Their lungs improved and their skeletons became heavier and stronger, better able to cope with the increased gravitational effect of life on land.

Their large lungs have adapted to permit rapid exchange of oxygen and to avoid trapping gases during deep dives.

Their lungs are highly vascularized to facilitate gas exchange.

Their lungs become fully developed, allowing for a fully terrestrial existence.

Their metamorphosis from the larval stage is incomplete, so that the adults retain gill slits ( although they also have lungs ), and lack eyelids.

Their father, Philip, the driver of the Previa, was taken to the University Hospital of North Staffordshire with fractures to the neck, back, ribs and swelling of the lungs ; while a 49-year-old man and his two sons, aged eight and fifteen, were treated for minor injuries.

Their faces are stained by the hue of a green oxygenated liquid, which is believed to cushion their lungs against the extreme acceleration of interstellar flight ; this liquid is contained in their helmets.

Their defining characteristics are their extra vertebrae ( bringing the total to nine ) and the remains of the tail muscles ( the tail itself is absent in adults, although it is present in the younger frogs, who need the extra skin surface until their lungs are fully developed ).

Their lungs extract oxygen more efficiently than normal unmodified humans, allowing them to exert themselves without getting short of breath, or function at high altitudes.

" Their classification of Katrina's death as a possible accidental drowning seems to confirm that ; having been dead for perhaps a half hour or more before Spike put her in the river, Katrina could not have had any water in her lungs to support a diagnosis of drowning, and a coroner could probably have determined that she suffered the actual cause of death, a blunt blow to the head, prior to immersion.

Their skeletons changed so that their limbs were more flexible ( they became less laterally splayed, allowing for faster forward motion ) and they developed a shorter ribcage and larger lungs to allow for faster respiration.

Their consequences are irrelevant -- or there are no consequences at all.

Defoe then commented, `` If they Could Draw that young Gentleman into Their Measures They would show themselves quickly, for they are not asham'd to Say They want only a head to Make a beginning ''.

Their expressed standards concerning sex roles, desirable age for marriage, characteristics of an ideal mate, number of children desired are congruent with the values and stereotypes of the preceding generation -- minus compulsive rebellion.

Their commitments are, for the most part, couched in a familiar idiom.

Their conclusions concerning the untrustworthiness of the West Saxon annals, the confused chronology of Bede, the unreliability of the early positions of the Anglo-Saxon genealogies and the mythological elements contained in Nennius are now mostly accepted.

Their privations are almost beyond endurance.

Their national leader, Robert Bolivar DePugh of Norborne, Mo., says the Minutemen believe that guerrilla tactics are best suited to defeat the Red onslaught.

Their United States tax returns are due April 16, 1962.

Their locations in all parts of the United States, and their locations in the several kinds of educational and research institutions that are the principal homes of our intellectual and artistic strengths also are factors in the Trustees' minds.

Their friends and ours are welcome to share the pool, but on our terms and at our times.

Their experience is quite in contrast with that of children of upper- and upper-middle-class native-born parents, who are more likely to regard education as good for its own sake and to discount the vocational emphases in the curriculum.

Their effects are only superficially startling.

Their names are Mantle and Maris, their team is the Yankees, and their threat is real.

Their autumn tints are all fairly low keyed compared with the fiery stabs of crimson, gold, purple, bronze, blue and vermilion that flame up in North America.

Their metabolic rate is low and as a result, their food and energy requirements are limited.

Their ribs are usually short and may be fused to the vertebrae.

Their skulls are mostly broad and short and are often incompletely ossified.

Their gills are never covered by gill sacs and are reabsorbed just before the animals leave the water.

Their leaves are of variable size and alternately arranged, or alternate with the upper leaves becoming nearly opposite.

Their beliefs and behavior are difficult to decipher from physical materials, and their languages remain unknown as they had no known writing system.

Their new style of psychology, later dubbed functional psychology, had a practical emphasis on action and application.

Their relative simplicity makes gene loss-of-function experiments in C. elegans the easiest of all animal models, and thus, scientists have been able to knock down 86 % of the ~ 20, 000 genes in the worm, establishing a functional role for 9 % of the genome.

Their foundations are distinct models of computation: Turing machine for object-oriented and imperative programming, lambda calculus for functional programmming, and first order logic for logic programming.

Their high degree of functional plasticity and the extraordinary density of their interconnections enables neuronal groups to self-organise into many complex and adaptable " modules ".

Their powerful legs end in four sharp talons that can unlock and fold back to reveal another pair of functional hands.

Their independence decreased significantly as the Kombinate became fully functional.

Their results shed new light on the functional role of the motor system in encoding visually presented objects.

Their strongly functional and undecorated forms have however been highly regarded by designers and collectors.

Their positioning therefore is more likely symbolic rather than functional.

Their eyes are yellow, with epicanthic folds and a functional nictitating membrane to protect them against wind-blown grit.

Their work is supported by regular, functional meetings of officials, including the G7 Finance disputes.

Their review of a wealth of data from functional imaging ( functional magnetic resonance imaging and positron emission tomography ) and structural imaging ( diffusion MRI, voxel-based morphometry, in vivo magnetic resonance spectroscopy ) argues that that human intelligence arises from a distributed and integrated neural network comprising brain regions in the frontal and parietal lobes.

Their modern counterparts consist more likely of bricks or blocks of various materials, stucco, or even simple studwall framing, with a look-alike " frame " of thin boards added on the outside to mimic the earlier functional and structural weight-bearing heavy timbers.

Their functional roles are non-image-forming and fundamentally different from those of pattern vision ; they provide a stable representation of ambient light intensity.

Their simple, functional designs chimed in with the modernist ethos.
