Neurones Basic cells of the nervous system that carry minute electrical impulses around the body. Cystic fibrosis is a recessive disease that affects the lungs and digestive system. Scientists have decoded all the bases in the human DNA, so we now have a genetic map of all genes. When we feel cold, shivering increases the rate of respiration and more energy is released as heat.
Once the mRNA leaves the nucleus, it enters a ribosome where a protein is made from the encoded message. During fertilization, different traits are inherited independently of each other law of independent assortment.
Ribosomes The site of protein synthesis in a cell, found in the cytoplasm. Epistasis The masking of one gene by another. Groups of organs work together in organ systems. Can I retake an exam if I am unhappy with my mark?
At Key Stage 3 KS3student will learn cellular, skeletal and muscular systems of living organisms; nutrition, digestion, and excretion; respiration and photosynthesis; health and disease; reproduction in plants and humans; ecosystems, habitats, food chains and food webs; genetics, inheritance, selective breeding, variation, evolution, extinction, and biodiversity; human impact on the environment; nerves and hormones; and transport.
Some variation is genetic or inherited from our parents, while some is a result of our environment. Mutation is a change in DNA, that can be caused by radiation including X-rays and UV light from the sun and chemical mutagens as in cigarettes.
Diffusion increases with temperature and with smaller particles, which move faster. Hemoglobin The red pigment which carries oxygen around the body, found in red blood cells. The first difference is that online learning must use the internet whereas distance learning can use other methods to deliver learning material.
When the diaphragm contracts and the intercostal muscles contract, the volume of the pleural cavity increases, reducing the pressure. A-level students usually have free choice over the subjects they wish to study, although it is also important to bear in mind any pre-requisite subjects required for your target university course.

Have a look at our UCAS information pages here and here. Atrioventricular AV valves also known as the bicuspid valve on the left and the tricuspid valve on the right close when the ventricles are pumping, to prevent blood from returning into the atria. Calvin cycle also the dark reaction or the light-independent reaction A series of biochemical reactions taking place in the stroma of the chloroplasts, resulting in carbon fixation.
A-levels and the IB Diploma are both ways to show you have completed high school and are both used to qualify for university entrance. This is regulated by both the nervous system and the endocrine system. Adaptations Special features which make an organism particularly well suited to its habitat.
This coordinates all the information and sends a message to the effectors to bring about a response. Parasites are larger than microbes. Single nucleotide polymorphism SNP DNA sequence variations that occur when a single nucleotide in the genome sequence is altered.
Food is burnt in a closed container, and the temperature rise in the surrounding water is measured. Most qualifications from the English boards are also available, with the exception of English language and the sciences, due to requirements for speaking and practical assessment, respectively.
Children usually begin primary school at five years old and generally move to secondary school when they turn eleven. There is also sometimes an interview. Rods and cones are the receptor cells that are concentrated in the fovea of the retina. Bacteria use mitosis as a form of reproduction asexual reproduction.
You can apply as soon as you are 16, provided you have the relevant qualifications. Charles Darwin developed the theory of evolution by natural selection. Dr Szeto has been awarded numerous scholarships and prizes for both research and academic excellence. Phytochrome A photoreceptor a pigment that plants use to detect light.
Temperature receptors send nerve impulses to the skin, which help to regulate our body temperature.Online learning brings school to you.
You may live in a remote area, have restricted school choice nearby, have mobility issues, or simply prefer the home-schooling option but would like teacher support.
The Oxford Open Learning Trust’s international GCSE Biology course is designed to follow the structure of the Edexcel 4BI0/4BI1 specifications and is divided into five modules, as follows. Online GCSE and IGCSE courses.

The International General Certificate of Secondary Education (IGCSE) is an English language curriculum offered to students to prepare them for International Baccalaureate, A Level and BTEC Level 3 (which is recommended for higher-tier students).
