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.

Calculations involving very large or very small numbers can be simplified by converting them into and out of standard form. A number can be converted into standard form by splitting it into two parts - a number between 1 and 10 multiplied by a power of 10.
Mitosis is a type of cell division in which one cell, the mother, divides into two genetically identical daughters. The mitosis of the cell cycle refers to the process in which the DNA of the cell's nucleus is divided into two equal sets of chromosomes.

The cell's structure is related to the job it does, so cell structures vary from one another. When cells express specific genes that characterise a certain type of cell we say that a cell has become differentiated.
