This Biology exam paper, "Bio 2 NW 2026.pdf", is divided into two sections. Section A requires answering all three questions and covers topics such as:

• Comparative Biology: Features of birds and mammals, adaptations of fish, and the economic importance of insects.
• Human Physiology: Functions of reproductive organs (vagina, breast, testis), definitions of excretion and homeostasis, adaptations of mammalian skin, the role of the kidney in water regulation, and the functions of insulin and glucagon in blood sugar control.
• Ecology and Conservation: Definitions of ecosystem and conservation, differentiation between food chains and food webs, and methods to reduce species extinction.

Section B is partially visible and asks for two questions to be answered, with one sub-part asking about the difference between photosynthesis and respiration.
