    A Level Biology Paper 52 3rd May 2017

    I wrote a similar answer that to "provide daphnia a suitable, soft place to rest so it does not get hurt/damaged when placing it on the slide"

    Malaria one was separate. That one was a simple q. Yeah and there was no q. on TB though.

    not lining of airways.. i don't remember the exact question but it was about alveoli and the answer (which i was pretty sure of at the time i was answering) was about elastase breaking down elastin in alveolar walls.

    in the last question the base sequences in each unshaded box were same right? also magnification i think was x500 right?

    in the first part it was "identify" the organic compound so in the boxes we could write structural/displayed or partial displayed formulas. In the next part it was structural formula and only lines were given so structural were a must. And in the last IR part, "names".

    another thing, i wrote is that leave the daphnia in the caffeine solution for 10 minutes, before observing under microscope. The reason for that which of course i didn't write was that caffeine takes time to affect our system. For e.g in humans it takes like 30 minutes to properly come in effect...

    Critical value i think number 9. our value was higher so relationship was not proven. more "plant" in higher mean january temperature as the plant is better adapted to that temperature and the temperature is closer to the optimum temperature for the enzymes in the plant so the plant survives...

    oh i remember now! it was "daphnia" i wrote that instead of crustacean.

    How was May/June 2017 Biology P52?

    I wrote that the volume of the caffeine solution should not be "few drops" it should be exactly 10 drops for each, the drops added using same type of dropper. Apply normal pressure on dropper each time to ensure each drop is of approx. equal volume. (My logic behind this was that if volume is...

    Guys was there another name for the "crustacean" written in the first question? idk if i used "crustacean".

    A Level Biology Paper 52 3rd May 2017

    this was a 2 mark question i wrote use 100cm3 capacity burrette 5 times (i've seen such a statement in chemistry) to measure out 500cm3 water into a beaker. Add 1, 50mg caffeine pill into this and stir to make 500cm3 of 100mgdm-3 caffeine solution. I am pretty confident this can get me the 2...

    if i considered population as 50 (as stated in q) and not read from graph... can i get 2 marks for calculating, and using the formula all correctly but for 50 instead of 60... :(

    I don't think it is necessary. So if i wrote it is a tissue, Described its "specific" function (transporting blood to heart via coronary artery, and to rest of the body except lungs) and wrote about its structure for e.g elastic fibers to withstand high pressure can i get at least 2 marks?

    oh the equation. Am i correct? triglycerides+water------->glycerol + 3 fatty acids. also in the first table...photosynthesis, Smooth ER, mitochindira, Rough ER.

    so you are saying even arteries are organs because they have multiple types of tissues? nope. It was a two sided question for sure. The heart is an organ. Never will you ever find aorta when you learn about human organ system.

    length of what? i wrote about volume of caffeine solution added should be constant. yes last part q.1 same as yours spearman rank yes 0.88. low risk experiment. Handle the (sea animal don't remember name) with care wear gloves if allergic to it. in the 6 mark Q i think 2 marks for dilution...

    How was Biology Paper 22 MAY/JUNE 2017?

    I think the question could be answered in both ways... a tissue or organ. i wrote a tissue. And then brief description of the structure of aorta and "specific" function that was to transport blood to all parts of the body except lungs, even to the organ, heart via coronary artery. I might be...

    I think it was okay. A couple of tough questions were there. Expected gt I think around 43.. so how was it for you?
