Set a timer for 25 minutes (or your preferred interval length) to work on the chosen topic. Adjust the duration based on your concentration levels and the complexity of the topic, but remember that the standard interval is 25 minutes. 3. Work on the topic. Focus solely on the selected topic during the Pomodoro interval The lock-and-key hypothesis. Enzymes are globular proteins. This means their shape (as well as the shape of the active site of an enzyme) is determined by the complex tertiary structure of the protein that makes up the enzyme and is therefore highly specific. In the ’s the first model of enzyme activity was described by Emil Fischer Step 1: Determine the store that energy is being transferred away from, within the parameters of the defined system. For a battery powering a torch. The system is defined as the energy transfer from the battery to the torch, so this is the transfer to focus on. Therefore, the energy began in the chemical store of the cells of the battery Solve the simultaneous equations. Method 1: Elimination. Number the equations. Eliminate by adding equations (1) and (2). (1) + (2): Find a second equation in and by subtracting 2 times equation (1) from equation (3). (3) - 2 (1): Solve equations (4) and (5) using your preferred method of solving a pair of linear simultaneous equations Diffusion & Facilitated Diffusion. Diffusion is a type of transportation that occurs across the cell membrane. The net movement, as a result of the random motion of its molecules or ions, of a substance from a region of its higher concentration to a region of its lower concentration. The random movement is caused by the natural kinetic energy Answer. Maths GCSE - Circle Theorems. Maths GCSE - Trigonometry (Sin Cos Tan) Sin Cos Tan – GCSE Maths – Explained. Exam paper questions organised by topic and Learning Approaches. Alison is a Psychology teacher who is keen to reduce plastic waste in her school.

Filter the mixture into a test tube. This removes any debris (big, insoluble bits of cell) from the mixture. Gently add some ice-cold ethanol to the filtrate (the filtered mixture) by pouring the ethanol slowly down the side of the test tube. This causes the DNA to precipitate (i.e. to come out of solution) as DNA is not soluble in cold alcohol 1. Organise your study materials 2. Create a revision schedule 3. Familiarise yourself with your exam papers, format and timings 4. Use active recall techniques to consolidate knowledge 5. Practice past papers/topic questions 6. Balance work with healthy habits and rest 7. Review and self-test on a regular basis A) Find the mean and median times. There are a fair amount of numbers so it may be wise to do the adding up in bits - we've used rows. 12 + 10 + 15 + 14 + 17 = 11 + 12 + 13 + 9 + 21 = 14 + 20 + 19 + 16 + 23 = For the
