Which of the following would NOT be true of cDNA produced using human brain tissue as the starting material? Which of the following would NOT be true of cDNA produced using human brain tissue as the starting material? It could be labeled and used as a probe to detect genes expressed in the brain. It lacks the introns of the pre-mRNA. It could be amplified by the polymerase chain reaction. It was produced from pre-mRNA using reverse transcriptase.

not only is it colder, it also becomes darker, less salty, and more dense.

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.
