Yeah 80 will definitely get the 90 but probably would be 91-92If you are talking about band 6, should aim for 80s (last year says it all to all science)

Or get 90 to guarantee it. You never know.Yeah 80 will definitely get the 90 but probably would be 91-92
Unlikely cut off will be that high.Or get 90 to guarantee it. You never know.
.With easy papers come anal marking.
Advantages - More likely undergoes complete combustion (less toxic emission such as CO and C, insert equations), Renewable (made from biomass duh), carbon neutral (Input = output), theres a lot.Unlikely cut off will be that high.
Okay let's get back to asking each other questions so we can critique them and learn from them. I'll start off -
Evaluate ethanol as an alternative source of fuel. - 5 marks.
Loving that judgementAdvantages - More likely undergoes complete combustion (less toxic emission such as CO and C, insert equations), Renewable (made from biomass duh), carbon neutral (Input = output), theres a lot.
Disadvantages - Expensive to produce (fermentation and distillation is rip, insert equations), requires arable land (stinky and wth we don't enough land anyway, can lead to soil erosion), lower heat of combustion (petrol is still better), energy modifications (not really today), blah blah
Judgement - For now, piss off ethanol.
what
But it's true, ethanol is not economically viable and also makes the focus area pretty boring tbh.Loving that judgement
So no one pees in thereExplain why there is a need for constant monitoring of water supplies in catchments.
someone please write this in an exam lolSo no one pees in there
Why Spectrometry important to the environmentHAHAH okay you guys ask questions so 14ers can answer

Yeah it bioaccumulates in organisms once consumed and makes it way up the food chain causing harm. EtcAlso heavy metals (lead and all that)
