Why Does A Bee Die When It Stings?

Why Does A Bee Die When It Stings?
When a bee stings, barbs contained by the lance of the sting motive it to firmly stick into the victim pulling out the toxin sacs and glands when the bee is shaken bad.
The venom sac muscles verbs to pump after these organs have be torn from the dying bee. Only the female workers and the queen can sting, the queen have a smooth sting which she uses to kill other queens..
It's stinger pulls out when it stings . it have a barb on it.
coz the stinger is atached inside to its guts
and it rips its guts out
if u r talking within case of humans consequently i think human blood is more poisionous later the sting of bee.
ha!ha!ha!
What else does he have to do after that?

Why does a bed get the impression slippery when it comes into contact beside your skin?

Why does a bed get the impression slippery when it comes into contact beside your skin?
Probably From the Formation of a Soap. I Like grimmyTea's Answer.
A base what? Sorry, your put somebody through the mill isn't clear.
Your skin has tubby in it. What do you catch when you mix lye (sodium hydroxide) with round? You get soap.
The chemical process is call saponification. Remember that a basic chubby molecule is composed of three fatty acid chains esterified to a glycerol molecule. The hydroxide molecules hydrolyze the ester bonds and you are departed with glycerol plus free fatty bitter chains and Na. You can precipitate the sodium + fatty acids as a salt -- which is how empire make homemade bar of soap.
Maybe a more interesting question is why soap is slippery? I'm truly not sure about that. I would guess it have something to do with the fatty sharp chains lining up to engineer a nonpolar barrier between the surface of your skin and anything you are touching (sort of like a nonstick surface). Don't quote me on that though.
Bases are used to fashion soap. This is the reaction of floor + fat--->soap and glycerine . But back to your examine, it is a physical property of bases. But cogitate of soap and try not to get it on your skin, as it is penetrating.
I think a groundwork is good at hydrolyzing and dissolving proteins, resembling the ones in your skin. It may also take action with podgy and oil on your skin to create a soap close to molecule that has slippery fatty acids . Lye and corpulent is the original formula for soap.

Why Doctors work is call PRACTICE ?

Why Doctors work is call PRACTICE ?
A definition of practice is "to be professionally involved in". So there's no stretching of the word or anything. Its just a different definition than the commonly used "to carry out work repetitively so as to become proficient."
maybe coz they practice prescription??
it doesn't mean they are practicing close to practicing baseball before a spectator sport, it means they do it for a living.
Note: It is Practice not practise. Get it right.
Because they're trying to bring back better at it. They are lucky in that they can bury any mistakes they put together while they are still learning.
Why is a shop call a shop?? its just the cross of the place in which they work, thats adjectives. No specific reason why.
Cause they similar to to practice on their patients
Not only doctors use that word practice for their profession. But also accountants, lawyer, architects, engineers. It's just my two cents worth---because while within school, they revise all the theories, and when they work, they achieve to apply, or practice the theories that they learned.
One daytime they might get accurate at it
It is because they do not know what they are doing half the time and they revise on the job a large amount - you know the score; "try these pills for a week and if you are no better come backbone and see me again"
Because they 'practice' medicine
If you enjoy a GP like mine you would know everything he does is in recent times practice,if smoking drinking and eating red meat is not the create he as a problem.
It is derived from Latin and Greek "praxis", meaning practical application or exercise of a branch of research.
That seems entirely appropriate and accurate.

    why doctors don't donate their blood during blood drive?
    They think their blood is royal blood and not worthy of person placed in mere mortals.
    I wonder this as economically. I guess they are fear to do that.
    I go for a body check and the doctor didn't told me it was time for injection. I be so shocked when he took out his injector. Then my blood was sent to the center for donation.
    they do. you freshly don't see them because they are tending to customers such as yourself.
    Many do, but oodles can't take that much time away from their duties to sit within the blood drive for an hour and a half surrounded by the middle of the workday. Also, many doctors and medical students enjoy been out of the country on outreach trips, and they won't filch your blood if you've recently be to certain parts of mexico, south america, africa, india, or asia.
    We don't donate for several reason. First, we are generally not within a position where we can be tied down near a needle within our arm. Example, what would happen if someone "coded" while the doctor be donating blood. Also, we are around potentially infectious people adjectives day everyday. We never know if we own contracted something and certainly do not want to pass by that on through blood donations
    you're asking a loaded question that isn't base on any kind of certainty or study that actually suggests that doctors don't donate blood or donate blood smaller quantity than the average person.
    however, if i have to take a guess, it could be that they can't afford to lose blood (and hence be tired for a few hours) if they're working long hours. aside from that, it could newly be that they have other things they want to do near life, only like anyone else.

    why do your eyes enjoy to be closed surrounded by lay down to sleep?

    why do your eyes enjoy to be closed surrounded by lay down to sleep?
    they don't, but it is generally easier to rest when brain does not hold to process the visual input from eyes
    They don't, but to sleep your brain have to produce melotonin, which is only produced when within is very little wishy-washy in the room. It's also tricky for the brain to make melotonin if it have to process images from the eyes at one and the same time.
    To keep them moist and protect the eyeballs. If you slept and yours eyes stayed initiate the air would dry them and bits from your bedding would bring back into them as there would be no protection and you would finish up with eye infections.
    Rapid Eye Movement. REM Sleep cause the eyes to twitch and this is a part of Melatonin formation surrounded by the PONS of the Brain. It is activated within a Dark Enviroment. This is why our eyes are closed and it is a reflex so we do not damage our eyes during sleep or or lower consciousness. Herbert West III west.herb@yahoo.com
    You don't own to sleep with your eyes closed, but your MOIST eyeballs prefer it.

    why do you regard as the details of skeletal muscle and cardiac muscle contraction.?

    why do you think the details of skeletal muscle and cardiac muscle contraction are justly well embedded, but knowledge of contaction of smooth muscle is more constrained?why do you regard as the details of skeletal muscle and cardiac muscle contraction.?
    All of the above are well couched, it's just that skeletal and cardiac mucsle are more complicated, so there is more information on them. Smooth muscle contraction can function solely on its intrinsic plexus, its built-in on edge system that only receive fine tuning from the para and sympathetic nervous systems. It even have its own immune system, Peyer's Patches for example.

    why do you see your breathe on a cold afternoon?

    hurry please and thx you!!why do you see your breathe on a cold afternoon?
    The water vapor within your breath condenses when it hits the cold air and make a small cloud in front of you.
    cuz its cold!
    Because it heat up the moisture in the heavens, turning it into steam.
    Your breath is hot (98.6) and moist (100% humidity). When it hits the cold air your breath cools below the condensation point and the wet vapor in your breath condenses into droplets which you see as steam.
    The moisture contained by your breath.
    Your exhaled breathe contains a lot of thaw out water vapor, and when it hits cold nouns, the temperature drops below the point where on earth it can hold that much water, so some of it condenses contained by front of your face.
    because within cold, the tempreture outside the body is LESS then inside the body
    (as we know at low tempreture, gas converted into a juice due to condensation)
    Your breath has marine vapour and this spray when go to a cold medium will condensed as a fluid which you can see it
    (Fluid has a gas and juice properties)
