip‚ Richardson & Maurice Cohen 2013‚ p. 570). Despite this‚ there is an increasing amount of cases in which healthcare professionals‚ nurses in particular‚ do not routinely assess and document this important vital sign correctly (Massey & Meredith 2010‚ p. 538).
