Need help on these issues of animal?

1. How is the exoskeleton of arthropods grow like a balloon that is inflated in a can of soda? How to avoid this limitation of the exoskeleton moves? 2. How spiders digest their food outside their bodies. Why is beneficial to carry out the spiders? 3. Why a tick bite is more of a concern that the bite of most spiders is. 4. An unknown arthropod three regions of the body, a pair of antennae and three pairs of jointed legs. What kind of arthropods is it? Why?

Well, I'll try. 1) "Exoskeleton" means that the animal's skeleton is outside. Mammals (Just like humans) have a skeleton inside their body that acts as a protective cage around delicate organs. The similarity of an inflated balloon inside a soda is an illustration of the structure of the external skeleton (the drink) surrounding the inflated balloon sensitive (Creatures internal organs). When these creatures move, or shed their exoskeleton, which is part of the growth process. His new exoskeleton will be larger. 2) The spiders liquefy their food making it easier to swallow. Is not it easier for you to make a batter of a steak? The Spiders do not have teeth, so their food must be "transformed" in the first place. 3) Tick bites do not always show the same day you receive it. You do not feel a tick bite and sometimes the eruption of a tick bite may take several days to manifest. So when a tick attached to skin an animal or human, the natural reaction is to try to turn it off. It is an error because the tick's head remains on the skin, fester and lead to problems. 4) I think a lobster!
