Tuition Center Singapore Biology Tuition – Cell Structure and Organisation    Common Error 1 Since cell walls are rigid, they should be impermeable. Correct Concept 1 The rigidity of a structure is not indicative of its permeability. The rigidity of cell walls is useful in maintaining the turgidity of plants and preventing the bursting of the cell.   Common Error 2 Cells are the same as molecules Correct Concept 2 Cells are not the same as molecules. In fact, cells (living) are made up of non-living molecules. The relative sizes of cells range from 1-100 pm (10-6 m) while molecules are much smaller, in the range of picometers (10– ‘2m) for those like water and in nanometers (10-9m) for some like haemoglobin.   Common Error 3 Living things contain cells Corr ...

Tuition Center Singapore Physics Tuition – Kinematics Definitions Displacement is the measurement of distance from a reference point to another point in a certain direction. The SI unit of displacement and distance is metre (m). Velocity is the rate of change of displacement. Speed is the rate of change of distance. Velocity is a vector quantity whereas speed is a scalar quantity. Speed is the magnitude of velocity. The SI unit of velocity and speed is metre per second (m/s or m s-1). For constant speed, its value is given by: Speed  =  distance travelled / time taken           For non-constant speed, the average speed is given by:           Average speed = total distance travelled / total time taken.   Please contact Mr Ong @ 9863 9633 or Angie @ 96790479 if you need help in O ...

Tuition Center Singapore Chemistry Tuition – Experimental Techniques Important Definitions   Filtrate is the liquid that passes through the filter paper. Distillation is a technique for separating a liquid by boiling the liquid and condensing the vapour. The distillate is the product obtained from condensation during distillation. Residue is the solid that remains on the filter paper after filtration, or the solid that remains in the distillation flask after distillation. Fractional distillation is a technique for separating a mixture of liquids with different boiling points. In fractional distillation, the distillation apparatus is fitted with a fractionating column. A pure substance is a single substance that is not mixed with other substances. Chromatography is a technique of using ...
