Tuition Singapore Secondary Math Tuition -Prime Numbers, Prime Factorisation and Index Notation Note : 0 and 1 are neither prime nor composite numbers   A prime number is a whole number greater than 1 that has exactly two different factors, 1 and itself. E.g. 5 = 1 x 5 Since 5 has no other whole number factors other than 1 and itself, it is a prime number. The numbers 2, 3, 5, 7, 11, 13, 17, … are prime numbers. A composite number is a whole number greater than 1 that has more than 2 different factors. E.g. 6 = 1 x 6 6 = 2 x 3 4 factors   6 is a composite number. The numbers 4, 6, 8, 9, 10, 12, 14, 15, 16, … are composite numbers. In other words, all whole numbers greater than 1 that are not prime numbers are composite numbers.      5. Prime factors are factors of a n ...

Tuition Singapore Secondary Science Tuition – How to design a good experiment During the planning of an experiment, it is important to identify and to control the variables. Variables are factors/conditions which have an effect on the experiment. It is important to know the cause and effect relationships between the variable you change and the variable you are measuring in the experiment. There are three types of variables: Independent variable (what you change) Dependent variable (what you observe/measure) Controlled variable (what you keep the same) Please contact Angie @ 96790479 or Mr Ong @ 98639633 if you need to know more about Lower Secondary Science Tuition

Tuition Singapore H2 H1 Biology Tuition – Cellular Respiration   Question Describe the process of oxidative phosphorylation in the mitochondrion. Answer  NADH and FADH2 as electron donors to the electron transport chain in inner mitochondrial membrane Electrons lose energy as they are passed down a series of electron carriers of progressively lower energy level Energy released is used to actively transport protons via proton pump From matrix to inter-membrane space Generate proton gradient across the inner membrane Protons transported via proton channel of ATP synthase Via facilitated diffusion / down concentration gradient / chemiosmosis Proton motive force ATP synthesized from ADP and Pi by ATP synthase Oxygen as final electron acceptor of the ETC Combines with protons to form water ...

Tuition Singapore H2 Economics – Distinguish between public goods and merit goods.   Model Answer   Public goods are goods that are non-rivalrous in consumption and non excludable as well whilst merit goods are goods deemed socially desirable for individuals by one’s government.
