BTEC APPLIED SCIENCE UNIT 2 BIOLOGY CHROMATOGRAPHY COMPLETED TO DISTINCTION 2023 Chromatography The term chromatography can be described as a technique used to separate the compounds within a mixture (or solutes), determined by the relative proportions of each solute distributed between a moving fluid stream, which is called the mobile phase, as well as a stationary phase which could be potentially contiguous. The stationary phase might be in the form of a solid or a liquid whereas duri...

The krebs cycle occurs: inside the mitochondria the series of membrane bound proteins and cytochromes that couple ATP production with the movement of electrons in the mitochondrial membranes is called Electron transport system cellular respiration in the absence of molecular oxygen is called anaerobic cellular respiration in the presence of molecular oxygen is called aerobic most fish and many invertebrates have this type of gas exchange system gills the organism the we expect to ...

1. What is a mixture? - Ans .Two or more elements not chemically bonded 2. What is the difference between a compound and a mixture? - Ans .Compounds have a fixed composition whereas mixtures do not. Mixtures are not chemically bonded but compounds are. 3. Describe the process of filtration - Ans .Pour the mixture onto the filter paper, the liquid simply passes through the filter paper into the flask. The insoluble solid cannot pass through and so it stays on the paper 4. Describe the pr...
