The arctic fox has adapted to its environment in a number of ways. Its fur turns white in winter and it does not begin to shiver
until temperatures plunge below 10 degrees Fahrenheit. Global warming is likely to bring many changes, including an increase in mean air temperature. Over time, the arctic fox will have to adapt to this change. Which adaptation is MOST LIKELY to occur? A) Its paw pads may thicken.
B) Its fur may stay white longer.
C) Its tail may have thinner fur.
D) Its ears may be shorter and rounder.
I would say C. Why I say this is because fur is used to keep an animal warm. If the animal no longer needs to be kept warm, then it no longer needs the thick fur.
Arctic fox is well adapted to live in colder regions. It has got its body designed in that way only.
It has fur on body which provides thermal insulation from the colder environment. Due to rise in temperature, the arctic fox will have to adapted according to the changing conditions.
Its tail might have thinner fur, because thick fur is required to provide warmth which is no more required.
The Axon or nerve fibre is a long, thin projection of the neuron or nerve cells that sends signals in the form of electrical impulses from the cell body (soma) to the synaptic terminals. The axons are of two types: myelinated and unmyelinated. The unmyelinated axons lack myelin sheaths which make the transmission of electrical impulses slower while the myelinated axons transmit electrical impulses faster.
