Consider an experiment in which nuclei were isolated from brain, liver, and muscle tissues. the nuclei were incubated with α - [ 32 p ] utp under conditions that allow rna synthesis, except that an inhibitor of rna initiation was present. the radioactive rna was isolated and annealed to various dna sequences that had been attached to a gene chip. in the diagrams of the gene chips, the shading intensity represents the amount of mrna attached, or hybridized, to each dna sequence.

"a scientist studying a whale and its surroundings would need to understand the structure of atoms in case something was negatively affecting the whale or its surroundings."

explanation:

this was from the link provided:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
