Molting, or in Latin, ecdysis (meaning 'to strip'!).

The arthropods body detaches from exoskeleton?
Yes, in arthropods the exoskeleton detaches during moulting, and is completely shed in order for the organism to increase in size. After a while the new, softer skin hardens.
What does an arthropod molt?
Yes, arthropods have to moult in order to increase in size, because their exoskeleton is rigid and inhibits growth. The process is called ecdysis and is not limited only to arthropods; it is a characteristic of their clade, ecdysozoa, which includes nematodes and other phyla. Arthropods are more vulnerable when moulting because their new exoskeleton is soft and therefore more vulnerable to predators. The new exoskeleton takes a while to harden; many will hide and wait during this time. Arthropods will usually moult multiple times during their lifespan; the process is also associated with lost limb regrowth.
Is the exoskeleton of the arthropod shed during molting?
Most only do so in larval/juvenile stages, when it's time to grow. Some arthropods such as tarantula females continue growing and molting until death. Also, when damage has occurred (torn off leg for example) molting can be induced earlier to develop and grow new appendages. :)
How do Arthropods (Crustaceans) eat?
Since arthropods have a rigid exoskeleton, in order to grow they need to moult their entire skin, then wait for the new exoskeleton to harden. Some of them eat the old exoskeleton in order to recapture the mineral content. Since many (like the crustaceans) are vulnerable during this stage, they need to hide for a while. The moulting process for some arthropods also integrates with the limb regeneration function.
What happens to arthropods during molting?
When it grows to big for its exoskeleton, like a hermit crab.
How do arthropods grow?

Are arthropods skin soft?
Generally arthropod skin is not soft; arthropods rely upon their exoskeleton for structural support (and for protection) and as such it usually need to be tough. Crustaceans further harden it with calcium carbonate via biomineralization. Since arthropods need to periodically moult (ecdysis) they go through cycles of soft exoskeletons in order to grow during the moult; the new "skin" hardens and expand with time, and during this period they usually hide, owing to their increased vulnerability.
What is the function of molting?
When arthropods outgrow their exoskeletons, they undergo periods of molting. During molting, an arthropod sheds its entire exoskeleton and manufactures a larger one to take the smaller ones place. Molting is controlled by the arthropods endocrine system. An animals endocrine system regulates body processes by means of chemicals called hormones. As the time of molting approaches skin glanes digest the old part of the exoskeleton and other glands secrete a new skeleton. Whenthe new skeleton is ready the animal pulls itself out of what remains of the original Skelton, this process can take several hours while the new exoskeleton is still soft the animal fills with air or fluids to allow room for growth before the next molting. Most arthropods molt several times between hatching in adulthood. This process is dangerous to the animal because it is vonerable to preditors while their shell is too soft to protect themselves. Most arthropods like to hide during molting or molt at night when less predictors can get them.
What problems does an exoskeleton cause an arthropod?
I hope this helps (indirect problems) Exoskeleton usually don't cause arthropods problems except when they're growing. Arthropod are like snakes the must break out of their shell in order to grow bigger. When arthropods break out of their shell they must wait until the new skin hardens and becomes a shell again. During this time most arthropods vulnerable to prey due to the lack of protection from their shell Another problem would be the size of a crevice or hole when fleeing predators. If at the time of attack by a predator , the rigidity of the outer shell limits the size of the shelter to escape to.
Why is molting necessary for arthropod growth?
Because of the composition of the exoskeleton. It must of necessity be tough to serve its function. Since it is inflexible, the organism has to periodically shed it (moult) in order to grow; a process called ecdysis.
Why the dogs loses its coat?
It is called shedding. This naturally occurs especially during the summer time to keep the dog cool.
Why are jointed appendages considered an important adaptation during the evolution of arthopods?
The primary adaptation of an arthropod is not the jointed appendage, funnily enough it's what covers the rest of it. Chiten, the hard exoskeleton of arthropods allowed them to evolve in millions of different shapes and forms, while at the same time providing a protective armour casing. Ever wonder why the insect life was not affeced by Chernobyll, or why a crayfish doesn't cook in a microwave? The exoskeleton in Arthropods is the key to their success - they, along with other invertebrates, take up 75% of all life on the planet.
