    You usually have to state implications from scientific report.
    Otherwise that is a valid implication.

    Hi. I was wondering which experiments we need to cover for the exam. I've studied totipotency and plant tissue cultures, strength of plant fibres and effect of garlic and mint on bacterial growth. Do we also need things like effect of temperature on membrane permeability, investigating factors affecting initial rate of reaction, effect of caffeine on Daphnia heart rate and effect of storage temperature on the vitamin C content of fruits? I thought they were part of Unit 1 and so haven't touched them. My exam's in 7 hours and I'm freaking out. Somebody please help.

    Use this formula (max mean-minimum mean÷original mean)×100 the ans you get will be the percentage but in this case you should need to know the original mean which will be given in the question

    How do we calculate the magnification? Also, how do we know whether the Bibliography is reliable or not?

    The independant variable is always in the x-axis and the dependant is always in the y axis. For eg in the vitamin C experiment the volume of juice needed to decolourise DCPIP depends on the temperature. therefore temperature becomes the independant variable and the volume of juice required to decolourise DCPIP becomes the dependant variable (as it is dependant on the temperature). hope this helps!
