Biology

The Phylum Arthropoda were the first animals to merge on the land. The adaptations that allowed this consisted of their chitonous exoskeleton and flight pronounce in the level Insecta. Their chitonous exoskeleton allowed the bar of desiccation, which caused the respiratory system to be en closed(a). With the respiratory system being enclosed it helps prevent diffusion. The legal profession of desiccation was the more master(prenominal) of the two overall functions that the chitonous exoskeleton provides. The split reciprocal ohm function the chitonous exoskeleton provides, is the ability to overcome gravity. The chitin-based exoskeleton allows for muscle attachment and for mundane species it prevents desiccation as previously stated. The exoskeleton provides protection against predators and helps prevent establish exit. Because of these adaptations the arthropods had to acquire, it meant they had to change their ways of breathing. Arthropods have gills or other respiratory structures located inside the body. This location minifyd piss loss when definite groups moved onto land. Insects evolved a waxy layer to minimize water loss from the body surface, with openings to respiratory passages that can be closed if the environment dries (Freeman 2011).

Arthropods jointed limbs made it possible for rapid, punctilious walking, trial and jumping movement. The jointed limb is a major dry land this phylum has been so successful in terms of diversity, teemingness of individuals, geographical range, and duration in the fossil record (Freeman 2011). In the Class Insecta, the insect wing is one of the most important adaptations in the! history of life. About two-thirds of the multicellular species living now are winged insects (Freeman 2011). The adaptations called for a tracheal system so that they were able to croak around the limitations of the open circulatory system, which as surface as caused the sense organs to be very developed. on a lower floor the Phylum Chordata, search developed jaws.
