Answer:
if the lacI gene, in the genetically engineered fluorescent strain were non-mutant but the lacO sequence on the chromosome is mutated to lacOc then,
in the presence of the inducer, the cells fluorescence will show
yellow; red
in the absence of inducer, the cells fluorescence will show,
yellow; no fluorescence.
Explanation:
when lacO is mutated with lacOc then constitutive mutation happens which lets the system to be on.
Thank you for posting your question here at brainly. Below are the choices. The answer is 4.
1)Cell signaling is observed in single-celled organisms that reproduce asexually through binary fission.
<span>2)The mechanisms of cell signaling are similar in organisms whose last common ancestor lived a billion years ago. </span>
<span>3)The pathways in primitive organisms, such as bacteria, are shorter than in those in advanced organisms, such as humans. </span>
<span>4)Simple forms of life that have not evolved much since the origin of life, such as prokaryotes, use cell signaling.</span>
<span>Human influences in the Arctic are both seen and unseen. Human activity has seen a dramatic change in the arctic due to climate change. This is, by far the worse impact human activity has had on the globe, but in particular, the Arctic is fragile. Other human influences are the vast and untapped oil reserves in the Arctic have made it a target for oil companies. Oil and gas pipelines are a huge human influence in the Arctic. Garbage and other waste not to mention the impact of the oil and gas industry have left some parts of the Arctic polluted.</span>
Judging by the hair, you can find it's origin and as long as if you had a group of people to be looking at you can match the color and DNA of each person's hair to the hair you found when you were doing your forensics were at said crime scene. I don't necessarily know the processes that were taught but the <em>investigation</em> wouldn't be too difficult.
