Structure refers to how a text is organised and how its parts work together. The purpose of structuring a text is to influence the reader.
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.

Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life. Focusing on the cell permits a detailed understanding of the tissues and organisms that cells compose.
All living things are made of cells – they're the building blocks of every organism on the planet. But different organisms have different cell structures...
Microscopy is the objects, such study of very small as cells in science, using an instrument called a microscope.
The Farmer's Bride is a famous poem by Charlotte Mew. The narrator in the Farmer’s Bride provides a dramatic monologue in which a farmer in the nineteenth century reflects on his relationship with his wife.

The exchange surfaces are important because they allow oxygen to be exchanged for carbon dioxide. This process allows the body to get the oxygen that it needs.
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.
Undifferentiated cells are cells that haven't yet changed to become specialised for a particular task. They are called stem cells.
Angles are measured in degrees, written °. The maximum angle is 360°. This is the angle all the way around a point.
