Apopulation of rabbits has individuals with fur coloring that ranges from white to brown. the population lives in a temperate
deciduous forest where the summers are mild and average about 50°f. the winters are often below freezing.
if warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer, what do you expect to
happen to the population?

Adaptation is the process in which an organism adjusts itself to survive in its surrounding. Adaptation can be affected by climate, rainfall, predators, and temperature.

The population of rabbits will be:

Option B: The percentage population with white fur will decrease.

In the given case, the fur of rabbits ranges from brown to white. The changes in the fur colour are due to the adaptability of rabbits to the given environment.

In winters, white fur is by rabbits because it will help in camouflaging in a snowy environment, which will provide them high chances of survival and reproduction advantage.

Conversely, the brown fur will be better suited in the summer as they will be easily camouflaged in brown trees, soils, and plants.

The rise in temperature will cause a decrease in the rabbits with white fur. The brown fur rabbits will have more tendency to survive and reproduce in summers.

Thus, the population of brown fur will increase in high temperatures and rabbits with white fur will decrease.

Therefore, option B is correct.

Answer from: brook633

The correct answer is B. The percentage of the population with white fur will decrease

Explanation:

In the case presented, the fur of rabbits is related to an adaptation to survive during different seasons. In this way, the white fur is needed during winters as this helps rabbits to camouflage in an environment of snow providing them with a survival and reproduction advantage. On the other hand, the brown fur is better during summer as they need to camouflage between the brown trees, grass, and plants.

According to this, if temperature increases and therefore snow decreases the rabbits with brown fur will prevail as this will make them more likely to survive and reproduce, for example, a rabbit with white fur would be easily found by predators if there is no snow. Thus, in this case, "the percentage of the population with white fur will decrease".

Mantle convection is the slow creepingmotion of earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.[1][2] the earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. this hot added material cools down by conduction and convection of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction usually at an ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4] while in other regions, this material is impeded from sinking further, possibly due to a phase transition from spinel to silicate perovskiteand magnesiowustite, an endothermic reaction.[5]the subducted oceanic crust triggers volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6] and mantle plumes.[7]it is because the mantle can convect that the tectonic plates are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the hadean period, resulting in gravitational sorting of heavier molten iron, and nickel elements and sulphides in the core, and lighter silicate minerals in the mantle.
