Mr. James, the owner of Squeaky Clean Floor Company, invented a solution that he claims is better than the other top three selling floor cleaners. To prove his claim, Mr. James performed several experiments. His results appear below. Brand of Floor Cleaner Type of Floor Type of Debris Spread on Floor # of Trials Cleaned Floor? Squeaky Clean Brand Vinyl Dust 5 yes Leading Brand 1 Vinyl Grease 5 no Leading Brand 2 Vinyl Paint 5 no Leading Brand 3 Vinyl Mud 5 no Which of the following is true of Mr. James' experimental procedures and results? A. Mr. James' results are reliable because he performed the same number of trials for each brand of floor cleaner. B. Mr. James' results are biased. Since he is the owner of the floor company, it is impossible for his experimental set-up to be fair and reliable. C. Mr. James' results are biased. He selected different types of debris to make it easier for his floor cleaner to be effective.

B. Mr. James' results are biased. Since he is the owner of the floor company, it is impossible for his experimental set-up to be fair and reliable.

Explanation:

Under experimental bias, the participant is more inclined to try to influence or generate findings that indicate a favorable outcome of their experiments. In this situation, the organization plans to carry out work on the product that goes against its rivals.

This bias is always implicit and may be implemented at any point of the experiment; it is likely to influence the experimental design, data processing and evaluation of the findings obtained. The experimenter is likely to select evidence that better reflects their arguments while at the same time distorting the value of their rivals ' goods.

Double blind experiments are usually performed to minimize this potential bias.

answer: c.

explanation:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
