Do all wild rabbits turn white in winter?

no. jackrbbits and cottontails don't.there may be others.

It depends.. iF htey live there all year round they have layers fo fat called blubber\nthey also have fur... polar bears have clear fur to collect heat and light and warm the bears. \n\nif they are travelling inbetween cold and warm( like humans d0)\nthey do things like shiverring and teeth chattering, also the blood rusehs to the skin to warm and away from the ears adn the feet to keep the inner organs warm

Actually the scientific community hasnt definitively decided yet what should or should not be classified as "true" hibernation. Compared to ground squirrels a bear seems to be only in a light sleep, but both animals go through similar process to get ready for winter etc... \n\nExcerpt from Wikipedia...\nOne animal that some consider to be a hibernator is the bear. However, the degree of metabolic depression is much less than what is observed in smaller mammals and many prefer to use the term denning. The bear's body temperature remains relatively stable (depressed from 37° C to approximately 31° C) and it can be easily aroused. In contrast, hibernating ground squirrels may have core body temperatures as low as -2° C.

Not quite but close. A Polar Bear's Skin is actually black and the individual strands of fur are pretty much transparent. The fur however is very good at trapping air and air is one of the best heat insulaters in nature. The helps the polar bear stay warm. A side effect of all that trapped air is that the Polar Bear will appear to be white.

In the spring and summer time, you'll hear them making a lot of noise.  two or three tones like Bob Bob White.  And in the winter, they are pretty quiet.  You may hear them just say Bob once in a while.

some of them might hibernate. hibernation allows some small mammals to reduce their metabolism during times of scarce resources, such as winter. they accumulate body fat for a while, then it's like their system «shuts down»: their body temperature decreases, their pulse too, and they might breathe as few as 1 to 10 times a minute!\nhibernation is a real advantage because, when it's cold, it would take a lot more energy to keep normal body heat, consuming more nutrients, when, in fact, it's the time of year when it's more difficult to feed!

well here in NH USA our black bears do hibernate.. they start to wake up in the late spring ... but the warm weather here has brought a few out \n\nthe old timers have heard them  so i would say yes for here any how

The wool is brushed from the rabbit.  They are not harmed, at least in most instances.  The rabbit hair is then washed and weaved into wool.

Many bears of northern regions are assumed to hibernate in the winter. In fact, they don't hibernate. Their body temperature sinks a moderate amount and they can be easily awakened.

No, animals grow hair in response to temperature and daylength. They don't watch the calendar and decide that it;s time to grow a winter coat. Day length shortens and temperatures fall in Autumn in the southern hemisphere just as it does in the North. The names humans give to the months dont; alter those things.\n\n>>>>In the southern hemisphere Jan.-March are summer and\n>>>> July-Sept. are winter.\n\nMore commonly Dec-Feb are summer and Jun-Aug are winter.\n\n\n>>>>It can't be the temperature if he's an indoor cat and it's 70 degrees year round. \n\nIt can be if the temperature fluctuates at all between seasons. Animals usually respond to temperature changes, not to specific temperatures. Unless your house is heated to a constant 70 all winter and cooled to a constant 70 all summer, 24 hours a day, the cat could easily detect the differences.

Its rare, but it can lightening when it snows

The white is the color that is reflected to our eyes when it reflects off a pack of snow.  As snow accumulates there are millions of surfaces that this light can reflect from.  You can not see through the snow even though it is frozen water because of this.  \n\nIf you look through a microscope at one snow flake it is pretty transparent but not completely.  That is because the amount of reflective surfaces are only a few and going in only a few directions.

Good question.  Maybe they never get cold, but then again, they are always that pasty gray color so who knows.  Now you have me curious.  I'll ask the next one I see.

during winter season,the plant does not prepare its food.that means it doesn't require chlorophyll which is used in photosynthesis.the color of the leaves of the plants is due to chlorophyll but otherwise the leaves are actually yellow or orange etc in color so in winters when chlorophyll pigment disappears,the leaves shows its true color.the leaves dry because of lack of food and water which is not necessarily during winters only,it can be due to injury or disease etc also.

It is the very complicated surface of the snowflakes.  Ice and water may be clear, but some light is reflected, and some gets transmitted.  In the case of snow flakes, which are ice cristals, there is so much surface to reflect off, and light transmitted leaving off the back will strike the next snowflake behind (or the next bit of the same snowflake, deeper in) and eventually reflect back.  Since the shape is so weird, no coherent reflection can be seen, hence no good mirrored surface.  But the light will come back looking the same color as going in, hence white.

Actually deer do migrate\n\nWhite tailed deer\n""Seasonal migration is common of white-tailed deer (Odocoileus virginianus) in the northern portion of their range. Severe winter weather coupled with changes in food supplies influence deer movement patterns. Little information related to white-tailed deer movements exists for farmland deer populations""\n\nMule Deer\n""DeerVehicleCrashes with mule deer are most frequent during the spring and fall migrations.""\nMigration Routes->http://www.nww.usace.army.mil/bpca/pdf_files/Migration-Routes.pdf\n\nRed Deer\n""...in Central Yakutia, where the red deer migrates,...""\n\nIf you would like to know more just do a search with google for deer migration, I came up with 1.620,000 pages
