Why do Bees Die when they Sting us?

Honeybees are the only bees that die after stinging.

But if they die, why do they sting?

Bees only sting when they feel we are a threat to their queen or their hive. Now, the stinger of a honeybee is barbed. After stinging, it can easily come out, if the skin is thin. But since human skin is thick, the barbed stinger gets stuck. Hence, when the bee tries to pull herself, she ends up tearing the abdomen, leaving behind her venom sac, parts of the digestive tract, etc., and thus, killing herself. Now, although the bee is dead, we should make sure that we remove the sting. This is because in spite of being detached from the bee, the venom sac continues to pump venom, thus increasing the pain.

AMAZING FACTS ABOUT KANGAROOS

Kangaroos only sweat while they are hopping. When they stop exercising, they pant, just like dogs do. A kangaroo mother may have a newborn joey and a much older baby (called a yearling) nursing at the same time. Each one will get milk that is formulated to suit him best nutritionally. Strangely, kangaroos burn less energy the faster they hop… up to 20 miles per hour. A group of kangaroos is called a mob. A male kangaroo is called a buck, a boomer, or an old man. A female kangaroo is called a doe or a flyer. For a long time, people thought the word kangaroo meant "I don't know" in an aboriginal Australian language. Probably, the word comes from gangurru, a native name for one kind of kangaroo.

How ASPs works?

The Web and the Internet began to really heat up and receive significant media exposure starting around 1994. Initially, the Web started as a great way for academics and researchers to distribute information; but as millions of consumers flocked to the Internet, it began to spawn completely new business models. Three good examples of innovative models include: • Amazon - Amazon (which opened its doors in July, 1995) houses a database of millions of products that anyone can browse at any time. It would have been impossible to compile a list this large in any medium other than the Web. • Ebay - Online auctions make it easy and inexpensive for millions of people to buy and sell any imaginable item. It would be impossible to do this at a reasonable cost or in a timely manner with any medium other than the Web. • Epinions - Thousands of people contribute to a shared library of product reviews.
