Through expanding, some galaxies are on a collision course with us.
The fish use reacting behavioural mechanism in order to protect itself from the danger.
The fish uses reacting behavioural mechanism when the fish sense any type of danger surrounds it. This behaviour is a type of defense mechanisms which is used to defend and protect itself.
The fish apply electric shock in order to protect itself from the attackers and give harm to the other organisms which comes in contact with it so we can conclude that the fish use reacting behavioural mechanism in order to protect itself from the danger.

One way is to see if it responds to stimulants or if it reproduces
Yes, in my opinion 20 ml of soda has a greater mass than 20 ml of water due to higher weight of soda particles as compared to water.
It is because solid substance is more denser than liquid. In 20 ml of soda, there are solid particles in it which make it heavier and denser than liquid water. In order to design this, we have to take two solutions, one having soda whereas the other has water in liquid form with equal concentrations. Then we have o find the density of both solution, that solution which has more density is considered as heavier than other solution. The density of soda is 2.54 g/cm³ whereas the density of water is 1 g/cm³ so it is clear that soda is denser than water.
