This section introduces the concept of health and its relationship to communicable and non-communicable diseases.
Definition: Health is a state of physical and mental wellbeing, influenced by various factors including diet, stress, and life situations.
Communicable diseases gcse AQA curriculum emphasizes that both communicable and non-communicable diseases can significantly impact physical and mental health. Understanding these concepts is crucial for students studying preventing and treating disease AQA topics.
Highlight: Diseases, whether communicable or non-communicable, are major causes of ill health and can profoundly affect both mental and physical wellbeing.
This page delves into the causes of communicable diseases, focusing on various types of pathogens.
Vocabulary: Pathogens are microorganisms that cause diseases, including bacteria, viruses, fungi, and protists.
Bacteria gcse biology topics often cover how these microorganisms reproduce rapidly inside the body, with bacteria producing toxins and viruses causing cell damage.
Example: Pathogens can spread through direct contact, air, or water, making understanding transmission methods crucial for prevention.
This section discusses laboratory techniques for growing bacteria, essential for studying bacterial diseases gcse AQA topics.
Highlight: Uncontaminated cultures of microorganisms are grown using sterilized Petri dishes and agar, with strict protocols to prevent contamination.
Growing bacteria in petri dishes experiment procedures include:
Definition: Incubation is the process of maintaining optimal conditions for bacterial growth.
This page focuses on bacterial reproduction and methods to prevent their growth, crucial for understanding preventing and treating disease gcse topics.
Example: Bacteria can multiply by simple cell division as frequently as every 20 minutes under optimal conditions.
Growing bacteria experiment techniques often involve: • Investigating the effects of disinfectants and antibiotics on bacterial growth • Using agar plates to observe and measure bacterial colony growth • Calculating cross-sectional areas of bacterial colonies
This section covers various methods to prevent the spread of communicable diseases, a key aspect of preventing and treating disease biology.
Highlight: Simple hygiene measures, isolation of infected individuals, and vaccination are effective methods for preventing disease spread.
The page also introduces viral diseases, focusing on measles and HIV:
• Measles: Spread by droplet infection, causes fever and rash, preventable by vaccination • HIV: Initially causes flu-like symptoms, attacks immune cells, and can lead to AIDS if untreated
Vocabulary: AIDS is the late stage of HIV infection when the immune system is severely compromised.
This page continues the discussion on viral diseases, focusing on HIV and Tobacco Mosaic Virus .
Highlight: HIV is spread through sexual contact or exchange of body fluids, such as when drug users share needles.
Tobacco Mosaic Virus: • Spread by contact and vectors • Damages leaves and reduces photosynthesis • No treatment available • Prevention through field hygiene and pest control
Understanding these viral diseases is crucial for students studying bacterial diseases gcse AQA and related topics.
This section covers specific bacterial diseases, their symptoms, and prevention methods, essential for bacterial diseases gcse biology studies.
Salmonella: • Spread through undercooked food and poor hygiene • Symptoms include diarrhea, abdominal cramps, fever, and vomiting • In the UK, poultry are vaccinated to control disease spread
Gonorrhoea: • Sexually transmitted disease • Symptoms include discharge from penis/vagina and pain during urination • Treatment involves antibiotics, but many strains are becoming resistant
Highlight: Using condoms and limiting sexual partners helps prevent the spread of sexually transmitted bacterial diseases.
This page explores diseases caused by fungi and protists, expanding on the 15 diseases caused by bacteria and other microorganisms covered in the curriculum.
Rose Black Spot: • Fungal disease spread by wind and water • Damages leaves, affecting photosynthesis and growth • Controlled by removing infected leaves and chemical sprays
Malaria: • Caused by a parasitic protist, spread by female mosquitos • Damages blood and liver cells, causes fevers and shaking • Prevention includes vector control and using mosquito nets
Vocabulary: Vectors are organisms that transmit pathogens between hosts.
This section discusses the body's defense mechanisms against pathogens, crucial for understanding preventing and treating disease biology.
Highlight: The body has several lines of defense against pathogens, including physical barriers and the immune system.
Defense mechanisms include: • Skin • Mucus in the trachea and bronchi • Acid in the stomach • White blood cells that ingest pathogens and produce antibodies and antitoxins
Understanding these defense mechanisms is essential for students studying why is it difficult to develop drugs that kill viruses gcse topics.
This final page covers plant diseases, their detection, and management, rounding out the comprehensive study of communicable diseases.
Highlight: Plants can be infected by a range of viral, bacterial, and fungal pathogens, leading to various symptoms and conditions.
Detection methods for plant diseases include: • Visual inspection • Reference to gardening manuals • Laboratory tests, some involving monoclonal antibodies
Understanding plant diseases complements the study of human and animal diseases, providing a holistic view of communicable diseases examples across different organisms.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
