AQA spec link: 4.4.2.2 Relevant chapter: B9 Respiration. AQA Biology third edition textbook-Page 136-137 Students are required to know the following; During exercise the human body reacts to the increased demand for energy. The heart rate, breathing rate and breath volume increase during exercise to supply the muscles with more oxygenated blood. If insufficient oxygen is supplied anaerobic respiration takes place in muscles. The incomplete oxidation of glucose causes a build up of lactic acid and creates an oxygen debt. During long periods of vigorous activity muscles become fatigued and stop contracting efficiently. AT 1, 3, 4 Investigations into the effect of exercise on the body. (HT only) Blood flowing through the muscles transports the lactic acid to the liver where it is converted back into glucose. Oxygen debt is the amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from the cells.

AQA Biology combined edition textbook-Page 206-207 Students are required to know the following; Students should be able to describe: •different levels of organisation in an ecosystem from individual organisms to the whole ecosystem • the importance of interdependence and competition in a community. An ecosystem is the interaction of a community of living organisms (biotic) with the non-living (abiotic) parts of their environment. To survive and reproduce, organisms require a supply of materials from their surroundings and from the other living organisms there. Plants in a community or habitat often compete with each other for light and space, and for water and mineral ions from the soil. Animals often compete with each other for food, mates and territory. Within a community each species depends on other species for food, shelter, pollination, seed dispersal etc. If one species is removed it can affect the whole community. This is called interdependence. A stable community is one where all the species and environmental factors are in balance so that population sizes remain fairly constant.

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.

Edited 13/07/2020-PPT has been updated since last review, this resource also now includes a Control of BGL mini assessment with MS Control of blood glucose lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations, embedded video, practice exam question with mark scheme. This resource is suitable for combined science students. May needed to be edited for foundation students. AQA spec link: 5.3.2 Relevant chapter: B11 Hormonal coordination. AQA Biology third edition textbook-Page 162-163. Blood glucose concentration is monitored and controlled by the pancreas. If the blood glucose concentration is too high, the pancreas produces the hormone insulin that causes glucose to move from the blood into the cells. In liver and muscle cells excess glucose is converted to glycogen for storage. Students should be able to explain how insulin controls blood glucose (sugar) levels in the body. Type 1 diabetes is a disorder in which the pancreas fails to produce sufficient insulin. It is characterised by uncontrolled high blood glucose levels. In Type 2 diabetes the body cells no longer respond to insulin produced by the pancreas. Students should be able to compare Type 1 and Type 2 diabetes and explain how they can be treated. Students should be able to extract information and interpret data from graphs that show the effect of insulin in blood glucose levels in both people with diabetes and people without diabetes. (Will be incorporated in treating diabetes lesson). Higher content- If the blood glucose concentration is too low, the pancreas produces the hormone glucagon that causes glycogen to be converted into glucose and released into the blood. Students should be able to explain how glucagon interacts with insulin in a negative feedback cycle to control blood glucose (sugar) levels in the body. (Will be mentioned in negative feedback lesson)

This resource is for separates ONLY. *NOTE-using plant hormones-Higher tier only* AQA spec link: 5.4.1, 5.4.2 Relevant chapter: B11.9/10- AQA Biology third edition textbook-Page 176-179 *The new specification requires students to know the following; Plants produce hormones to coordinate and control growth and responses: to light, phototropism; and gravity, gravitropism (geotropism). Unequal distributions of auxin cause unequal growth rates in plant roots and shoots. Gibberellins are important in initiating seed germination. Ethene controls cell division and ripening of fruits. The mechanisms of how gibberellins and ethene work are not required. Students should be able to describe the effects of some plant hormones and the different ways people use them to control plant growth. Plant growth hormones are used in agriculture and horticulture. Auxins are used as: • as weed killers • as rooting powders • for promoting growth in tissue culture. Ethene is used in the food industry to control ripening of fruit during storage and transport. Gibberellins can be used to: • end seed dormancy • promote flowering • increase fruit size.

Making 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 and practice questions with answers on slides. NB: This resource is for separate science only AQA spec link: 4.3.2.1 Relevant chapter: B6 Preventing and treating diseases. AQA Biology third edition textbook-Page 106-107 Specification requires students to know the following; Students should be able to describe how monoclonal antibodies are produced. Monoclonal antibodies are produced from a single clone of cells. The antibodies are specific to one binding site on one protein antigen and so are able to target a specific chemical or specific cells in the body. They are produced by stimulating mouse lymphocytes to make a particular antibody. The lymphocytes are combined with a particular kind of tumour cell to make a cell called a hybridoma cell. The hybridoma cell can both divide and make the antibody. Single hybridoma cells are cloned to produce many identical cells that all produce the same antibody. A large amount of the antibody can be collected and purified.

Fossils and extinction lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability (trilogy/combined) class, although content can be adjusted to suit any ability.

NB: If you are unable to play videos a URL link can be found in the slide notes. AQA spec link: 4.6.3.5 Relevant chapter: B14 Genetics and evolution. AQA Biology trilogy edition textbook-Page 192-193 Students are required to know the following; Fossils are the ‘remains’ of organisms from millions of years ago, which are found in rocks. Fossils may be formed: • from parts of organisms that have not decayed because one or more of the conditions needed for decay are absent • when parts of the organism are replaced by minerals as they decay •as preserved traces of organisms, such as footprints, burrows and rootlet traces. Many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were have been mainly destroyed by geological activity. This is why scientists cannot be certain about how life began on Earth. WS 1.3 Appreciate why the fossil record is incomplete.
