    for the question about whats in the testes and what does it do do you just write that its testosterone and promotes male secondary sexual characteristics eg deepening of voice?
    I put that, and that it stimulates the production of sperm...I think

    Me too. Like all that revision on osmoregulation, the human body and plants and they gave us secchi disks and garlic? I feel like the exam had very little to do with biology and more to do with common sense and creating experiments. This isn't suppose to be an IQ exam..

    i put something similar, about how it's a more invasive procedure etc. Because they're inside the body, while testes hang outside so the sperm ducts are more accessible...

    what did you write for the one with the cross section of the leaf and all the section describe how they participate in photosynthesis things...???
    layer A was like the upper epidermis and waxy cuticle; you had to say it helps by preventing entry of disease-causing microorganisms interfering with the process

    layer B was like the palisade cells it was like they contain lots of chloroplasts so they can absorb light energy

    layer C was like the spongy cells i think that was about how they were loosely-packed cells with air spaces to absorb carbon dioxide to diffuse into the leaf for the process of photosynthesis and allow it to get to the palisade layer

    struture D was like the stomata and guard cells so they are the pores or openings which allow the CO2 to be diffused inside for the process and go to the spongy cells and O2 to diffuse outside as a waste gas

    Well, you can create a new thread (post button at top in green bar) but there is the whole 'study help' forum where people just post threads when they get stuck and you can reply to their threads with help and stuff.

    You can't create a whole forum though - that lies in the hand of the mods.

    It was specifically written that draw a bar chart and line graph would obviously get a 0
    normally get half marks for doing the wrong chart, make sure you check mark schemes Name:  Screen Shot 2015-05-12 at 19.11.29.png

    The mosquitoes and garlic was totally messed up.

    The marker is going to worry about our generation when they see all the sadistic methods we came up with for that experiment. Too bad.

    Yeah, I'm genuinely worrying that I didn't lock my people in a room with mosquitoes, I just let them do their own thing - never thought THAT'd be something I worried about!!

    It was because if the stomata were in the bottom then water vapor would not be able to escape because of the concentration gradient. In order for water to move out of the stomata it has to be from an area of high concentration to an are of low concentration which would not be possible if it is moving into water!
