WebChapter 43 Water Balance in Animals Water balance is closely related with sustaining a balanced concentration of electrolytes throughout the body. Electrolyte is a compound that dissociates into ions when dissolved in water. Animals produce urine to excrete waste, so this inevitably leads to water loss. The amount of water lost in the urine of an animal … Web204 Zoological Studies46(2): 203-215 (2007) as is typical of most aquatic animals. Ammonia diffusion occurs in the ambulacral feet and in the papullae of asteroids, as well as in the respiratory
Osmoregulators and Osmoconformers
WebMost marine invertebrates are osmoconformers, although their ionic composition may be different from that of seawater. Osmoregulators tightly regulate their body osmolarity, which always stays constant, and are … WebWordSense Dictionary: osmoconformation - spelling, hyphenation, synonyms, translations, meanings & definitions. freemyband.com
What is an Osmoconformer? - WorldAtlas
WebOsmoconformation confers an advantage because it requires less energy than osmoregulation, and osmoregulation is disadvantageous as it requires more energy input. Osmoconformation may prove to be disadvantageous in environments exhibiting a wide range of salinities. In contrast, osmoregulation provides a possible advantage in such … Osmoconformers are marine organisms that maintain an internal environment which is isotonic to their external environment. This means that the osmotic pressure of the organism's cells is equal to the osmotic pressure of their surrounding environment. By minimizing the osmotic gradient, this … See more Invertebrates Most osmoconformers are marine invertebrates such as echinoderms (such as starfish), mussels, marine crabs, lobsters, jellyfish, ascidians (sea squirts - primitive chordates), and See more Ion gradients are crucial to many major biological functions on a cellular level. Consequently, the ionic composition of an organism's internal environment is highly regulated with respect to its external environment. Osmoconformers have adapted so that … See more WebVariations in salinity could cause osmotic stress to animals. Osmotic stress occurs when organisms are exposed to water and solute concentrations that are different from their normal internal concentrations (Freeman et al. 2014). Animals use two general strategies for coping with variations in salinity — osmoconformation and osmoregulation (Moyes & … farish 4f
