We discuss the process of photosynthesis and the different phases of photosynthesis and the inputs and outputs of each of the different phases.

We discuss the importance of photosynthesis in the food chain and we also take a closer look at the different factors that can have an effect on photosynthesis and how these factors affect the rate.

We take a look at the different experiments that can be done to investigate the rate of photosynthesis.

We take a look at the structure of the digestive system of humans and the different parts that make up the digestive system and the functions of each of the parts of the digestive system.

We take a look at how absorption takes place in the digestive system and the structures that are involved in the absorption form the digestive system. We also take a closer look at how the small intestine is adapted in order to efficiently absorb nutrient from the digestive tract.

We take a closer look at the control of blood sugar levels in humans and the hormones involved in the control of blood sugar levels.

We take a look at what a balanced diet is and the different nutrients that is needed in the diet in order for the body to function optimally.

We take a closer look at the process of cellular respiration and where it takes place. We discuss the various phases of cellular respiration and where each of the phases takes place as well as the requirements and products of each of the phases.

We take a look at the differences between aerobic and anaerobic respiration and we look at the different products that are formed in different types of organisms during the process of anaerobic respiration.

We discuss the various experiments that can be performed to investigate the requirements and products of cellular respiration.
