polar bears fur is white
The fur, which appears to be white, is actually made up of almostcolorless, almost transparent hairs. However, the hairs are notfully transparent. They contain keratin. Kerati…n is almost clear but is off-white, the same as your fingernails, which arealso composed of keratin. Viewed side-on, the hairs appearcolorless; viewed lengthwise (as if one were looking down atelescope) the hairs no longer appear transparent. Reflection of the sunlight from the densely packed, almostcolorless hairs makes polar bears appear to be white in a sort ofoptical illusion. The long, coarse guard hairs are hollow, letting the warming raysof the sun reach to the dark skin that acts as a solar heatcollector. The air-filled guard hairs also help insulate the bearsfrom the cold temperatures. The hairs of the thick undercoat arealso nearly colorless, but are not hollow. For many years, scientists operated under the theory that theindividual hair might act as fiber optics taking sunlight directlyto the skin. This has recently been proven to be incorrect. Surprisingly, the polar bears' skin color is black. The bears'black skin absorbs heat from the sun. Under the skin is a thicklayer of fat in healthy individuals. Even in the coldest Arcticweather, the polar bear is very comfortable. The Polar bear canswim in ice laden sea water quite comfortably. It is more in dangerof hyperthermia (over-heating) than hypothermia (freezing). A polor bear has no color to its fur. Their fur is clear hollow tubes and almost not fur at all. It only looks white to the human eye because the sun reflects from it almost the same way water in a pond looks blue because of the sun. This 100percent true and based upon scientific sources. The outer fur of most polar bears is white. However, the skin underneath its fur is totally black. Polar bears fur is clear and is reflected bythe light with the snow and ice. Polar bears have black skin. Clear (I answered in this way and I could go on in the Inpossibly hard puzzle 3 game!)
The color of a polar bear's fur can vary. Colors vary from pure white, to a yellow-like hue. The outer hair is clear. (their skin is black)
the black skin helps them survive in hot weather. they eat fish...they hunt too
The polar bears fur is transparent.
Because thats the way God created them.
there is the Black and the Brown bear
Red!! what do u think its a BLACK BEAR
Black bears are born with fine, gray, downlike hair,
yes it along with their transleucent fur keeps heat in
because of the hotness of were it lives
