IB Biology Topic 1: Cell Biology Latest Update Graded A Cell theory The theory that cells form the fundamental structural and functional units of all living organisms. Differentiation The expression of a particular gene(s) and not others in order for cell specialisation. Emergent properties The idea that the sum of an organism is more than the parts interacting and combining. Living things become more complex as they move (from individual cells to organ systems). Multicellular...

AC-HPAT Biology Questions and Answers 100% Pass Pancreas and Type 1 diabetes The pancreas is the organ that produces insulin, and it plays a major role in regulating blood glucose levels. Type 1 diabetes occurs when the pancreas does not make enough or any insulin. How does insulin work in diabetes? Insulin pumps are small, computerized devices that mimic the way the human pancreas works by delivering small doses of short acting insulin continuously (basal rate). The device also is ...
