No, not truly... In true hibernation, an animal's temperature and metabolic rate lower much more than occurs in the bear. Further, the hibernating animal arises periodically to eat, urinate, and defecate before returning to its slumber. The bear does not awaken by itself (but can be awakened by noise or other disturbance).

Further, the female bear awakens during this time to give birth to cubs. However, as the bear utilizes this modified version of hibernation (for lack of a better term), it more easily returns to a normal state of activity upon completion of the cycle than an animal which utilizes a traditional hibernation cycle.

It depends on what you mean by hibernation. Bears do go into a deep sleep when their food becomes scarce. Some scientists do not consider this true hibernation because their body temperature does not drop like it does in other animals that hibernate (like snakes), and they can wake up and move around during their hibernation period sometimes.

This is currently being debated by scientists, but most agree that bears go into "torpor", which is like a semi-sleep, but the bear is still a little alert, but very groggy. I hope this helps.

Yes, bears hibernate They must to survive the winter months. Their metabolism slows say down while hibernating (in fact there is a study right now about animals hibernating relating to human transplants and extending the life of organs while out of the body). They accumlate extra fat before the winter season, their hearbeat drops from 50 beats to 10 beats per minute, their temp also drops about 10 degrees below nomral.

Bears can lose up to 40 percent of their weight while hibernating.

Yes Yes they do. They have all kinds of special body features that allow them to slow waaay down for a long winter's nap. See wikipedia..

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
