1) name three traits common to all arachnids (insects) does not have to be scientific. ie: all have antennaes.
2) state why behavioral traits, such as "preys on small insects" or "spins intricate web," would not be apporpriate for many dichotomous keys. when might such trait help identify an organism?
3) how is "dichotomous" an appropriate word to describe keys you used and constructed in this lab.
4) how is the construction of a key different from the construction of classification system.

I could answer this, but then I looked at the questions and how they were worded in comparison to yours.
Do your own homework.

Arachnids have book lungs, simple circulatory structure. They also have an exoskeleton. The are segmented and differentiated Body aka thorax and all that good stuff. They are ceolomates containing better specialized tissue. The anthropods in general can be classified based on appendage (again look at the millipeade a class of arthropods based on appendage and number of legs).. by the way just finished this chapter in school and did a report on it.

arachnids are spiders, not insects. Do the rest of the questions refer to spiders or insects?

Do you own homework. For Gosh sakes, you live in the era of Wikipedia. It's easier than ever.

THIS IS YOUR BIOLOGY TEACHER SPEAKING: An arachnid is not an insect!
SURPRISE!
I suggest you open your book and read! Failing that, please listen better in class.
