What is the function of the proventriculus?

The proventriculus is a glandular part of the stomach that stores and starts to digest food before it enters the gizzard.

They convert inorganic material to organic ones to make the soil fartile. This is done due to their living and it also helps in living the plants... both way benefecial :)

Il est possible que la taille du sabot a été mal faite, ce qui donne au pied un mauvais angle. Cet angle doit être mesuré par le maréchal-ferrant à chaque fois. Par exemple, un cheval ferré avec un mauvais angle pourrait ressembler à faire marcher quelqu'un 24h/24 avec des talons hauts. À un moment donné, ça cause des douleurs dans les muscles et les tendons. Ça peut aussi être dû à un fer trop serré...pas assez large, ce qui comprime le pied. C'est un peu comme marcher dans des souliers d'un point plus petit que notre pointure normale. Ça peut aussi être dû à un clou mal placé...mais bon, quand un cheval se fait poser un clou dans la chair, en général, il réagit tout de suite parce que ça lui fait mal et le forgeron le détecte tout de suite. À ta place, je ferais vérifier le ferrage de ton cheval par ton forgeron. Bonne chance.

Its a mechanical device basically used for turning ,tapering of metal,wooden jobs.It can also be used for threading ,offset turning ,boring and drilling of jobs.

l'angle de 35° par rapport à celui de 45 favorise un meilleur plané du javelot par une pente plus douce. d'autre part au niveau anatomique  ou plutôt biomécanique un lancer à 45° efficace nécessiterait trop de contrainte en terme de position et par conséquent ne permettrait pas une bonne production de la force musculaire

Support of the head, as in all animals. Sometimes the atlas and axis are fused but in turtles is allows for their head to stick out like it does. The head is slightly above the spine alignment and these two bones allows for that.

The mitrochondrion is the powerhouse of the cell, or the battery that gives it the energy it needs. Hope this helps.

Like many parts of our body, it serves more than one purpose.  Two I can think of: 1) it is an opening that can close securely enough to protect the anus yet open enough to allow poop to come out and 2) yes, it seamlessly continues the leg, making it very easy to stride and open our legs wide for many functions.

I would look here for your answer and/or a link that could get you your answer http://en.wikipedia.org/wiki/Vertebrate\n\nGood Luck!!!

Generally, the force is applied at the point of "input force" - that point is determined by what class of lever you're using.\n\nFor example, if you're using scissors (First class lever), the fulcrum is at the pivot between the two handles and blades, the input force is at the handle, and the output force is on the blade.\n\nIf you're using, say, a wheelbarrow (2nd class lever), the fulcrum is at the wheel, the input is on the handle (end), and the output force is in the middle - in the bucket.\n\nFor a baseball bat (third class levers), the input force is in the middle (your hands), fulcrum at one end (you), and the output force is at the other end (the end of the bat).

Well, Presently no functions are established. The theories about its unctions are there. It is said that it was functional once when human skills regarding obtaining food were primitive and they have to consume only vegitaton for food. The cellulose contained in this vegitation is not normally digested but when the apendex was functional its role was for digestion of cellulose and other such complex substance. With improvement in Food skills the cellulose part decreased and now we don't consumed scrub and natural selection eliminated the genes or they went dormant as 97% DNA is without known function.

I´m only gonna attemp thisbecause it´s kind of late and there´s a chance you´ll have to wait untill tomorow (and I guess you´re cramming). So if you don´t get anyother answers, pick and don´t let it go to waste)\n \nImagine you have a scalar function over R3, that is f(x,y,z). Pressure is a scalar - it is given by a number so there is no direction involved like with force.\n \nA pressure field can be defined as P = f(x,y,z) where the point (x,y,z) defines a point in space.\n \nA gradient, is a vector in space, that is, for a given point, e.g. (10, 20, 15), a gradient is a vector that could be (1, 5, -20). The thing is that the gradient points in the direction that you would have to follow if you were at (10, 20, 15) that would lead you to the maximum increase in the field (in this case, in presure). It also indicates the intensity of the increase (kind of like a derivative).\n \nAn example in the body can be given by the presure in the femur when you stand (on one leg). (These examples are acctually hard to give, because bio-mechanics is very complex; there is hidro-dinamics, flector moments etc. and few cases of hidro-statics or simple compression.) At the top end of it, it receives all the weigh of the body minus the weight of the leg. The pressure is that weight divided by the area of cross section at that point (extreme over simplification here). As you go down towards the middle of the femur, two things happen:\n1) the weight above the cross section increases;\n2) most important, the cross section reduces.\n \nSo we know that as you go down the pressure (force / area) increases. So the gradient along this part of the femur would be a vector pointing down.\n\nHope this was clear (and correct) enough.

Its not as complicated as every one else made it.\n\nSo we can move.\n\nCellulose keeps the cells ridged, with ridged cells we would have a very small range of motion.\n\nOur cells need to be able to flex and squish so we can move. If we couldn't move we would need to be able to produce our own food, like plants do, or we would need to be single celled/simple organisms like bacteria.\n\nLike two of the others said: we use our bones for structural support, so cellulose is not needed for that purpose. Why have something when you don't need it, that is what evolution is all about.

There is a weight mounted off-balance on a shaft so that it hangs down. It has a one-way ratchet connected to a reduction gear so that motion in one direction winds the spring. In the other direction the shaft just turns freely.\n\nAs you move about, walking, running, gesturing, whatever, your wrist moves back and forth. As your wrist changes position the weight causes the shaft to turn and the ratchet captures the motion to wind the main spring.
