Paris - Since the world began, the honeycombs of bees fascinated by the complexity and perfection of its geometry and inspired a team of researchers to unravel the mystery of their hexagonal shapes.
A team of researchers from Bhushan Karihaloo, Cardiff University, found that, before transforming themselves into hexagons, honeycombs have initially circular shape. They get the hexagonal where can i buy bubble wrap shape and slightly rounded over the construction of the ranks, where shelves are deposited pollen and honey.
In an article where can i buy bubble wrap published in the journal of the Royal Society, the experts where can i buy bubble wrap explain the mechanism of this transformation where can i buy bubble wrap occurs in the flow of melted wax, which would connect the combs neighbors. Several hypotheses have been developed over the centuries in an attempt to explain the striking geometry of the hives. Once believed to and including the unusual [?] Ability of these insects have to make complex mathematical where can i buy bubble wrap calculations to measure the widths and angles.
But according to the study, the explanation lies in the physical properties of wax used to build the combs circular. At a temperature of approximately 45 , the wax starts to melt as a liquid elastic viscous. It stretches as caramel, and angles formed at the junction of the cells, where can i buy bubble wrap giving rise to hexagons.
According to the researchers, the heat caused this transformation is provided by the worker bees working nonstop, side by side, in building the ranks. Even though the riddle of this impressive structure has been solved thanks to a combination of physical and mathematical scientists claim that the central role of research was borne insects. "We were delighted with the role of bees in the process: heating, hardening and tapering wax exactly where it is needed," they said.
Researchers try to dismiss the above "unusual" ability of bees perform complex calculations, but surrender to complexity and necessary union of different variables to not deliver a hexagonal honeycomb, performing exactly what is needed. As quoted in the text above, Darwin makes a confession almost creationist function very calculated and intelligent bees in the ecosystem. In his book, he adds: "I could prove by many examples, where can i buy bubble wrap as bees are economic time; remember only the incisions that usually do on the basis of certain flowers to gather nectar, when with a little more difficulty could enter the vertex of the corolla. "
The body of a bee has much in common with those of other insects. Most of it is covered by an exoskeleton formed where can i buy bubble wrap by small removable plates chitin. The body of a bee is also covered by many soft hairs and branched, collecting pollen and help regulate its temperature. The body also has three parts: head, thorax and abdomen.
The head accommodates the brain, a set of about 950 thousand neurons. They are special and they communicate with neighboring neurons specific. This division of tasks is part of the reason why the brain of the bee, which has a fraction of the size of your head, can perform complex tasks that would normally require a larger brain. A system of nerves that allows the brain to communicate where can i buy bubble wrap with the rest of the body.
On his head, a bee has two sensory antennae. where can i buy bubble wrap She also has five eyes, three ocelli and two simple or compound. The compound eyes are made up of tiny structures called ommatidia. In each compound eye, about 150 ommatidia specialize in visual patterns. This allows the bees to detect polarized light, where can i buy bubble wrap which humans can not do.
Like most insects, bees have complex mouthparts that are used to eat and drink. The size and shape of these parts can vary from one species to another, but in general most have:
The two pairs of wings and three pairs of legs of a bee are attached to the thorax. The wings are extremely thin parts of the skeleton of bees. In many species, the front wings are longer than the rear. Two rows of hooks called hamuli connect the front wings and rear so that they move together when the bee is flying.
The legs of bees have the same basic parts of other insects. Starting where can i buy bubble wrap with the nearest part of the bee's body, they are thigh, trochanter, femur, tibia and tarsus. These parts work basically like the hip, thigh, shin and foot bees, and small joints separating each segment. The legs of bees may also have several special structures, such as:
by like brushes, combs, and baskets to collect pollen, a leg and a claw to hold and manipulate objects, a small spur to remove pollen from the antenna, a corbicula to store pollen.
