13. In cats, there is a coat color gene located on the X chromosome. This gene is a different gene from the black/Siamese gene discussed in earlier problems. This gene has two alleles orange and black. A heterozygous cat has a tortoiseshell color (a splotchy mixture of orange and black) Predict the genotypic and phenotypic frequencies among the offspring of the following crosses Pay careful attention to the genders of the offspring Black female X Orange male Orange female X Black male Tortoiseshell female X Black male Tortoiseshell female X Orange male

uh two lol

bc blah

explanation:

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

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.
