Three-spined stickleback fish (Gasterosteus aculeatus) show substantial heritable variation in gill-raker length related to diff
erences in their diets. Longer gill rakers appear to function better for capturing open-water prey, while shorter gill rakers function better for capturing shallow-water prey. Which of the following types of selection is most likely to be found in a large lake (open water in the middle and shallow water around the sides) with a high density of these fish? A) directional selection
B) stabilizing selection
C) disruptive selection
D) sexual selection
It is also known as the diversifying selection , it enables to describe the changes in the genetics of the population , in which the trait that is favored is the extreme over the intermediate values .
In case of disruptive selection , the trait variance increases and the population is distributed into two groups .
And , in this case the more individual acquire the peripheral character value in the both ends of distribution curve .
Hence , from the information of the question , the correct answer is disruptive selection .
While the sun does emit ultraviolet radiation, the majority of solar energy comes in the form of "light" and "heat," in the visible and infrared regions of the electromagnetic spectrum.
Answer: I think it's the third one: Letter Q points to the guard cell. Letter T points to the stomata and the response is most likely due to the humid tropical nature of the enviorment.
