The questions consist of exam-style questions on the four modules: Module 5: Equilibrium and Acid Reactions; Module 6: Acid / Base Reactions; Module 7: Organic Chemistry; Module 8: Applying Chemical Ideas . Therefore, depending on the conditions in those environments, the spread of the disease will vary. It may able to kill bacteria without causing the bacteria to develop antibiotic resistance O_O’. Contents. Guides. Also, more antibodies, specific to the pathogen, are produced in the secondary immune response than in the primary immune response. The first line of defence involves the physical and chemical barriers that helps to stop further entry, growth and reproduction of invading pathogens. Biology : past HSC questions, 2001-2014 by module, 2015-2018 by year, past 2019 HSC paper, three sample HSC exams Biology in focus : year 12 Brave New World : Year 11 Advanced English Module B : Critical study of literature, Student book. The 40 days allows an appropriate timeframe to allow symptoms of a disease to develop and sufficient time for handling the disease. These procedures prevent individuals having pathogens in their hood due to restaurant workers not following standardised procedures. Therefore, the drugs would be ineffective in controlling the disease. Suppose that we have B lymphocyte’s surface antibody successfully binding with an antigen. A 2014 case study that involved over using 24,000 patients’ data has revealed that: The incidence of influenza spreading from an infected family member to unaffected members are reduced in households. The potato plant’s example is same as the general-induced immunity and specific-induced immunity as we have examined in the above section. 20 HSC Biology Module 6: Genetic Change Practice Questions by Alex Gao The topic of Genetic Change is new to the HSC Biology syllabus and may feel like uncharted territory to some students, but that’s why it’s important you consolidate your knowledge with some practice questions! NOTE: Immunity will only occur if the vaccine has high efficacy (ability to produce desired result) or is highly effective against the pathogen. Therefore, the protection of intellectual property of the Aboriginal people is one that involves moral, ethical, legal (e.g. Year 12 HSC Biology Practice Questions: Module 5: Heredity Module 6: Genetic Change Module 7: Infectious Disease Module 8: Non-Infectious Disease and Disorders HSC Biology Module 1: Cells as the Basis of Life Question 1. Also any reproduction will occur inside the macrophage will be destroyed by lysosomes’ enzymes upon combination. Aboriginal and Torres Strait Islander Peoples consumed the Davidson plum as way to boost their body’s nutrient level which reduced their chance of having scurvy disease. Ensuring, monitoring and supply of clean water supply. Antigen-antigen complex provides a site for complement proteins to bind to which is able to attract phagocytes to bind to them and destroy the antigen. Zanamivir decreased the incidence of bronchitis while Oseltamivir did not. Food stored in refrigerators should be covered beforehand to prevent being contaminated with pathogens. The focus should also be ensuring that the quality of the toilet facilitates are being maintained and is up to appropriate standards in minimising the proliferation of pathogens and transmission of diseases via human faeces. However, fortunately, only approximately 5% are experiencing the symptoms. Changes to human habitation or behaviour – Actions to reduce human coming into contact with vector. In the case of animals, we will be using humans as an example and be looking into the three lines of defence that makes up our immune system. HSC Biology: Overview & Key Skills HSC Biology: FAQs We are an organization comprising of the most qualified, experienced and passionate HSC teachers/markers whose mission is to help students achieve the best in their final years of schooling. It is important to wash your hands before eating (e.g. What's new. Slip, Slop, Slap, Seek, Slide) & recommended products, How to individuals can detect early signs of skin cancer. Aboriginal Protocol: Smokebush is a plant used by Aboriginal people for their healing properties in increasing the rate of healing for cuts on their skin and other skin conditions. Animal Quarantine: Animals that cross the Australian border are required to be quarantined for forty days to ensure that the animal is not carrying pest or contracted with a disease prior to release. The adaptive immune response in humans involves three different biological molecules, these being: They play a role in the third line of defence in humans and have interactions with each other which we will explore now. For example, the Aboriginal People of Australia have acquired extension knowledge in using native Australian flora to treat diseases. Therefore, phagocytes will only operate or engulf matter that are foreign to the body. Combinations of these alleles result in three forms of the disease as shown in the following table. The first HSC examination for the new Biology Stage 6 syllabus will be held in 2019. This means that diseases, such as Influenza, can spread from one country to another at a massive scale.
