If participants who receive the thc (marijuana) pill are frequent marijuana users and participants who receive the placebo pill are first-time marijuana users, this is an example of a(n)

The correct answer is "confound".

Explanation:

In clinical trials, confounding is defined as a situation at which a known prognostic factor is unevenly distributed among the different groups of study. In this case, the prognostic factor of "frequency of marijuana use" is unevenly distributed between the group of participants receiving the treatment and the group of participants who receive the placebo pill. This is an example of confound, a situation that must be corrected in order to have valid results among the different groups of study.

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i

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.
