the noniflower is a plant that grows in soil with a ph of 7.4 to 8. a variation of this species, called the
mariflower, can grow at a more acidic ph. researchers observed an area where noniflowers typically
grow over a period of 50 years. their data showed that the number of mariflowers slowly increased and
the number of noniflowers slowly decreased. the impact of environmental factors on this trait shift was
also documented.
explain why an increase in precipitation and in the number of nearby factories has a greater impact
on the occurrence of the mariflowers than changes in temperature, length of day, and invasive
species.

Data showed that the number of mariflowers slowly increased and  the number of noniflowers slowly decreased. The only difference mentioned between the two species is the  mariflower, can grow at a more acidic pH.

So environmental factors that have larger effect on pH will have higher impact on the two species. Increase in number of factories nearby will increase CO2, SO2 and other air pollutants. Increase in precipitation which means more rain will dissolve the pollutants in air and bring them to the soil; thereby changing the soil pH and the species' growth rate.

The other factors such as temperature, daylight and invasive species have less impact.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
