Simplifying Algebraic Equations
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.
Mitosis Revision Notes and Practice Quiz
The mitosis process produces two identical diploid cells for the purpose of growth and repair after cell division.
Osmosis Quiz
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.
Active Transport Revision Notes and Practice Quiz
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.
Percentages: Maths
To get you introduced to percentages, we will go through 3 different types of percentage questions that come up in GCSE Maths.
Microscopy: Biology
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.
Energy Stores: Revision Quiz
Learning and revising the topic of energy stores can be daunting, but it can become more manageable with the right tools and knowledge. These questions are designed to help students understand and learn the fundamental concepts of energy stores.
Energy Stores
We use energy to fuel movement and light, which can be found in various forms, such as light waves, heat waves, sound waves and kinetic energy. When we use energy, it is not destroyed but transferred from one entity or energy source to another.
Non-Communicable Diseases
Non-communicable diseases are diseases that cannot be caught from another person or animal. Cancer is a good example of non-communicable disease.
Cardiovascular Disease
The heart and blood vessels can be affected by many things. Many of these issues can be effectively treated if you know how.
Health and Disease
Poor health can be caused by diseases. Often, different diseases interact, and this can lead to further health complications that don't seem related at first.
Transpiration and Translocation
Animals and plants both have transport systems for moving substances around. Water is transported from the roots to the leaves during transpiration in xylem vessels for photosynthesis. All cells inside phloem vessels use glucose made during photosynthesis for respiration.
