Consider the heavily armored stickleback fish population thatcolonized the lake. If all the individuals in that population weregenetically identical, what do you predict would happen when theycolonized the freshwater lake?
| The population would increase, as it has increased foodresources. |
| The population would evolve through natural selection to bebetter adapted to its environment. |
| The population would decrease due to more juvenile fish beingeaten. |
| No answer text provided. |
Which of the following are adaptations?
| Thicker beaks on finches that allows them to eat large seeds,when large seeds are the most abundant. |
| Less armor on stickleback fish in freshwater that allows themto grow faster to avoid predation. |
| More armor on stickleback fish in the ocean that prevents themfrom being eaten by larger predators. |
| None of the above. |
| All of the above. |
