A cell has the following properties: ECa = +100 mV ENa = +50 mV EK = -100 mV ECl = -60 mV There are active transporters for the ions, but the active transporters are electroneutral (they do not generate a Vm). If the cell is permeable to both Ca2+ and K+, then the Vm is [ Select ] . If the cell is permeable to both Ca2+ and Na+, then the Vm is [ Select ] . If the cell is permeable ONLY to Cl-, then Vm is [ Select ] . The cell is initially permeable only to Ca2+, but then Na+ channels are opened. After the Na+ channel opens, the Vm will [ Select ] .

Use the following set of data and grid to plot the cumulative % mass vs passing size (µm), and hence estimate the F80. Use Excel to plot your graph and copy and paste it in below: Sieve range (µm) +3350 -3350+2000 -2000 +800 -800 +500 -500 +180 -180 +63 -63 Total mass (g) Mass retained (g) 0 (insert first 3 digits of student ID} 247 62 51 35 43 First 3 digits = Total mass = F80 from graph = QUESTION B6 (5 marks) There are 7 broad categories of "biomass". Fill in the Table with ONE example for each category: Category Animal products Example manure Using your example given for the category "energy crops", briefly state TWO key challenges in using it as a fuel source to produce electricity.
