Welcome to the topic of balanced diet! Just like a car needs the right fuel to run smoothly, your body needs the right mix of nutrients to stay healthy and function properly. Understanding what makes up a balanced diet is…
We’ve already learned that photosynthesis is the vital process where plants convert light energy into chemical energy. Now, let’s delve deeper into what factors can speed up or slow down this process and what conditions are absolutely essential for it…
Welcome to the amazing process of photosynthesis! This is how green plants and some other organisms convert light energy into chemical energy in the form of glucose (sugar). Understanding photosynthesis is fundamental to biology as it is the primary way…
An ecosystem is a community of living organisms (biotic factors) interacting with their non-living environment (abiotic factors) in a specific area. Understanding ecosystems is crucial in biology as it helps us see how all living and non-living things are connected…
If you look around at any group of living things, whether it’s a bunch of students in your class or a group of dogs in a park, you’ll notice that they are not all exactly the same. These differences among…
Welcome to the fundamental unit of life – the cell! Understanding cell structure is crucial in biology as it lays the foundation for understanding how living organisms function. Both plant and animal cells share some common features but also have…
In the laboratory, we use a variety of precise tools to conduct experiments and unlock the secrets of the natural world. These tools are called laboratory apparatus. A solid understanding of each piece of apparatus, along with the correct way…
Welcome to the exciting world of science! In your O Level Combined Science studies, you will spend time in the laboratory conducting experiments. This is where you get to see scientific principles in action. However, the laboratory can also be…
A reversible reaction is a reaction that can proceed in either direction. One example of a reversible reaction is the reaction between nitrogen and hydrogen to form ammonia. N2(g) + 3H2(g) ⇌ 2NH3(g) A reversible reaction can be shown by the double…
