Same, that question was quite tricky though, I had to use the knowledge of the radioactive decrease of a radioisotope to get that.


I got 2 hours ..I think I mucked up the transportation question :/

What did everyone say for source of error for the pitfall trap?


I said bugs could walk around it :colondollar: Lol

Was that 2 marks or just 1?

I said too high above soil level or may not be camouflaged. What did you put?

I said inappropriate size of trap selected

How did everyone think it went. I feel like I did good though I have lost a mark in a calculation.

Am I the only one that found it hard!? I hate biology! I was hoping I could scrape a C but the boundaries will probably be going up :frown:


I found it sooo hard. I was predicted an A and got an A in my prelim but I don't think I'm going to get that.

The first thing I did when I got home was eat junk food and get into my pyjamas.

Now I'm going to watch Netflix and sulk.

It went so bad :s-smilie:

Was the nat 5 bio this year very hard?

.. I heard people complaining about it on the way out of the exam hall while I was doing my higher

I think it was why the rat something plant decreased, it was after calculating the average decrease of the plant


I don't remember that question. How many marks was it??

I think it was 1, and it was why a plant was decreasing and the meadow grass was increasing

For question 3 on section A I got D but I wasn't sure and for question 20 I got C
do you have a copy of the paper you could upload?

I think for question 3 the reason why it was b was due to the fact the really bottom of the root was a 0% cell division but after that it was 50% and the it continued to drop directly proportionally by 20%, so that's why it took on the shape of a curve as it starts from zero increases then decreases. But for 20 I was a bit stuck 😬

Yeah 3 was B. For 20 I found it quite easy. If there're no fresh water shrimps then the algae was increase as there's nothing to eat them and the dragon fly nymph would decrease as there jo good for them if u get that??

Do you know if can remember that question why the ratword plant was decreasing, it was after calculating the average decrease and before the pitfall trap error question
