Tim and Stephanie are devastated when they find out their newborn son has hemophilia - an x- linked recessive disease. Tim is shocked because neither he nor his wife have hemophilia. He
figured if his son has the disease, he must have gotten it from him. Is Tim correct in his
thinking? Explain. Also explain what genotypes Tim and his wife must have for neither of them
to have the disease, but to have a son who has it.

First of all, hemophilia is an x-linked recessive and recessive disease. So it's a genetic disease.

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.
