Biology Tuition Singapore – Animal Nutrition Misconceptions     Misconception 1 Digestion is the process of releasing energy from food. Correct Concept Actually digestion has no direct connection to the release of energy. That is the role of respiration. However, digestion facilitates the release of energy by turning food into a more accessible form that can be used by cells to obtain energy     Misconception 2 Peristalsis occurs only in the oesophagus Correct Concept Peristalsis also occurs in the small and large intestines. It ensures the smooth and efficient removal of undigested matter in the large intestine (egestion). This is necessary to avoid excessive dehydration of the undigested matter, which could cause constipation.   Please contact Angie @ 96790 ...

Correct Concept   Both the relative atomic mass and the relative molecular mass have no units. Thus, the relative molecular mass of water is just 18.   Misconception 2   The mass of one hydrogen atom is 1.0 g. Correct Concept The mass of 1.0 mol (6 x 1023) hydrogen atoms is 1.0 g.   Please contact Angie @ 96790479 or Mr Ong @ 98639633 if you need Secondary 3-5 or O level or N level Chemistry Tuition /Secondary Physics Tuition

Physics Tuition Singapore – Energy,Work and Power Misconceptions   Misconception 1 Kinetic energy is a vector quantity and its direction is the same as the direction of motion of the object. Correct Concept Kinetic energy is a scalar quantity and does not have direction. Its magnitude depends on mass and speed (which is equal to the magnitude of velocity).   Misconception 2 A car travels from the top of a hill down a slope. Neglecting frictional forces, the final kinetic energy of the car is equal to the loss of potential energy. Correct Concept A car travels from the top of a hill down a slope. Neglecting frictional forces, the increase in kinetic energy of the car is equal to the loss of potential energy. Therefore, the final kinetic energy = initial kinetic energy – ...
