Coach taylor is trying to explain the negative side effects smoking has to athletic performance. which of these options include both a scientific model and a connection to coach taylor’s topic of athletic performance? a. show pictures of the lungs of a smoker as compared to a non-smoker b. write the chemical formulas for carbon monoxide (found in tobacco smoke) and oxygen, comparing the two substances c. diagram the flow of oxygen-rich blood through the body of a non-smoker. then diagram the flow of blood with less oxygen (from airway resistance) through the body of a smoker d. list some diseases linked to smoking: cardiovascular disease, lung cancer, emphysema

the answer is B. I hope this helps :)

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.
