air) too. If any higher temperature was used, it would destroy the wine/beer which is undesirable. This module better prepares you to understand the causes and effects, and strategies put in place to limit the spread of infection. Also, these Pili and adhesion proteins can attach to host cells as we have explored in the previous section. or. They are not made up of cells but rather they have a protein coat containing genetic information in the form of DNA or RNA. Unlike virus, bacteria cannot enter via receptor-meditate endocytosis due to their significantly larger size. They undergo asexual reproduction via the binary fission process. The powdery mildew plant disease is caused by a fungus and can infect a plant (and cause plant disease) using the mechanism described above. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Therefore, in such scenario, the vector will be acting as the mode of transmission of pathogen. apply Put to use in a particular situation.

During the time hookworm remains in the body and intestines, it can cause many disease such as by penetrating intestinal walls. Step 4: Dip your sterilised inoculating loop into the food sample in one of your test tube and wipe the food gently on the surface of your agar. Adaptations for Air Transmission via water droplets: There are pathogens that can survive the acidic environment of stomach by secreting enzymes that enable it to convert urea in the blood into ammonia. Then, an unaffected species eats the infected food. Inquiry question: How does mutation introduce new alleles into a population? On the topic of food, food is an important part of understanding the transmission of pathogens. Course Description. one country to another). HSC | Biology < Back to HSC at Belmont Christian College. Here is a great overview on how it can enter the blood, and some features of the bacteria! The same rod-shaped microbes were observed across other affected organs by Tuberculosis. From his experiments with vaccines, Pasteur established the Principle of Immunity of using vaccines to provide immunity against diseases as well as the Germ Theory of Disease where germs (which we call pathogens today) are responsible for causing disease. Current visitors New profile posts Search profile posts. Bacteria have a circular thread of double helix DNA which is in the form of a single, large chromosome in cytoplasm. The syllabus and related assessment materials are available on the syllabus page of the NESA website. Consumers experience an increase in price, lowering affordability.

Biology: Module 7. Simplify your notes so that you don’t get confused. 1. To do this, water (must be present on the plant’s surface (e.g. Get our latest COVID-19 advice . bacteria) or agent (e.g. Many protozoans are live in water and they are mobile in water due to the presence of a ‘tail’ called flagellum. Step 3: Transfer small quantities of three different food sample into three test tubes with 2mL of distilled water and gently mash up the food samples. Koch was interested in studying Tuberculosis because it was a highly prominently disease during the time. Bacteria basically exist ‘everywhere’ that we go and many are actually beneficial to us. Spell. Sometimes, an organism acting as vector must be present to carry the pathogen (e.g. While we are at it, we might as well introduce the definition of non-infectious disease as we will be examining it the upcoming weeks. Pasteur said that was the presence of the presence of lactic acid bacteria microbes that contributed to the spoilage of wine. The fungus’ hypha is able to penetrate skin pores or hair follicles in sheeps. This was put on a public trial when a famous veterinarian disagree with Pasteur about his results, mentioning that he yielded different set of results to Pasteur. In order for this happen, there must continuous monitoring of the strain of virus that is responsible for causing the Equine Influenza Disease. Module 6: Genetic Change. However, to describe other mechanisms of food and water borne pathogens, make sure to use another example like, The work of Robert Koch and Louis Pasteur was pivotal to understanding transmission, of infectious diseases. Guide to HSC Biology Module 7: Infectious Disease; Guide to HSC Biology Module 8: Non-infectious Disease and Disorders; Enter to win! Search. This infection increases in scale, the cambium tissue consisting of the xylem and phloem will die which can result in the eventual death of the entire plant including fruits, if infection is not cured. Hence, they are not readily denatured even under abnormal conditions. For virus to affect a plant, usually a vector (e.g. Pathogen causing the Equine Influenza: Equine Influenza Virus (a strain of Influenza Type A Virus), The virus can spread between horses via nasal discharges that are produced. This can be ordering affected employees to remain at home and not commute to work. Host – Any organism that carries another organism (e.g. If you need a quick recap of these topics, make sure you check out HSC Together which has FREE videos on every single HSC Biology syllabus dot point so that you can effectively consolidate your knowledge!

