Why don’t polar bears freeze in the icy Arctic waters?
In a polar bear’s Arctic home, winter temperatures can drop as low as –50 degrees Fahrenheit (–45 degrees Celsius). A polar bear spends the winter living on sea ice, but the bear is so well insulated that it doesn’t freeze in these extreme temperatures. A layer of fat more than four inches thick, a thick fur coat, and special white hairs that absorb the heat of the Sun keep the polar bear warm. During ice storms—when wind and blowing snow make travel and hunting too difficult—the polar bear curls up and lets the snow cover it completely. Although this stunt sounds chilling, it is warmer under the snow than aboveground, where the animal is exposed to the freezing air.

  • What to Eat in Bihar


    Among the Muslim Cape Malays of South Africa, pakoras are known as dhaltjies, and are usually eaten as an appetizer during iftar, or as appetizers for weddings, births, or similar occasions. In southern states of India, such preparations are known as bajji rather than pakora. Usually the name of the vegetable that is deep fried is suffixed with bajji. For instance, potato bajji is sliced potato wrapped in batter and deep fried. In such states, pakoda is taken to mean a mix of finely cut onions, green chillies and spices mixed in gram flour. This is rolled into small balls or sprinkled straight in hot oil and fried. These pakodas are very crisp on the outside and medium soft to crisp inside. There is also a variety that is softer overall, usually termed medhu pakoda in restaurants, that is made of any other ingredients, such as potatoes.Pakoras are popular across Pakistan, where they generally resemble those found in India. They are sometimes served in a yoghurt based curry (salan), as a main dish, pakora kari, rather than as separate snacks. In this case the pakoras are generally doughier and are made of chopped potato, onion and chili mixed into the batter, instead of individual fried vegetable slices.
