Answer:
1. adaption
Explanation:
Salmon have special adaptation behavior that allows them to live in both freshwater and saline water during their lives.
Salmons are born in freshwater where they spend few months and then move to saline water. For laying eggs, they again move to freshwater because eggs are unable to survive in saline water due to a process known as osmoregulation.
Moving from freshwater to ocean water, salmon adapt according to the environment for their survival.
Hence, the correct answer is "1. adaption"
This is an illustration of Sal-mon maintaining homeostasis.
Homeostasis
• Sal-mon possesses certain remarkable physiological and behavioral adaptations, which helps it to thrive in both salt water and fresh water habitats.
• In the given question, it shows that this is an adaptation of sal-mon to sustain homeostasis.
• One of these adaptations is negative feedback system in osmoregulation, to sustain homeostasis of the body.
• To disturb the dehydrating effect of salt water, sal-mon consumes many liters of water per day, however, when it moves to fresh water, the water loading issue prevails and because of excess salt in the body, it does not drink water at all.
Thus, the correct answer is option 5, that is, maintaining homeostasis.
