Page 2: Immunity Process and Antibiotic Resistance

This section delves into the historical context of immunology and explains the detailed process of immune response, particularly relevant for CCEA double award biology unit 2 questions.

Definition: Antibiotic resistance occurs when bacteria develop the ability to survive treatments that previously would have killed them.

Example: The page presents James's case study to illustrate how immunity develops in response to bacterial infection.

Highlight: MRSA is highlighted as a significant example of antibiotic-resistant bacteria, particularly problematic in hospital settings.

Quote: "Edward Jenner was a doctor. He found that if someone had suffered from cowpox, they would be immune from catching smallpox."

Page 3: Non-Communicable Diseases

The final page covers non-communicable diseases, focusing on heart attacks, strokes, and cancer, essential topics in the CCEA double award science biology curriculum.

Definition: Cancer occurs when cells divide uncontrollably, forming tumors that may be detected under the skin.

Example: Angioplasty is described as a treatment for blocked arteries, using stents and balloons to restore blood flow.

Highlight: Lifestyle factors such as alcohol consumption, smoking, lack of exercise, and UV exposure significantly impact health outcomes.

Vocabulary: Benign and malignant are terms used to classify different types of tumors based on their characteristics and behavior.

Page 1: Microorganisms and Immunity

This page explores the fundamental concepts of microorganisms and immunity in the CCEA GCSE double award science curriculum. It details various types of microorganisms, their transmission methods, and prevention strategies.

Definition: Immunity is the body's ability to protect itself from infection, occurring either actively through antibody production or passively through receiving ready-made antibodies.

Example: The spread of microorganisms can occur through direct contact, sexual transmission, food contamination, droplet infection, and aerosol transmission.

Vocabulary: Antigens are markers on cell surfaces that help identify foreign substances in the body.

Highlight: White blood cells are crucial components of the immune system, with two distinct types working together to fight infection.

Quote: "Some micro-organisms can be harmful. Your body's immune system fights these micro-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.

Samantha Klich

Android user

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.

Best app on earth! no words because it’s too good

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.

David K

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

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.
