Students will also develop scientific thinking skills, which they may apply when designing experiments that implement the most efficient investigative strategies. Vasoconstriction narrows the blood vessels near the skin and the rate of heat loss is reduced.
This depends on the calibre of the university you are targeting or the course you are hoping to get into. Can I register for some exams with ITS as a private candidate? Phototropism A tropism growth or movement in response to light.
Chloroplasts The organelles where photosynthesis takes place. For example, a gene causing baldness would mask the effect of a hair-colour gene. Papers can also be purchased from the exam boards. The walls of the alveoli are only one cell thick, and are surrounded by capillaries. The green pigment chlorophyll, found in chloroplasts, absorbs light energy for photosynthesis.
Concentration gradient The gradient between an area where a substance is at a high concentration and an area where it the substance is at a low concentration. Mitochondria Organelles responsible for aerobic cellular respiration in cells.
This coordinates all the information and sends a message to the effectors to bring about a response. Completing the correct sequence of units at both AS and A2 level means you have finished a full International A-level in a subject.
So if I want to study for some or all of my secondary education in the UK, what can I expect? The phloem is made of living cells that are joined to each other by holes that connect the cytoplasm together, forming a continuous system of living material to transport sugar and other nutrients.
The gene is cut open using restriction enzymes and then inserted into the new host organism, then DNA ligase is used to join the DNA back together. The parent cell divides twice to give four non-identical daughter cells with half the number of chromosomes as the parent cell.
You can find out the current fees, or check for the availability of a class here. Parthenogenesis The development of the embryo from an unfertilized egg. Students who attend a state-funded school receive their education free of charge.
Active transport is used to move substances from a low to a high concentration. Fermenters can be used to make mycoprotein, enzymes or drugs such as insulin. Variation, Inheritance and Evolution There is variation in members of a species. There are of course a range of other qualifications which students might take and which articulate with a number of higher education pathways.
Variation can be continuous showing a range of phenotypes, such as height or discontinuous phenotypes fall into distinct categories, such as blood group. Dihybrid cross A mating in which the parents differ with respect to two genetically inheritable traits. Imprinting Behaviour determined by exposure to stimuli at an early stage of development for example, a duckling will follow the first living object it perceives to be its mother.
If a mutation occurs in a gamete, the offspring may develop abnormally and pass on the mutation to their own offspring.
The UK has compulsory education for all students between the ages of 5 and Blood enters the left atrium through the pulmonary vein, and is pumped to the body through the aorta.
The Nervous System All living organisms can respond to their environment sensitivity.
He has also had the opportunity to present his research findings at a number of international conferences. Students in other educational systems or taking subjects in a different context may only need to take one or two subjects.
Biology Our tutorial lessons shall focus on teaching students to use scientific vocabulary when writing analysis, evaluation, and examination answers.
Contact the exam board and they will help you to obtain another one. Male sex hormones increase muscle growth and aggression. In shoots, auxin accumulates on the dark side of the soot. International A-levels can be used to access university courses. Osmosis The passive movement of water from an area of high concentration of water to an area of low concentration of water along a concentration gradient.
Stem cells Undifferentiated cells that have the potential to form a wide variety of different cell types. Biology A-Level Dictionary Action potential A rapid change in the electrical potential across a plasma membrane that occurs when the cell has been activated by a stimulus.
Groups of organs work together in organ systems. Enzymes are very specific for their substrate due to their shape. Phylogeny A hypothetical reconstruction of the evolutionary relationships of a group of organisms usually presented in the form of a tree.Recent Papers.
