A metal cube has a volume of 1000cm3 at 0∘C. What will be its volume at 100∘C if the coefficient of volume expansion is

Given: V0 = 1000cm3, ΔT = 100∘C, αv = 5.4×10−5K−1. ΔV = V0αvΔT = 1000×5.4×10−5×100 = 5.4cm3. New volume: V = V0+ΔV = 1000+5.4 = 1005.4cm3. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 1005.4 cm³. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.

Coefficient of coincidence is defined as

Coefficient coincidence measures strength crossover interference experimentally during meiosis by comparing observed versus expected double crossovers. Expected double crossover frequency calculated assuming independence as product of observed recombination fractions for adjacent intervals, based on basic probability theory assuming no chromatid interference. Observed DCO frequency obtained by directly counting double recombinant phenotypes in large progeny sample. Ratio observed divided by expected defines C. If C =1 crossovers independent, no interference operating. If C
