in the food to grow, and drying effectively prevents them from surviving in food (Desiccation,

What happened to the bears when placed in salt water? - When placed into salt water both of the bears shrunk in size. The Distilled bear reduced to about -44% , while the Tap bear decreased by -17%. This happened because the concentration areas were to high in the gummy bears and the molecules transported into the salt water where there was a lower concentration

The white phased black bear was said to have traversed barriers of the sea during the last ice age when glaciers covered most of northwest British Columbia. When temperatures started to rise, and glaciers started to retreat it is believed that the white bear was then isolated on the islands off the coast of BC. The white coats would suggest an adaptation to the white snow for hunting, however if that was the case, the evolutionary trail should have left the recessive gene behind when it was no longer useful to them in the temperate forests. Most research that is done on the Spirit bear is to try and understand the polymorphism of this species and how it has come to last among a low frequency in a minute area. Evidence now suggest that the reason for the white fur is actually a very important adaptation for the bear and is still very useful even in the array of

The Polar Bear (Ursus maritimus) is a bear native largely within the Arctic Circle encircling the Arctic Ocean, its surrounding seas and land masses. Although it is closely related to the Brown Bear, it has evolved to occupy a narrower ecological forte, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Though there are many theories surrounding evolution, the two stand outstanding hypotheses applying to the modification from Brown Bear to Polar Bear are Lamarck’s theory of Use and Disuse, and Darwin’s theory of Natural Selection. The intention of this paper is to compare these thesis and determine the most appropriate in

Nearly 100 black, white bears exist on this big and beautiful world. This type of bears are nearly extinct, Because people try to hunt the extinct animals. Black white bears have a rare double recessive gene in it’s body. This is how people have the white and black fur. When 2 parents have the same recessive gene the result is white fur for their young. A lot people think that these bears are Polar Bears or even Albino’s, but they are just Kermode Bears.

American black bears play a key role in hunting for preys such as deer, beavers, and small woodland mammals. When hunting, these bears tear apart logs and any obstacles they might encounter. Bacteria, fungi, and worms benefit from this action as they are able to gain their nutrients by aiding in the decomposition in forested environments. American black bears are omnivores, meaning they get both meat and plants. Most of their diet are plant based such as berries, seeds, grass, and honey. Their consumption of berries and other fruits, help with the distribution the seeds of various fruits. Small species such as squirrels and birds benefit from this as they are able to obtain their food.

The grizzly bear was first found in Big Madly Creek on April 29, 1805. The grizzly bear is found in Southern and Northwestern states. You could also find them in Idaho, Montana and Wyoming. Sometime they wander into Washington and, Colorado. The grizzly bears usually can be found in the mountains and open areas near rivers and streams. The grizzly bears fur is brown and tan. The ends of the hair had white tips. The grizzly bear had claws and walks on all fours.

In the article “How a Water Bear survives, Even When It’s Dry” illustrated a way genes with the ability to help living organism adopt and survive harsh environment. Tardigrades a microorganism that able survive in the cold and warmest environment for decent through the process of anhydrobiosis. When this organism approach the frozen or dry state, itself form a ball shape structure. The unique genes of tardigrade allow them to create proteins that known as tardigrade-specific intrinsically disordered proteins which can protect and hold the water bear’s cells intact to prevent any damage from happening during the state of desiccation, until it rehydrate itself it will remain this this

It uses the algae on it for camouflage to hide from predators and they don’t use adaptations for hunting.

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

Now Ben was sitting on his throne, watching over the bears as they hunted their beluga whales and the seals. The bears loved seal fat, and it was as valuable to them as gold. Bears had a tax and agreed to give Ben 10% of their seal fat. With this, ben gave about 5% to the poor or old bear to live, and he ate the other 5%. In addition to the whales or seals, the polar bears occasionally ate berries or vegetation, but this was usually when times were rough. Winter was coming to an end, and mating season would start. Since it was already March, Ben decided to take a look at the large freezer the bears had. “Somebody please escort me to the giant freezer,

However, Liu, S et al. (8 May 2014) pointed that, the most interesting part is that besides helping the bears to keep warm, the fat layer has another significant function----it is the water supply of a polar bear. Living in the polar area where fresh water is hardly found, the decomposition of fat can produce much metabolic water and make up for the lack of fresh water so that polar bears can survive. These inspiring features of polar bears can be applied into our scientific researches.

3. Some polar bears are drowning because they have to swim longer distances to reach ice floes.

Water bears, scientifically known as tardigrades, are puffy, microscopic creatures. The name “water bear” comes from zoologist J.A.E. Goeze in 1773 because of its strange similarity to bears (Bordenstein 2017). All tardigrades are noted as aquatic because they require a film of water to exchange gas (Lindahl and Balser 1999). Tardigrades have been found everywhere, therefore, they need to adapt to every kind of environment. Tardigrades can survive below freezing temperatures as well as above boiling temperatures.

Water is essential to the lives of millions of organisms, whether it be involved in processes such as photosynthesis or respiration, this simple molecule is heavily relied upon by individuals from each domain. Many of these beings, however, are often situated in areas that have little to no water available, and so have to exploit a variety of different strategies to stay alive. Anhydrobiosis, for example, is a reversible process which allows certain organisms to survive in these extreme conditions, and it essentially causes their metabolic processes slow to almost a complete stop. The process of anhydrobiosis is triggered due to a lack of moisture in an organism surroundings, resulting in the individual(s) entering a state of desiccation;
