let's take a look at the definitions and see wich best maches with what she is looking for.
geology: the science that deals with the earth's physical structure and substance, its history, and the processes that act on it.
zoology: the scientific study of the behavior, structure, physiology, classification, and distribution of animals.
botany: the scientific study of plants, including their physiology, structure, genetics, ecology, distribution, classification, and economic importance.
meteorology: the branch of science concerned with the processes and phenomena of the atmosphere, especially as a means of forecasting the weather.
*the climate and weather of a region.
hopes this leeds you in the correct direction.
Natural Selection proposes that organisms that are better adapted to their environment are able to survive and reproduce.
Even though these frogs are the same species, their shades of green is what helps them to survive in their habitat. In this case, frogs with a lighter shade of green are able to be seen by predators easier, whereas frogs with darker shades are able to blend in (camouflage) more with their surroundings. After a period of time, due to them being easily seen, lighter-shaded green frogs will die off.
To anseer your question, natural selection would have a gradual affect on the frequency of the alleles. Lighter-green allele frequencies would eventually cut off, and darker-green allele frequencies will increase.
Hopefully the following image will help:
As seen in the image, (please forgive the quality, as I had drawn this on some random kids drawing site on the internet...) you can see the affects of natural selection on the allele frequencies. The brighter-green shades gradually decrease over time, as the darker shades increase.
Hope you find this helpful.

Answer:
Microtubules
Explanation:
These filament-like structures are a major component of the cytoskeleton of the cell and help is maintain asymmetrical cell shape. They are composed of tubulin molecules arranged to form a 'hollow straw' attached to the cell membrane end to end . The contraction and lengthening of these microtubules are controlled by the addition of removal these of tubulin molecules to vary its length.
