    How would you work this out?

    Two drivers take part in a race. The faster driver’s average lap time is 1 minute 6 seconds,
    and the slower driver’s 1 minute 10 seconds.
    Assuming they drive at a constant speed and started together, how long would it take for
    the faster to lap the slower driver?
    A 18 minutes 9 seconds
    B 19 minutes 15 seconds
    C 20 minutes 25 seconds
    D 38 minutes 30 seconds
    E 40 minutes 50 seconds

    OK, to the faster driver is 4 seconds faster than the slower one. So every lap, he gains 4 more seconds over the slower one

    So 1 minute 10 = 70 Seconds.
    70 / 4 = 17.5

    therefore it takes 17.5 Laps to overlap him.

    Eash lap is 1m 6 seconds, ie 66 Seconds

    so 66 x 17.5 = 1155 Seconds

    Converted into Minutes (divide by 60) = 19.25

    Which is very close to option B which is the correct answer

    Im not sure why I didnt get exactly the right answer, and I cant seem to find any flaws in what i done, but I got it right , so woop woop

    Hi Crazy lemon, i read your essays.

    I'm not very good on this constructive criticism thing, purely because i don't think im the most experienced at writing these essays! However in regards to your first one, it is a good essay however when i read the questions i interpreted it slightly different

    What i got from the quote was, in accordance to your essay also, that even though the body is essentially one largely complex machine with various different mechanisms all functioning in unison, and despite an encyclopedia of scientific knowledge there is still so much we don't know about the body therefore we cannot treat it as a " predictable" mechanism as such". For it might be appropriate to treat the body as a mechanism in the given example of renal function, it is known that a will lead to b which will result in c however taking the brain for example, it is an organ very much foreign to scientists. Therefore we cannot treat it as a mechanism becasue we don't know much about its function, or more HOW to treat it.

    From another perspective, i also found that the quote appealed to our mental state ,whereby our physiological being represents that of a complex machine at the end of the day we experience emotions and have feelings.

    I don't know if this helps at all! i am very new to this!

    Please check my essay too its on the previous page! x x x

    First I worked out how much protein it would require using the protein requirement table and that came out as 6.37 (tell me if you can't work it out and I'll show you my individual steps). Then I did 91 (the energy requirement) x 0.06 (the protein that CCFR gives you) which = 5.46. And the difference between 6.37 and 5.46 (0.9) is the answer.
    thanks:o:

    19.25 is the same as 19mins15secs

    I actually did it blip's way and got the same answer (multipying 16.5 and 70) so I'm guessing you can do it either way?

    Yeah I got 19mins 15 seconds. When I did 1155/60 I got 15 as the remainder but cos it was over 60 it meant 15seconds and not .15... That might be where you got muddled up?

    I have had a look at you essay and did find it good however a few things

    Im not sure that stem cell research has cause the developement of artificial insulin - I though it was by the GM of bacteria. However maybe I have missed some research or something not certain.
    I liked the example of how we certiainly havent stoped other organisms from evolving.
    One thing I might have added myself was that possibly the criteria for natural selection have changed for humans; some characteristics may cause you to still have more children than others and so natural selction still aplies to us; not every human has the same number of children.

    Depends on the question I'm normally trying to work out how to do it nad finding a solution as I read the question (the only thing mechanics has ever help me with)

    Could someone please look at my essays its the bit im least sure of
    (In spoilers)

    It Is ridiculous to treat the living body as a mechanism

    What doe the above statment imply?
    Give examples that illustrate why it might sometimes be sensible to treat the body as a mechanism and others that illustrate the opposite.
    How might you resolve this contradiction?

    Spoiler:
    Show

    The above staement implies that the body is not a mechanism; its behaviour is too chaotic for it to be described in a mechnistic manner.
    An example whe it is sensible to treat the body as a mechanism would be hormone production, for example, ADH levels. When the water level in the blood drops this is detected stimulating the production of ADH which then causes the kidney to reabsorb water. So in this situation the body can be treated as a simple mechanism with cause and effect; A follows B which follows C.
    An example of a situation where the body may not be treated as mechanistic would be cognitive function and emotions. The reaction to a given stimulus varies greatly from individual to individual and a simple mechanism cannot explain this.
    A possible solution to this apparant contradiction is that the body is too complex a mechanism for us to understand currently. This could be due to chaos theory; small changes in a situation may greatly affect the total outcome. In this sense the body could be likend to the weather, somthings are easy to predict such as, 'will it snow tomorrow' whereas long term prediction is not currently possible.
    In conclusion currently the body may not be treated soley as a mechanism as we don't know how all varibles that may affect it and how they do so. But some aspects of the body when veiwed in isolation may be treated as mechanistic.


    Our unprecedented survival has produced a revolution in longevity which is shaking the foundation os societies around the world and profoundly altering are attitudes to life and death

    This is a statement concerning ageing and longevity; explain what you think it means. advance an argument against this statement ie in favour of the proposition that 'a revolution is not shaking the foundations of societies around the world'.

    Spoiler:
    Show


    I think that the statement means that as life expectancy has increased it has caused the demographic of countries to change resulting in a greater strain on services and an increased ratio of dependant elderly on the rest of society.
    This premise of increased longevity was then taken to the extreme by John Wyndham in his book 'Touble with Lichen' where a compound was developed that would increase life expectancy by a factor of up to 10. He envisaged that this would cause: generations of unemployed, people waiting years for promotion and a population explosion straining natural resources.
    An argument that out increase longevity is not shaking the foundations of societies is to use the example of Japan. Japan has a high life expectancy and a large number of elderly. It has solved these problems through increase automation which has rendered large numbers of physical jobs unecsary; one person can do then with a machine, eg digging. This has meant that fewer actively working people are needed to support the increasing number of elderly; Japan as one of the wealthiest and most succesful countries on the plannet.
    The problem of over population due to increased life expectancy may also be averted naturally; birth rates are decreasing. This may be due to the fact children are less likely to die in childhood so a large number of children is not necessary.
    However, there may be some changes of significance. for example as there is an increased number of old individuals euthanasia may become more significant as there are more people in extreme pain unable to end their own lives and who need assistance to do so. This may get to the point where legislation may need to be changed.
    In conclusion while it is unlikely our longevity will grealty alter society attitude to certain topic may alter.
    question.... where do you find these titles????

    This may seem weird, but when you actually do these BMAT questions, most of the time the answer is starring you in the face. Which is probs one of the better things about BMAT, Ive noticed that when i go through some of these problems, the answer seems to star me in the face, even when i think, i havent done it.

    OK.

    If we have 1000 Men.

    Stage 1

    10% will have an abnormal PSA Level, leaving 100 Men
    Of these, 74% will be false poitive, leaving 74 Men


    Stage 2

    It says 85 men in 1000 will have a false positive, so thats 8.5%
    So 8.5 % of 74 with out calculator :

    10% = 7.4
    5% = 3.7

    You dont need to work it out, you looking for a value bigger than 3.7 and smaller than 7.4, so the answer is B (6)

    Vitamic C --> Glucose, you're taking away 4 hydrogens. Which is oxidation I'm guessing?
