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.

oxygen is the first element in group 16 (via) of the periodic table. the periodic table is a chart that shows how chemical elements are related to each other. the elements in group 16 are said to belong to the chalcogen family. other elements in this group include  sulfur, selenium, tellurium,  and  polonium.  the name chalcogen comes from the greek word  chalkos,  meaning "ore." the first two members of the family, oxygen and sulfur, are found in most ores.

oxygen is by far the most abundant element in the earth's crust. nearly half of all the atoms in the earth are oxygen atoms. oxygen also makes up about one-fifth of the earth's atmosphere. nearly 90 percent of the weight of the oceans is due to oxygen. in addition, oxygen is thought to be the third most abundant element in the universe and in the solar system.
