OCR A LEVEL ORGANIC CHEMISTRY YEAR 12 WITH VERIFIED QUESTIONS AND ANSWERS What is the melting and boiling points of alkanes like? - ANSWER--as chain length increases so does the strength of the intermolecular forces as there is greater surface area for contact between molecules and hence stronger london forces and therefore the melting/boiling points are highr for longer chain. What is a structura/chain isomer? - ANSWER--Same molecular formula but a different structural formula Wh...

AQA A Level Biology: Year 1 -Mass Transport In Animals Why is mass transport important ? of substances across cell membranes It maintains the diffusion gradients which allow the exchange What the adaptations of red blood cells? 1. Small/thin - pass through the narrow capillaries Similar diameter to capillary lumen - short diffusio path 3. Biconcave so they have a large SA:V- haemoglobin is close to the surface 4. No organelles so they can carry more haemoglobin Describe the ...

The document consists of summarised notes on the mass transport section of unit 3 in AQA A-level biology. It includes every subtopic that consists of the mass transport section with diagrams to help learn. Words highlighted in yellow are the headings.
