During the mining process, chemicals, which are toxic to living organisms, from the minerals gets washed into the areas surrounding the mining site. Thereby, causing serious harm to the wildlife living in those areas.
Answer:
elongation rate of strain of S.cerevisiae during transcription.
wild-type and experimental strain not treated with soultion of amanitin will be the control group. The elongation rate of mRNA of this group must be observed.
Explanation:
Dependent variable is one whose value depends on another value. Here effect of presence of mRNA polymerase enzyme and inhibtor on elnogatino rate of mRNA is being observed. So elongation rate is the dependent variable
Control group is one where independent variable whose effect is being observed can't influence the results. In experiment 2, the effect of inhibitor is being observed. So the control group must not have that inhibitor. Other conditions must remain same for experimentan and control group.
Answer: You Palpatine, I'd still have you.
