1. 1.__________-process by which waste products of metabolism and other non-useful materials are eliminated from an organism
2.__________ -The maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations.
3.__________ -Epithelial tissue whose functions include secretion, selective absorption
4.__________ -Nitrogenous waste found in aquatic organisms that ispoisonous and highly toxic in terrestrial organisms.
5.__________ -Nitrogenous waste that is water soluble and relatively has a low toxicity level if used by terrestrial organisms.
6.__________ -Nitrogenous waste that is water insoluble and usually found in insects and birds.
7.__________ -the measure of solute concentration
8.__________ -marine invertebrate that maintains its internal salinity such that it is always equal to the surrounding aquatic environment
9.__________ -active regulation of the osmotic pressure of an organism's fluids to maintain the homeostasisstenohaline
10._________ -Able to tolerate a wide range of salinity
11._________ -Able to tolerate only a narrow range of salinity
12._________ -Substance that protects sharks from the nitrogenous wastes that they release
13._________ -an ametabolic state of life entered by an organism in response to adverse environmental conditions such as desiccation
14._________ -an ametabolic state in organism
15._________ - a sugar molecule that helps organisms such as the water bear (tardigrade) to reach an ametabolic state without comprising their cells.
