Introduction A computerized simulation experiment will be conducted in order to study the cell transport mechanism via the cell’s selectively permeable membrane and passive processes of simple and facilitated diffusion. The plasma membrane is a gateway which allows nutrients to enter the cell and keep undesirable substances out‚ hence‚ making it selectively permeable. One method of transport is called active transport‚ which uses ATP to transport substances through the membrane. The other is

CURRICULUM EVALUATION DEFINITION OF EVALUATION Curriculum evaluation is a systematic process of determining whether the curriculum as designed and implemented has produced or is producing the intended and desired results. It is the means of determining whether the program is meeting its goals‚ that is whether the measures / outcomes for a given set of instructional inputs match the intended or pre-specified outcomes. (Tuckman‚ 1979) Types of Evaluation 1. Humanistic approach – goal free

INTRODUCTION Osmosis is the movement of water molecules from high concentration to low concentration through semipermeable membranes‚ caused by the difference in concentrations on the two sides of a membrane (Rbowen‚ L.). It occurs in both animals and plants cells. In human bodies‚ the process of osmosis is primarily found in the kidneys‚ in the glomerulus. In plants‚ osmosis is carried out everywhere within the cells of the plant (World Book‚ 1997). This can be shown by an experiment with potato

Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly

Job Evaluation Methods There are three basic methods of job evaluation: (1) ranking‚ (2) classification‚ (3) factor comparison. While many variations of these methods exist in practice‚ the three basic approaches are described here. Ranking Method Perhaps the simplest method of job evaluation is the ranking method. According to this method‚ jobs are arranged from highest to lowest‚ in order of their value or merit to the organization. Jobs also can be arranged according to the relative difficulty

Substances‚ including water‚ ions‚ and molecules that are required for cellular activities‚ can enter and leave cells by a passive process such as diffusion. Diffusion is random movement of molecules in a net direction from a region of higher concentration to a region of lower concentration
