Diffusion: Revision Notes
Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration. Diffusion occurs in liquids and gases when their particles collide randomly and spread out.

In order to understand anything in algebra, you have to have an understanding of what a term is. Terms are the building blocks of algebraic equations.
The mitosis process produces two identical diploid cells for the purpose of growth and repair after cell division.
The osmosis process involves the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low concentration.
By moving through the cell membrane, substances can enter and leave the cell. Three of the most common types of movement are diffusion, osmosis, and active transport.
To get you introduced to percentages, we will go through 3 different types of percentage questions that come up in GCSE Maths.
Microscopy is an essential tool for scientific research and analysis, allowing us to observe and study objects that are too small to be seen with the naked eye. GCSE Science students must understand the principles of microscopy and the different types of microscopes and their uses.
Solving linear equations involves finding the variable's value that makes the equation true. This can be done by simplifying the equation so that the variable is on one side of the equal sign and the constant is on the other side.
algebra factorising involves breaking down algebraic expressions into smaller parts or factors to simplify them. This can be done using various techniques, such as finding common factors, using the difference of two squares formula, or grouping terms.
Indices and roots are essential concepts in mathematics, and mastering them is crucial in GCSE mathematics. Knowing the laws of indices and understanding standard forms can help simplify complex calculations and make them more manageable.
Knowing the laws of indices and understanding standard forms can help simplify complex calculations and make them more manageable.
Linear equations are equations of the first order. These equations are defined for lines in the coordinate system.
Linear equations and word problems can help us make decisions in real-life situations by modelling scenarios with different variables. We can determine the best course of action or the most cost-effective solution by setting up equations and solving for the variables.
