Answer:
irreversible chemical change
Explanation:
A chemical change always results in a new substance and as it is not possible to reverse it, it is an irreversible chemical change.
I hope you understood :)
 
        
             
        
        
        
(1) they keep toxic substances out of the cell; 
(2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment;
(3) they separate vital but incompatible metabolic processes conducted within organelles.

Answer: YES, SUPPORTED 
Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.
These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.
In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).
