Question 1

How does the structure of water contribute to its unique properties

Answer 1

Because it’s polar it can form multiple hydrogen bonds

Question 2

How does water’s polarity influence its properties as a solvent

Answer 2

Gives it the ability to dissolve ionic compounds and other polar molecules

Question 3

Why is it important for cells to buffer solutions against rapid changes in pH

Answer 3

So homeostasis can be maintained
