the graph shows data from a decades-long study of cliff swallows, which nest along highway overpasses. the solid line represents the population of living cliff swallows; the dotted line represents that of cliff swallows found as roadkill.

which conclusion is best supported by the data shown?
a) differences in wing length are leading to speciation within the population.
b) individuals with longer wings are out-competing individuals with shorter wings.
c) alleles for shorter wings increase fitness, causing a change in the population’s gene pool.
d) deaths due to vehicular traffic are increasing, causing the cliff swallow population to decline.

C

Explanation: C, because the graph shows that, beginning in the 1980s, the wingspans of living cliff swallows has decreased. Over the same period, the wingspans of cliff swallows found as roadkill has increased. This indicates that natural selection is acting against the phenotype of longer wingspans, resulting in a population with shorter average wingspan. In other words, alleles for shorter wings increase fitness, causing a change in the population’s gene pool.

the correct answer is blue and green.

a visible spectrum is electromagnetic spectrum color that can be seen by a normal human being by a single wavelength of light. the visible light spectrum is the range of wavelengths that make up visible light. the visible light spectrum passes through a prism enabling the rainbow reveals all the colors in the spectrum. these range from red, orange, yellow, green, blue and violet.

i do believe that its called,(the segovia highlands); plz check first good luck;
