It was the number who died divided by the number who suffered from malaria x 100 which gave me 0.(6 recurring). That's how I did it anyway.

No you're right. I accidently times by 100 again.

What was the answer to the question about brain sensitivity to alcohol and nicotine

Posted from TSR Mobile

Just that if the same part is used for both then the medicine should be able to prevent feelings of pleasure for both drugs

Or something along the lines of that

There was the question about the snails

Green land had strips and were light coloured - so camouflage

Wasn't the question asking how the appearance of woodland snails was beneficial?

Many people put lichens.
But, it was asking for ANIMAL

I said it was the same place in the brain so it is going to work the same and prevent pleasure from alcohol

What did people get for the question about all boys drinking and why was the hypothesis not valid??

none of the drinks were consumed by 100% of boys. so an amount could drink no drinks

I had 10 seconds at the end so I randomly wrote that Lichens detect moisture and that you can use a 'moisture indicator' to detect it...

Yeah, I'm pretty sure it said organism, and that does seem more like AQAs style to say organism, however it may have been animal, but I doubt it.

Do you think I would have got the mark if I said an independent company is a company that operates by itself and keeps its information private?
