Q5.27. Snowshoe hares (pictured below) rely on camouflage to avoid predation. Their coats change color to match the environment. In Seeley Lake, Montana, climate change is producing shorter winters with decreased snow cover. As a result, many hares turn white in the fall before snow cover arrives (middle image below). Some ecologists suggest that the long-term persistence of this population would be more likely if the Seeley Lake population exchanged hares with other populations. What is the best explanation for how this could help the Seeley Lake population maintain its performance? O Exchanging individuals between populations could increase the rate at which the ranges of both O New arrivals could increase the phenotypic plasticity of the Seeley Lake population of hares O New arrivals could shorten the generation time of the existing Seeley Lake population, allowing populations shift to the North as temperatures rise. improving their ability to acclimate to climate change. evolution to occur more quickly New arrivals could increase the genetic variation of the Seeley Lake population, increasing the chances that its phenology could evolve.

Q 5.27- Option 2
which is that new arrivals could increase the phenotypical plasticity of the seeley lake population of hares, improving their ability to acclimate climate change. This mean enough number of genetic variaty of this population can evolve the timing of their molting making way for new growth by sheding old furs , that the population would keep up with the climate change.
Q 5.28 - Option 3
which is behavioural acclimation , this means behaviour or movement as behaviour in response to their predators
