  • When a bee/wasp stings you, is it trying to kill you?

    Best answer: No. It stings in self defence. Or as a consequence of suffering Disorientation. Shooing them away, is seen as an hostile act, feeling under threat they send out an S.O.S distress signal, which brings in reinforcements. Ouch.

    Best answer: No.
    It stings in self defence.
    Or as a consequence of suffering Disorientation.
    Shooing them away, is seen as an hostile act, feeling under threat they send out an S.O.S distress signal, which brings in reinforcements. Ouch.
    Some types of bees DIE as a result of stinging, as releasing their stinger tears their body apart, but it ensures their colony survives.

    The PRIMARY purpose of the female wasps, and bees using a modified egg-laying apparatus, a ovipositor i.e. a stinger, is to subdue prey and to defend their nests. They sting rather than bite. To inflict injury they may also use their mandibles to bite in order to anchor themselves before delivering the sting.

    http://www.dailymail.co.uk/sciencetech/article-3529726/When-wasps-ATTACK-Experts-reveal-evil-insects-target-avoid-stung-killing-one-cause-army-swarm.html "ever been stung by a bee or wasp, you might think the attack came out of nowhere, but bees and wasps will only sting when they feel threatened.
    They are social animals and often their attacks are as a response to a particular chemical given off by other members of their hive.

    Now the science behind these attacks have been explained in a video by The American Chemical Society.

    Most of the 20,000 species of wasps are solitary, but because solitary wasps do not sting, most humans are more familiar with social wasps, who live in complex communities.
    Only female bees and wasps can sting. Males do not have the egg-laying organ that is modified into a stinger on female insects.

    Unlike bees, female wasps have the ability to sting a target multiple times because their stinger does not fall off after use.
    Social wasps and honeybees both use pheromones, secreted or excreted chemicals that trigger a social response in members of the same species.

    Wasps and bees will not sting someone at rest if they have not been disturbed by some agitation of their nest or threatened by swatting or quick movement of arms or legs.
    They may land on someone's skin to inspect a smell or get water, but they will leave if the person stays calm and does not move quickly.

    Both social wasps and honeybees use alarm pheromones to warn their buddies about nearby dangers,' says Ms Cai.
    These chemicals are secreted by some of the group when they think they are in danger, like if the nest is disturbed or one of them is killed.
    'If a hive or nest is disturbed, guard wasps will send out these guard molecules to rally the troops,' she says.
    The rest of the wasps react to the pheromones by swarming out of the nest and attacking the intruder."

    How dangerous are wasp and bee stings? Anaphylaxis occurs quickly following a sting, even in individuals who have experienced no previous reaction. Symptoms of anaphylaxis?

    Social wasps = paper wasps, mud daubers, yellow jackets, hornets, and umbrella wasps.

    Are we capable of creating a weapon even more powerful than the asteroid the killed the dinosaurs? For those who know. The asteroid's estimated energy is about 10 billion Hiroshima A-bombs about 100,000 EJ. Compared By contrast, the most powerful man-made explosive device ever detonated, the Tsar Bomba, had an energy of only 210 petajoules. But are we able to make a bomb that puts out more power than the asteroid that killed the dinosaurs. It doesn't matter how much money it costs, how long it takes to make it. As long as it's more powerful (no matter now much (slightly or a by a lot).

  • Flat earthers and science deniers?

    Can we agree that they are "DELUSIONAL"? And those which I consider the most or more delusional (by far) are the liberal socialist progressive intolerant leftists. Basic logic escapes them. So is it FAIR to say that the FLAT earthers and science deniers are, in fact, the LEFTISTS?

  • When does observation become theory?

    Best answer: If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon. ... Tanner likens theories to a basket in which scientists keep facts and observations that they find.

  • How can you determine the exact time to set your watch by if....?

    All of humanity has ceased to exist, all clocks and time measuring devices have stopped working. How would you decide what to set your watch to (assuming you don't have other priorities?).
