okay, it's time for YOU to look up your answers in the book and get some studying done. We're not here to get your homework done.

Nobody really knows. One explanation is that oxygen levels in the atmosphere were higher in the past for reasons we don't understand. That is supported to some degree by isotope ratios in rocks. With higher oxygen levels insects could grow larger without running into problems of gas diffusion.\n\nThe other hypothesis is that the greenhouse world that existed when the giant insects did was incredibly productive and allowed for extravagant solutions that would  not be energetically feasible today. For example insects today can achieve limited active respiration by pumping their abdomens  but it is amazingly wasteful of energy. However in world with limitless food that may not have been limiting. That theory is supported to some degree by the fact that the giant insect fossils only turn up in the equivalent of rainforest locales, IOW in the most productive areas of the planet.\n\nIt is worth noting that the giant insects seem to have come and gone at least twice. They were common in the Carboniferous and then died out and re-emerged around the Silurian. That suggests that whatever was limiting them was somehow recurring.

One answer might be that they have gradually changed, or evolved,over a very long time to suit the places they live in and the food that is available to them.\n                 In the 19th centurya scientist named CHARLES DARWIN (1802-1882) put forward a theory, which he called 'natural selection'. to explain how these changes might happen.\n              According to darwon, individuals animals and plants sometimes have qualities that help them to survive.For example,in agreen forest, a green bug would pribably survive longer than a brown bug,because its appearence would help it to aviod being seen amd eaten.\n       The individuals that survive the longest are likely to have more babies,and will pass on their useful qualities to them.Over a very long time,each species will very gradually develop all the most useful qualities for surviving in its own habitat.

Insects are all hexapods.  Other arthropods have more legs, that's the essential.  If it has more than 6 legs, it's not an insect.  Spiders are not insects.

Its called Ecdysis.Ecdysis is the moulting of the cuticle or the exoskeleton.Higher insects have only 4-5 moultings whereas lower insects have till 15.As the exoskeleton is hard its difficult for the insect to grow so it moults periodically to grow.They grow a new exoskeleton later.

Adaptation? Evolution?

The incorrect answer is C. Spiders will NOT accept dead insects. They only eat the fresh ones (otherwise we'd have a lot less dead insects around).\n\nHope this has helped you!

every insect has 6 legs, so all bees, ants, wasps, flies, flees...also scarabs have 6 (cocroaches and beetles) \nthe only creepy crawlies with more legs are archnides: basicaly spiders and scorpions (which have 8), or millipedes (which have loads)\nthe simple rule though is that if it flies it has 6 legs

google it..type in scientific insect names. That always helps. OR type in the name of the insect, and all sorts of stuff should pop up

No. All insects have an exoskeleton, a hard covering or special skin (cuticle), which provides support and protects them from water loss. Because of their high surface to volume ratio, insects have the potential to lose water rapidly. The hard cuticle is coated with waxes (long chain hydrocarbons similar to those found in beeswax) which minimizes water loss.

Accident. Coincidence. Chance. These shaped the universe as we know it. Organisms have slowly evolved and become humans as we are today... And we've stopped evolving almost completely because we've learned that, rather than adapting to our environments, we can adapt our environments to US. We no longer need changing survival skills for heat or food, because these are grown and raised and manufactured for us... and this will probably be our eventual downfall. If ever we are failed by technology, our inability to adapt and grow and evolve will cause us all to perish.
