Campbell's Biology, 9e (Reece et al.) Chapter 6 A Tour of the Cell This chapter introduces the topics of microscopy and cell fractionation, followed by a review of the cell and the major organelles and structures of eukaryotic cells. A challenge with this chapter is to keep this data from simply being a list of parts. In addition to the structure and function of individual organelles, questions probe student understanding of the cell as a dynamic, interconnected system: the flow of membrane...

Interpret, calculate, and state the therapeutic range of the INR - INR = (patient PT ÷ mean lab PT)^ISI Therapeutic Range : 2.0-3.0 Calculate the MCV, MCH, MCHC given pertinent data - MCV (fL) = hematocrit × 10 ÷ RBCs MCH (pg) = hemoglobin × 10 ÷ RBCs MCHC (%) = hemoglobin × 100 ÷ hematocrit Identify each coagulation factor with its proper name - I : Fibrinogen II : Prothrombin III : Tissue factor IV : Ionic Calcium V : Labile factor VII : Stable factor VIII : Antihemo...

What is the MAIN role of membranes and what are the other roles? - ANSWER - COMPARTMENTALISATION -site of chemical reactions -cell signalling -cell adhesion How do cell membranes compartmentalise? - ANSWER Membranes are hydrophobic layers that separate different regions of substances dissolved in water. This hydrophobic layer acts as a barrier preventing the movement of hydrophilic molecules from one region to another. It keeps one compartment separate from another. What are the 3 examp...

A-Level Biology – OCR 100% VERIFIED ANSWERS Describe what is meant by residual volume and state the standard volume - CORRECT ANSWER-The volume of air that remains in the lungs even after forced expiration, i.e. the air that remains in the airways and alveoli (usually 1.5 dm3) Describe what is meant by tidal volume stating a typical figure - CORRECT ANSWER-Volume of air moved in and out with each breath at rest. A normal value would be 0.5 dm3. What is a light microscope used for?...
