Some arctic species like the arctic fox (pictured above) grow white fur only in winter. In summer, it is a brown color. What exp
lanation best describes why animals like the arctic fox have this seasonal response in order to survive? A) the white fur keeps them warm B) the white fur helps them attract a mate C) the white fur helps them conserve energy D) the white fur helps them camouflage against predators
D) the white fur helps them camouflage against predators
Explanation:
Camouflage is a defense strategy in which living beings resemble the environment in which they live. In this case, individuals of a species may have a color, shape or texture similar to that of the environment and thus go unnoticed by their predator. However, the same mechanism can also be used by some predators to surprise their prey.
Camouflage is a result of natural selection and represents an adaptation that guarantees the survival of species in the environment.
An example of camouflage can be seen in changing the coat color of arctic foxes. In winter, the environment takes on a white color due to the snow. In order to hide from predators, the arctic foxes take on a white coat in order to be camouflaged with the landscape.
Polygenic inheritance is the pattern of inheritance where a wide range of phenotypes that result from many gene pairs in an individual organisms controlling a single trait.
Examples would include = skin colour and or measurement of height.
