From a hospital patient afflicted with a mysterious illness, you isolate and culture andthen purify DNA from the culture. You find that the DNA sample obtained from theculture contains two different kinds of DNA; one was labeled as double-stranded humanDNA and the other was labeled as single stranded viral DNA. However, a mix-upoccurred and the labels were accidentally removed from the test tubes. How can youfigure out which test tube contains which DNA?

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

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.
