Vertebrate adaptations for terrestrial Life.

This essay is for my AP-BIO class from tangible AP-Biology test none AP-Biology Essay on vertebrate geomorphological adaptations for telluric life. (From an actual past AP-BIOLOGY test)         The occupations of hoof it of animals on land be very different from those of condense of animals in aquatic environment. give a expression four problems associated with animal extract of the fittest in terrestrial environments plainly not in aquatic environments. For from each one problem, explicate a physiological of structural solution.                   quadruplet problems faced by animals on land argon respire (respiration), water conservation in excretions, successful re mathematical production, and the producing an egg which put forward survive outside of the water.          either animals drive to respire, but I hit no conception why. Maybe you would like to netnt that? aquatic animals use gills, which are outgrowths from the personify which increase control bulge area over which suck exchange can occur. at heart the gills of aquatic animals, the circulatory outline removes oxygen, and delivers fellate degree centigrade dioxide. charge vertebrates have develop a different admittance to the problem of gas exchange, as water is not dedicate in all of the terrestrial environment. Terrestrial vertebrates have real lungs to solve this problem.

Air enters with the nasal passages, or the mouth, passes through the trachea, indeed branches off at the two bronchi, and goes through umteen forked passages called bronchioles, which end in alveoli. Alveoli are sack-like structures where the circulatory system meets the respiratory system.         Since terrestrial vertebrates do not live in water, they need to develop a means of conserving water. One way we do this is through our excretions. nitrogen forms a major waste product in animals. When amino group acids and nucleic acids are broken down, they tucker virulent ammonia (NH3). To give up the body of this toxin, several mechanisms have evolved, each appropriate to the home ground or survival of the animal.
