8.What happens to a freshwater fish in saltwater?
It absorbs water
It loses water
It becomes buoyant
It thrives
إجابة صحيحة
السؤال - 9
9.Which of the following correctly describes osmotic pressure?
The force exerted by solutes in a solution

إجابة صحيحة
السؤال - 10
10.What is a key difference between cellular respiration and gas exchange?
Cellular respiration occurs in all organisms
Gas exchange occurs at the cellular level
Cellular respiration produces energy, while gas exchange involves the transfer of oxygen and carbon dioxide
Gas exchange is only in aquatic organisms
