Research Project: Class Insecta Insects are invertebrates in the class Insecta from the phylum arthopoda. Arthropods include more than 850‚000 species and form by far the largest phylum in the animal kingdom‚ exceeding in number all the other Phyla combined. The characteristic tough exoskeleton and jointed limbs are superimposed in a segmental body plan that reflects the evolution of arthropods from ancestors of the annelid worm.

I fear the room because it has a decent amount of old stuff‚ the room is dusty‚ and it is a dwelling for many arthropods and arachnids.

The history of the Earth is categorized into four different geological time eras beginning with‚ the Precambrian Time (4.6 billion-544 million years ago)‚ the Paleozoic Era (544-248 million years ago)‚ the Mesozoic Era (248-65 million years ago)‚ and the Cenozoic Era (65 million years ago to the present). Eras are broken down further into smaller units called periods‚ which help scientists detect changes in Earth’s history. Geologists’s main sources of evidence for geological eras‚ and periods are

areas‚ rather than rural‚ unpopulated regions. The dengue virus is passed to humans exclusively by the bite of mosquito in search of a blood meal. This mode of transmission makes the dengue virus an arbovirus (that is‚ one that is transmitted by an arthropod). Studies have demonstrated that some species of monkey can harbor the virus. Thus‚ monkeys may serve as a reservoir of the virus. Mosquitoes who bite the monkey may acquire the virus and subsequently transfer the virus to humans. The disease has
