Three-spined stickleback fish (Gasterosteus aculeatus) show substantial heritable variation in gill-raker length related to differences 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?Question 8Select one:a.directional selectionb.stabilising selectionc.disruptive selectiond.sexual selection

Which of the following situations will lead to natural selection?Question 2Select one:a.The seeds of two plants land near each other and one grows larger than the other.b.Two types of fish eat the same kind of food, and one is better able to gather food than the other.c.Male lions compete for the right to mate with females, with only one possible winner.d.all of the above

Paragraph 3: Creatures living in the upper part of the mesopelagic, where light intensities arehigher, are more likely to be transparent. Zooplariktor that penetrate the deeper levels of themesopelagic are commonly orange, red, or purple but in the blue-green background light areperceived as black or inconspicuous gray. Some mesopelagic fish have elongate (long and narrow)bodies, which may be a means of extending the length of the lateral lire—a vibration-detectingorgan—thereby raising sensitivity for detecting predators or prey.1. According to paragraph 3, which organisms are likely to be transparent?A: Those that are not good at detecting preyB: Those that live in places where the light is blue-greenC: Those with elongate bodiesD: Those that live in the brighter part of the mesopelagic zone
