Question

Water has properties that make it _______ to life on earth. Water is _______ in that water molecules will stick to other water molecules. It is a _______ because other substances will dissolve in it. Water moderates temperatures mainly because it can _______ a lot of energy before rising in temperature. Lastly, water is _______ when frozen. This helps protect aquatic life by only freezing on the top layers.

1) vital, absorb, solvent, cohesive, more dense, less dense, unimportant
2) important, dissolve, cohesive, absorb, less dense, more dense, vital
3) essential, stick, solvent, cohesive, less dense, more dense, unimportant
4) crucial, dissolve, solvent, cohesive, more dense, less dense, vital

Answer 1

Water is crucial to life on earth because of its cohesive, solvent, temperature-moderating, and less dense when frozen properties.

Step-by-step explanation:

Water is crucial to life on earth because it has several properties that are vital for living organisms. Firstly, water is cohesive, meaning water molecules stick to other water molecules. This cohesion allows for the transport of water through plants and the movement of blood in animals.

Additionally, water is a solvent, which means that other substances can dissolve in it. This property is important for chemical reactions and metabolism within cells. Water also moderates temperatures because it has a high heat capacity, meaning it can absorb a lot of energy before rising in temperature. This helps to stabilize the temperature of the environment and prevent drastic fluctuations. Lastly, water is less dense when frozen, which allows ice to float on top of water. This is important for protecting aquatic life by providing insulation and preventing the freezing of entire bodies of water.
