What is the spider web an example of
The correct option is A True
Spider web is an example of radial symmetry.
What are webs made by spiders
silk
Spiders make their webs from silk, a natural fibre made of protein. Not only does spider silk combine the useful properties of high tensile strength and extensibility, it can be beautiful in its own right. Jan says, 'Silk is an amazing material.
Why is web making an innate behavior
Instinct is a type of animal behaviour that need not be learned. A spider does not learn how to spin its web. It is born with the knowledge of web spinning. So, it is an instinctual behaviour.
What is a spider web pattern
Spider web can take a variety of forms, but the most common type is the Orb web. The gradations of the web patterns can be written in the following order: Orb web > Sheet web > Irregular web > Funnel web > Single line snare web > Horizontal dome shape web.
Is spider web an example of structure of protein
Spider silk is one outstanding fibrous biomaterial which consists almost entirely of large proteins. Silk fibers have tensile strengths comparable to steel and some silks are nearly as elastic as rubber on a weight to weight basis.
Is spider web a symmetry
Spider web is an example of radial symmetry.
Why are spider webs made
Spiders rebuild their webs by eating the silk then "recycling" it to make new webs. Webs have multiple purposes, but the most important one is to trap insects for food. Webs are also used for: Travel or "balloon" from one place to another.
What protein is a spider web made of
Spider silk primarily consists of proteins that possess large quantities of nonpolar and hydrophobic amino acids like glycine or alanine, but for example, no or only very little tryptophan. In comparison to common cellular enzymes, it is evident that silk proteins exhibit a quite aberrant amino acid composition (Fig.
What is an innate behavior of a spider
They don't need to learn how to hunt. Spiders spin their complex webs without learning how to do it from other spiders. Birds and wasps know how to build nests without being taught. These behaviors are called innate.
What is innate behavior examples
Innate behavior comes from an animal's heredity. An animal's instincts are examples of its innate behavior. For example, migrating birds use innate behavior to know when to begin their migration and the route that they should follow. Learned behavior comes from watching other animals and from life experiences.
Is spider web a symmetry pattern
Radial Symmetry – Spider web – scientist believe that the orb web spider builds nearly perfect circular webs with almost equi-distance radial supports for strength.
Is a spider web a shell or frame structure
A frame structure consists of different parts. These parts are combined in such a way to make the structure strong. A ladder and a bicycle are good examples of man-made frame structures. Spiderwebs are natural frame structures.
What type of frame structure is a spider web
Indeed, the orb web is typically composed of compliant adhesive spiral threads, the main function of which is prey retention, supported by a scaffold made of strong and rather stiff major ampullate threads (mooring, frame and radii) keeping the sticky silk in place, dissipating the prey energy and transmitting the …
What type of symmetry is spider
bilaterally symmetrical
Spiders have bilaterally symmetrical bodies. Bilateral symmetry refers to the body shapes that can be divided into two perfect halves along a midline known as the sagittal plane.
Is spider web a spiral pattern
The web of spiders is composed of radial and spiral threads each with their own characteristics. Spider webs are a distinctive example of high-performance bio-material design in Nature.
Why do spiders make silk webs
Spider silk is one of the most versatile materials on Earth. Actually a protein created by special organs known as spinnerets, spider silk can be used for transportation, shelter, courtship, and all kinds of creative ways to trap prey. Some spiders can produce more than one type of silk.
What are spiders made of
Like other arthropods, the spider's body is covered with a more or less rigid 'skin' or cuticle (the exoskeleton) made of protein and chitin. The spider cuticle consists of several layers, the outermost being toughest, covered with a thin surface wax layer that helps reduce water loss from the body.
Are spiders a source of protein
Today, spiders — rich in protein, folic acid and zinc — are considered a delicacy and sold in markets and restaurants across Cambodia.
Is spider web a polymer
Spider silk is a natural polymeric fiber with high tensile strength, toughness, and has distinct thermal, optical, and biocompatible properties.
Is a spider spinning a web a behavioral adaptation
Behavioral Adaptations
Yes, spiders can actually adapt their web-building techniques to the environments they live in.
What is an example of innate behavior
Innate behavior comes from an animal's heredity. An animal's instincts are examples of its innate behavior. For example, migrating birds use innate behavior to know when to begin their migration and the route that they should follow. Learned behavior comes from watching other animals and from life experiences.
What are two examples of innate behavior in animals
The following behaviors are examples of innate behaviors:Web making in spiders.Nest building in birds.Fighting among male stickleback fish.Cocoon spinning in insects such as moths.Swimming in dolphins and other aquatic species.
What is a real life example of innate
Innate behavior is behavior that's genetically hardwired in an organism and can be performed in response to a cue without prior experience. Reflex actions, such as the knee-jerk reflex tested by doctors and the sucking reflex of human infants, are very simple innate behaviors.
Is a spider web a natural structure
Apart from the remarkable material properties of spider silk, spider webs are natural example of a special class of prestressed systems called tensegrity (tensional integrity) structures (Motro, 1992).
Is a spider web a symmetrical pattern
Like most of nature's constructs, a spider web shows departures from one having perfect radial and angular symmetry. This fact does not, however, detract from the fact that they work quite effectively.
