You find a multi-legged animal in your garden and want to determine if it is a centipede or a millipede. You take the animal to a university where a myriapodologist quickly tells you that you have found a centipede. Which of the following may have allowed her to make this distinction?A) segmentationB) poisonous fangsC) egg-layingD) molting

B) poisonous fangs

Explanation:

Centipedes and millipedes are jointed legs animals. Centipedes are members of the class chilopoda and millipedes are members of the class diplopoda of the phylum Arthropoda.

Presence of poisonous fangs in the centipedes differentiate them from millipedes. Nutritionally centipedes are carnivorous, they kill prey or paralyze prey with large jaws. Unlike the centipede, millipedes are feed on dead and decaying organic matter such as leaves and compost.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
