7) The allele N codes for a normal nose and the allele n codes for a green nose. If two individuals who are both heterozygous at this gene location mate with each other, what combinations of alleles will their
offspring have (genotypic ratio)? What will their noses look like (phenotypic ratio)?

the answer is b: 1.4 km/hr

which

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
