B. Water resists changes in temperature, absorbing and releasing heat slowly.
C. Water's boiling and freezing points are important for ecosystems because they prevent drastic changes that could kill organisms
D. Water molecules stick together tightly due to hydrogen bonds, which are stronger than most other liquids

Answer 1

All the options listed describe unique properties of water:

A. **Water's ability to dissolve many substances** - Water is often referred to as the "universal solvent" because it can dissolve many ionic and polar substances.

B. **Water resists changes in temperature, absorbing and releasing heat slowly** - This property, known as high specific heat, allows water to moderate temperatures in the environment.

C. **Water's boiling and freezing points are important for ecosystems because they prevent drastic changes that could kill organisms** - The relatively high boiling point and low freezing point of water allow for a stable environment in which organisms can thrive.

D. **Water molecules stick together tightly due to hydrogen bonds, which are stronger than most other liquids** - This property, known as cohesion, allows water to have high surface tension and contributes to its movement in plants and other organisms.

So, you should check all options A, B, C, and D.
