I did too until I stared at it for a minute! Points:
As she dives, there will be increased pressure
Results in lack of oxygen (cant exactly remember what it said in the box?) down there for too long which is possible as she is a deep sea diver
Also as she breaks surfaces there could be many bubbles - discomfort & ears popping.
Reduce this by swimming slowly up.

I wrote about all of that but also wrote about the double circulatory system saying the the oxygen enter from here etc but do u think I would get marks for that or is that wrong? Will I get marked down? :smile:

I said all of that,but I didn't say about the discomfort and ear popping, I said it could damage her heart or something..XD ah well

Haha it was the spur of the moment thing I remembered :tongue:

you'll be fine, sounds like you got majority of the points. It was quite weird..

Woah that's definitely detailed but you will never be marked down, no worries!

Nope. Insecticide doesn't cause algal blooms and will probably kill them as they aren't fertilisers/nitrates.

Because of how many people they screwed over in edexcel maths with putting questions on the last page (luckily I saw it) I always make sure I look on the back. To those who didn't do it..don't worry and I'm sure you'll pick up marks in other places! But now you know exam boards are stupid and do that..

I messed up the insectide question :frown:

I put about interdependence and how a reduced number of insects will mean less food for other organisms rather than bioaccumulation

Aw don't worry about it, grade boundaries will hopefully be low & looking at mark schemes makes me feel optimistic because they give you marks for the smallest things. Um overall I think I got 170 and hopefully a few more other marks..

If you didn't compare it, what did you do? As long as you included bits from the box and drew conclusions, it should be fine

You did amazing! :biggrin:

I got about 130 :/ I'm so disappointed because in all the past papers I was getting 80+ until that exam :/ I'm worried I won't even get an A now :/
