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 hail a line in the track Insecta. Their chitonous exoskeleton allowed the bar of desiccation, which caused the respiratory system to be en unappealing. With the respiratory system being enclosed it helps prevent diffusion. The legal community of desiccation was the more master(prenominal) of the two overall functions that the chitonous exoskeleton provides. The split bet on function the chitonous exoskeleton provides, is the ability to overcome gravity. The chitin-based exoskeleton allows for muscle attachment and for terrene species it prevents desiccation as previously stated. The exoskeleton provides protection against predators and helps prevent pissing 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 stru ctures located inside the body. This location minifyd pee loss when indisput up to(p) 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, running game and jumping movement. The jointed limb is a major campaign 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 adaptatio! ns in the history of life. About two-thirds of the multicellular species living now argon winged insects (Freeman 2011). The adaptations called for a tracheal system so that they were able to get around the limitations of the open circulatory system, which as easily as caused the sense organs to be very developed. to a lower place the Phylum Chordata, search developed jaws.