Based on this information, Koch theorised that the pathogen that caused tuberculosis was a bacterium. … Biology module 5 and 6 guide (docx 113.95 KB) Module 5 reproduction unit of work (docx 48.97 KB) Genetic variation and human evolution resource (pdf 142.96 KB) Module 7 guide (docx 98.27 KB) Module 7 infectious disease assessment task (docx 49.76 KB) Module 7 … HSC | Biology < Back to HSC at Belmont Christian College. Step 2: Sterilise your inoculating loop by heating it in the flame of bunsen burner. 3. Imagine that your immune system is weakened and cannot fight off baddies, or you have a deep skin wound. Biology: 91 - (Ranking 4th) Module 5: Heredity Module 6: Genetic Change Module 7: Infectious Disease Module 8: Non-Infectious Disease & Disorders. Non-Infectious Disease – A disease that is NOT caused by a pathogen and is unable to be passed from one organism to another. A favourable environment for pathogen to reproduce or replicate. 1300 677 336; SIGN IN; 0; OUR PROGRAMS. Fungi have acquired adaptation in developing cell wall and capsule that allow some of them to survive and continue to produce spores when engulfed by macrophages. The common groups are spherical, rod, spiral, comma or oval shape. The bacteria pathogen, however, is not able to do this. Biology; Year 12; Causes and Transmission Of Infectious Diseases Module 7 Infectious Disease Inquiry Questions 1 ; Page 1/21. In the case of fungi, the pathogen were able to breakthrough the epidermal cells of the plant directly. From this, Pasteur stated that both there are two types fermentation reaction in the production wine and beer, each required the presence of microbes. Module 5 - Heredity. HSC Biology: FAQs. In non-endocytotic pathway, after binding, the virus fuses with the cell membrane and only the genetic information of the virus is passed through to the cell membrane and into the cytoplasm. 21 Pages HSC - Higher School Certificate Year 12 Complete Study Notes Year Uploaded: 2019. 4th Factor (for transmission between affected and unaffected individuals): In order to transmit the disease from one affected organism to another, a mode of transmission of the pathogen is required. Module 5 - Heredity. Normal bacteria on your skin is normal, but sometimes these bugs can take advantage of your sickness. This is because by heating the wine, some of the non-pathogenic (non-infectious) micro-organisms are also eliminated from the wine. Able to survive in placenta and transmit transmit disease when organism consume placenta. Designed for educational purposes. handrail). NOTE: Each neuron in the brain is capable of forming thousands of synpases to connect with thousands of other neurons. 3. It is important to note that a virus cannot reproduce by itself but must rely on a host cell for replication. Comparatively, the flask without the “S” shape had microbial colonies formed on the surface of broth. Mosquito bite injecting pathogen into host organism). HSC Biology exam tips. Adaptations for Vector-assisted transmission: Pathogen’s structural integrity and capacity to act as an infectious organism or agent are not affected when absorbed by or bound to vector. Some of the pathogens reproduce sexually to produce male and female gametocytes which a second mosquito will uptake when the affected human is bit. When infected horses cough, they secrete nasal discharges containing the virus which can be inhaled by unaffected horses. University Guide TAFE Guide Study Tips. … The new Biology syllabus has been developed using the established NSW Education Standards Authority (NESA) syllabus development process. Direct contact between affected and unaffected sheeps can also result in the transfer of spores. Intended audience. Now that we know what pathogens are and how they cause disease, we need to know how we can stop the spread. Upon successful binding, the virus is able to transported through the membrane via the receptor mediated endocytosis or via a non-endocytotic pathway. Heredity study session. The rod-shaped microbes may have been produced as a result of the disease rather than the cause of the Tuberculosis. Exception: Inherited Disease is often classified as a non-infectious disease as it can be passed from one organism to another.
