If the lacI gene in the genetically engineered fluorescent strain were nonmutant but the lacO sequence on the chromosome mutated to lacOc, how would the cells fluoresce in the presence of inducer? In the absence of inducer?

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.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
