1. For the malaria question I got 6.7% ????
2. (Original post by Nik123Efimov)
0.66666666667%. Or just 0.6%
I did the correct calculation apart from multiplying by 100. How many marks am I likely to get out of the 2, 1 or 0?

No it was definitely faster per second

Travelling to the brain was 3cm per millisecond. Travelling to the CNS was 1.6cm per millisecond. Therefore, the brain is faster, as it travels 2.4cm further in a millisecond than the CNS.

Is there even a question to ask you which one is faster?
The question below the calculation is asking you why is the brain faster.
It is because of less synapse
Whoops I wrote how relay neurones are faster goddamnit haha

5. [
i spoke about how rats show that there is sewage effluent as pollution .. would i get a mark?

i also got 66.6% for the mosquito questions, however i was shocked when i was told 0.6reccurring, I might have multiplied it by 100 twice i guess. Oh well.
6. Anyone know that feeling when the paper is really hard except for that 6 marker but your the only guy that misreads the question and writes about homeostasis ? No? Ah guess its just me

Actually that makes sense. I think you're right.

That question was confusing...
10. what did people put for the malaria question about sentence 1 not being true in the article
11. (Original post by 0lut0)
Was the horse question about mutation or variation?

Mutations
12. What did everyone put for the animal indicator? I put lichen and that it determines level of sulphur dioxide in the air but apparently a lichen is a fungus and not an animal... Would I still get either of the marks?

Amazing

How did it go for you?
Surprisingly quite well thanks!!
Today has been a good exam day, French and biology where very nice

What did people get for the question about all boys drinking and why was the hypothesis not valid??
I said because it was only tested on 100 people so not valid to say every boy drinks??

omg that makes sense, I wrote the neurones were longer so there would be less diffusion time

Most likely 1
19. (Original post by lunaticash19995)
Are you sure?
Yeah it was 80cm over 50s to get 1.6cm/milliseconds compared to 12cm over 4ms to get 3cm/ms
20. Question about temp senser instead of thermoneter was its more accurate right ?
