Course description
This A Level Biology course includes will allow you to explore DNA and biodiversity, photosynthesis and respiration, cells and organisms. Understanding the physical structure of our bodies, how animals and organisms work and how we have evolved is very important, especially in producing cures and treatments for many different diseases.
