EXPERIMENT 1 COLLIGATIVE PROPERTIES OF SOLUTIONS Date: December 03‚ 2013 Locker 21 Members: Vanessa Olga Dagondon Christine Anne Jomocan Janica Mae Laviste Nablo Ken Menez A. TYPES OF DISPERSED SYSTEMS Results and Discussion The first part of the experiment aims to differentiate the different dispersion systems. In this experment‚ three systems are introduced: true solution‚ colloidal dispersion and coarse mixture. The said three systems are classified through a property of colloids known as the

Ways that plants cope with saline environments Introduction There are a lot of plants in this world managed to grow in different kind of environments by adapting to those environments in certain ways. In this essay‚ plants grow in environment with different salinity are concerned. Plants can be divided into two different groups when it comes to salinity. The first type of plants is the plants that grow and reproduce in saline environment which are called halophytes (Jefferies. 1981). Whereas

Very small molecules like water‚ electrolytes‚ glucose‚ fatty acids‚ amino acids‚ nitrogenous wastes‚ and vitamins can pass through the filtration membrane into the Bowman’s capsule. These substances have about the same concentration in the glomerular filtrate as in the blood plasma. Some substances do not pass through the membrane which makes them to be retained in the bloodstream because they are bound to plasma proteins. For example‚ most calcium‚ iron‚ and thyroid hormone in the blood
