Only N2O is trapped in ice. So2 + NOx cannot because they are soluble in water and are hence extricated as acid rain.

Lol sorry about that. Thanks for the additional info!

The student may perceive ethanol to be entirely carbon neutral due to the fact that ethanol is a renewable source, that can be produced from the fermentation of cellulose (which can be derived from biomass i.e plant matter, via photosynthesis): 6CO2 + 6H2O + UV light > C6H12O6 + 6O2...

Geiger muller tubes are based on the ionising properties of radiation, hence most effective for measuring alpha + beta radiation. So essentially the radiation enters the tube, and collides with gas molecules within (predominantly argon is used), and ionises the gas i.e removes an electron. The...

Same but just think about it - you only have a certain period of time left until it'll all be over - make the best use of your time! That's what helps me get through it :)

What will 62/70 align to?

Same - easy except Question 16 (c) - I didn't get that out but the rest was great!

Thank you! :)

If 20 is B) Characteristics are not transmitted to successive generations and all your other ones are correct, then I got 100%!

Re: General Thoughts: Biology Can anyone post multiple choice answers?

SO GOOD OMG THAT WAS AMAZING - I feel really good about it!

Most transgenics species are clones and cloning is a reproductive technology, so yes. But I don't think it is alone. It's fine to talk about it if you relate the fact that your transgenics species are produced as clones. for eg. Bt cotton is a transgenics species (with the gene that codes for...

Look just move on. Stewing over it is a waste of time. It's only one subject so focus on your others
