    Believe it or not, i forgot what i wrote, what did you write??
    I'm pretty sure I got it wrong but my answer was "Because they have large teeth, the food molecules are too small and move to fast thus amylase will have no effect" Sounds stupid I know :P But from what I've heard, the correct answer is that amylase is not required because lion's don't eat many carbohydrates thus the amylase is useless. hmmm

    Woah, i definitely didn't write that, that's not always true tbh , i would say that's somewhat wrong. And contextual knowledge wont be required in an exam , only your application of the biology syllybus, so i highly doubt that's right.

    I talked about it being a carnivore... which now seems extremely stupid

    For the amylase question I wrote that lions are carnivores - which means they don't eat many carbohydrates. This would therefore make amylase in the mouth useless as the lions would require a different enzyme such as pepsin or protease to break down the meat.
    Do you guys have any predictions for paper 2? Getting a bit worried.

    yes can anyone provide the topics tested in paper 1. The topics that are not tested should be the focal point of our revision

    The answer to the amylase questio was that meat is protein and and therefore amylasye enzyme does not act on it.It only acts on starch.

    So I am going to list the ones I think did not come up on that test:
    Breathing and Gas exchange
    Genetic modification
    Coordination in Animals/Plants
    Transpiration
    Digestion system(Kinda but not a lot)


    Anyone want to add onto the list?

    Finished paper 2 thought it was ok but the 4 marker on germinating seeds threw me off a bit.

    I measured energy content in the same way you do it with food so change in temeprature times mass of water times 4.2 or whatever

    My answers may not be 100% correct but it matched with some of my class mates, of course please tell me the ones I got wrong and help expand my answers
    These aren't in order... (I may be missing some)
    1a) What is Digestion?
    Ans: Digestion is the breakdown of large insoluble food molecules into smaller soluble molecules so that they can be absorbed.
    1b) What control can be used when testing blood glucose levels after crushed pancreas is injected to the dogs (IDK the exact question word for word, but it's similar)
    Ans: Do not inject crushed pancreas to some of the dogs without a pancreas to observe the difference. (Something Along Those Lines)
    1ci) Stimulus
    Ans: Level of Glucose
    1cii) Receptor
    Ans: Pancreas (not sure)
    1cii) Effector
    Ans: Pancreas (not sure)
    1ciii) I forgot what the question asked
    Ans: -
    1d) What blood vessel carried the hormones (IDK question word for word)
    Ans: Hepatic Artery
    2ai) Water Cycle
    A-Evaporation
    B-Transpiration
    C-Precipitation
    2b) Explain how deforestation can affect water cycle (IDK I'm probably wrong, byt most of my classmates wrote something similar)
    Ans: Cutting down of trees, reduces transpiration, less cloud formation occurs resulting in reduced amounts of rainfall, this can cause not much run off to flow into rivers which can contribute to drought as rivers dry up because evaporated water isn't replaced by the runoff from mountains.
    2c) Explain how carbon cycle is affected by deforestation? (IDK the question)
    Ans: Burning trees release carbon which is a green house gas that contributes to green house effect and can bring about global warming, Fewer trees, less decomposition, CO2 not removed from air as less photosynthesis occurs due to lack of trees
    3a) Energy Content of Seed Question
    Ans: (Copied from Internet)
    a Use the measuring cylinder to measure volume of water
    b Measure the temperature of the water with the thermometer. Record the temperature in a suitable results table.

    c Find mass of seed. Record the mass in the table.

    d Impale the seed with needle/Use tongs to hold seed.

    e Light the Bunsen burner and hold the seed in the flame until it catches alight.

    f As soon as the food is alight, put it under the boiling tube of water as shown. Try to make sure that as much of the heat from the burning seed as possible is transferred to the water. Do this by keeping the flame under the tube.

    g Hold the seed in place until the seed has burnt completely.

    h As soon as the seed has burned away completely and the flame has gone out, measure the temperature of the water again. Before measuring, stir the water carefully with the thermometer and note down the highest temperature reached in the results table.

    i Repeat the procedure several times, reject anomalous values and average it out.

    j Calculate the rise in temperature each time.

    k Calculate the energy released from the seed by using this formula.



    4.2 is the value of the specific heat capacity of water, in joules per gram per degree Celsius – the number of joules taken to raise the temperature of water by 1 °C. 1 cm3 of water has a mass of 1 g

    3b) Test Tube A (Dry Cotton Wool)

    Factor: Water

    Will it Germinate: -

    Test Tube C (Boiling and Cool Water with oil suspension)

    Factor: Oxygen

    Will it Germinate: -

    Test Tube D (Put in Fridge)

    Factor: Temperature

    Will it Germinate: -

    3c) How would students know if seed is germinating

    Ans: Check for growth of radicle and plumule

    4) Sperm

    ai) Function of Head

    Contains genetic information to create baby (Has 23 chromosomes) And acrosome enzymes break down fluid surrounding egg

    aii) Mitochondria

    Produce ATP by aerobic respiration

    aiii) Tail

    Helps swim up through vagina to fertilise egg

    4b) Adaptation of Motor Neurone

    Ans:

    5ai) Stages 1 & 2 (I'm not sure it could be 5 and 2)

    5b) Reason for cooling milk to 45C

    Ans: At 80C Bacteria would denature at 45 optimum temp for activity

    5c) Why was stage 2 and 5 carried out

    Ans: Prevent growth of unwanted microorganisms...

    5d) I forgot question

    5e) What effects do adding fruits to yoghurt have on healthy skin

    Ans: Fruits contain many vitamins that help skin stay healthy

    6ai) Molecule made from Magnesium

    Ans: Chlorophyll

    Molecule made from Nitrate

    Ans: Proteins

    6aii) Ratio is 700 something is to one

    706:1 (Its not 706 but its 3 digits and starts with 7)

    6b) What happens when there is too much water in soil

    Ans: Less Actice Transport occurs and becomes water logged... (IDK answer)

    That's all I remember sorry if that didnmt really help but feel free to change and add stuff
