AQA Biology third edition textbook-Page 304-307 Students are required to know the following; 7.5.1 Students should be able to describe some of the biological factors affecting levels of food security. Food security is having enough food to feed a population. Biological factors which are threatening food security include: • the increasing birth rate has threatened food security in some countries • changing diets in developed countries means scarce food resources are transported around the world • new pests and pathogens affect farming • environmental changes affect food production, such as widespread famine occurring in some countries if rains fail • cost of agricultural inputs • conflicts have arisen in some parts of the world over the availability of water or food. Sustainable methods must be found to feed all people on Earth. 7.5.2 The efficiency of food production can be improved by restricting energy transfer from food animals to the environment. This can be done by limiting their movement and by controlling the temperature of their surroundings. Some animals are fed high protein foods to increase growth. 7.5.3 Fish stocks in the oceans are declining. It is important to maintain fish stocks at a level where breeding continues or certain species may disappear altogether in some areas. Control of net size and the introduction of fishing quotas play important roles in conservation of fish stocks at a sustainable level.

AQA Biology trilogy edition textbook-Page 240-241 Students are required to know the following; Students should be able to: • describe the work of Darwin and Wallace in the development of the theory of evolution by natural selection • explain the impact of these ideas on biology. Alfred Russel Wallace independently proposed the theory of evolution by natural selection. He published joint writings with Darwin in 1858 which prompted Darwin to publish On the Origin of Species (1859) the following year. Wallace worked worldwide gathering evidence for evolutionary theory. He is best known for his work on warning colouration in animals and his theory of speciation. Alfred Wallace did much pioneering work on speciation but more evidence over time has led to our current understanding of the theory of speciation. Students should be able to describe the steps which give rise to new species. WS 1.1 The theory of speciation has developed over time

NB: If you are unable to play embedded videos please view slide notes for link. * AQA spec link: 4.7.3.1; 3.2; 3.3 Relevant chapter: B18 Biodiversity and ecosystems. AQA Biology third edition textbook-Page 286-287 Students are required to know the following; Biodiversity is the variety of all the different species of organisms on earth, or within an ecosystem. A great biodiversity ensures the stability of ecosystems due to the interdependencies of one species on another for food, shelter, and the maintenance of the physical environment. The future of the human species on Earth relies on us maintaining a good level of biodiversity. Many human activities are reducing biodiversity and only recently have measures been taken to try to stop this reduction. Rapid growth in the human population and an increase in the standard of living mean that increasingly more resources are used and more waste is produced. Unless waste and chemical materials are properly handled, more pollution will be caused. Humans reduce the amount of land available for other animals and plants by building, quarrying, farming, and dumping waste.

Removing waste products lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations and worksheet. AQA spec link: 5.3.3 Relevant chapter: B12.2-Removing waste products . ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 184-185 *The new specification requires students to know the following; Students should be able to explain the effect on cells of osmotic changes in body fluids. Water leaves the body via the lungs during exhalation. Water, ions, and urea are lost from the skin in sweat. There is no control over water, ion, or urea loss by the lungs or skin. Excess water, ions, and urea are removed via the kidneys in the urine. If body cells lose or gain too much water by osmosis they do not function efficiently. The digestion of proteins from the diet results in excess amino acids which need to be excreted safely. In the liver these amino acids are deaminated to form ammonia. Ammonia is toxic and so it is immediately converted to urea for safe excretion.

Evidence for evolution lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability class, although content can be adjusted to suit any ability. Includes: embedded videos and timers, slide animations, practice questions with answers on slides, worksheet and an interactive quiz. NB: If you are unable to play videos a URL link can be found in the slide notes. AQA spec link: 4.6.3.4 Relevant chapter: B15 Genetics and evolution. AQA Biology third edition textbook-Page 242-243 Students are required to know the following; Students should be able to describe the evidence for evolution including fossils and antibiotic resistance in bacteria. The theory of evolution by natural selection is now widely accepted. Evidence for Darwin’s theory is now available as it has been shown that characteristics are passed on to offspring in genes. There is further evidence in the fossil record and the knowledge of how resistance to antibiotics evolves in bacteria.

Stem cells dilemmas lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability separates class, although content can be adjusted to suit any ability. Includes: slide animations, embedded video, practice questions with answers on slides. AQA spec link: 4.1.2.3 Relevant chapter: B2 Cell division. AQA Biology third edition textbook-Page 32-33 Specification requires students to know the following; In therapeutic cloning an embryo is produced with the same genes as the patient. Stem cells from the embryo are not rejected by the patient’s body so they may be used for medical treatment. The use of stem cells has potential risks such as transfer of viral infection, and some people have ethical or religious objections. Stem cells from meristems in plants can be used to produce clones of plants quickly and economically. •• Rare species can be cloned to protect from extinction. •• Crop plants with special features such as disease resistance can be cloned to produce large numbers of identical plants for farmers.

The human Kidney lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). This is a printer friendly resource it includes an: embedded video, slide animations and a mini exam question. As i taught this lesson in two parts it's only fair i upload the other presentation also (2 for the price of 1). **Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required.** AQA spec link: 5.3.3 Relevant chapter: B12-Homeostasis in action. ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 185-186 *The new specification requires students to know the following; Students should be able to describe the function of kidneys in maintaining the water balance of the body. The kidneys produce urine by filtration of the blood and selective reabsorption of useful substances such as glucose, some ions, And water. Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required. Students should be able to translate tables and bar charts of glucose, ions, and urea before and after filtration. Students should be able to describe the effect of ADH on the permeability of the kidney tubules. The water level in the body is controlled by the hormone ADH which acts on the kidney tubules. ADH is released by the pituitary gland when the blood is too concentrated and it causes more water to be reabsorbed back into the blood from the kidney tubules. This is controlled by negative feedback.

Uses of monoclonal antibodies lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability SEPARATE (trilogy) class, although content can be adjusted to suit any ability. Includes: slide animations, embedded videos,questions with answers on slides and homework, with mark scheme. NB: This resource is for separate science only AQA spec link: 4.3.2.2 Relevant chapter: B6 Preventing and treating diseases. AQA Biology third edition textbook-Page 107-109 Specification requires students to know the following; Students should be able to describe some of the ways in which monoclonal antibodies can be used. •To treat some diseases: for cancer the monoclonal antibody can be bound to a radioactive substance, a toxic drug or a chemical which stops cells growing and dividing. It delivers the substance to the cancer cells without harming other cells in the body. Students are not expected to recall any specific tests or treatments but given appropriate information they should be able to explain how they work. Monoclonal antibodies create more side effects than expected. They are not yet as widely used as everyone hoped when they were first developed.
