IB Biology Topic 1: Cell Biology Questions and Answers Already Passed What does cell theory state? That cells are the smallest possible unit of life and that living organisms are made up of cells. What are unicellular organisms? Give two examples Unicellular organisms are organisms with only one cell, such as Paramecium and Chlamydomonas. In unicellular organisms the one cell carries out all of the functions of life. Why are large organisms multicellular? Because of surface area to ...

IB Biology HL Exam Review Latest Version Already Graded A Outline the cell theory. Living organisms are composed of cells. Cells are the smallest unit of life. Cells come from pre-existing cells. Discuss the evidence for the cell theory. The nature of scientific theories could be introduced here: the accumulation of evidence that allows a hypothesis to become a theory; whether a theory should be abandoned when there is evidence that it does not offer a full explanation; and what evid...

AC-HPAT Biology 2024 Guide with complete solution Graded A+ 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 devi...
