    sorry didnt read the question properly :oops:! the genetic diagram will be same: Aa * Aa A---a__*__A---a AA---Aa---Aa---aa only aa shows recessive characteristic. genotype of those with recessive characteristics is only aa Therefore, the probability of the recessive being homozygous is 1/1 as...

    its metres per second not metres per hour easy: numerator--->km to m = multiply by thousand. denominator--->hours to second = multiply by 3600 overall = multiply by 1000/3600 denominator---> kg to g = multiply by 1000 overall ---> multiply by 1/1000

    actually they dont usually check for the calculator models and pupils have been known to take these calculators. The invigilators at most just erase your programming if it is a programmable calculator. After all, more than 50% of the pupils have the most recent calculator. They cant take away...

    actually, the volume of alkali needed to neutralise an acid is the point where an acid (H+ ion) is in excess to when an alkali (OH- ion) is in excess. It is actually very difficult to exactly pour out the same number of OH- ions as there are H+ ions, so the little excess of OH- ions results in...
