    Biology MCQ thread..!!

    Yes it is BUT that is not the reason. Babies require a gradual release of energy because their body's circulation system can not cope with large amounts of energy at the same time.

    Physics Paper 1 2011 Discussion Thread

    Thanks. The answer should be B because the formula for calculating density is Mass per unit volume. Therefore, the mass of the liquid should be (mass of beaker+liquid) - (mass of beaker alone) that should work out to be (70-20)=50g. No matter if you're subtracting any two physical quantities...

    2 and 3 are correct (therefore, C). Two Cl atoms can not be added because Bromine is more polarisable while NaCl requires large amount of energy to be dissociated. Also, elements below in the electrochemical series get discharged preferrably.

    BIology Paper 34 Tip Off's (100% True)

    ALWAYS test for reducing sugar first. If results come out negative, carry out the test for non reducing sugar. Even then if the results are negative, means no sugar was present (: For fats test, you add an equal volume of NaOH followed by equal volume of cold water. This will form white...

    Biology P22 Was Quiet Easy !!!!

    Hey I want to know how does this percentile system work. If you score, say around 50 in any paper 2, a good 35 above in MCQ paper and a decent score on the practical, how do they calculate your grade? Do they calculate like 50+35+37/140 and then multiply by 100 and see what percentage the...

    Urgent Help In Biology!!!!

    Just make it a point whenever you answer a Biology Theory question, look at the demand of the question, the amount of marks associated with that question and try to figure out what the examiner really wants you to stuff into your answer sheet. Jot down those points with a pencil on the side of...

    GT For Chem 22

    Kc was 2.25 and not 0.44 and had no units. Empirical formula was BaO2 (Barium per oxide) and it reacts with dilute H2SO4 to give BaSO4 and hydrogen per oxide (H2O2)
