Water

Question 1

Waters useful properties (5)

Answer 1

Important metabolite
High latent heat of vaporization 
High specific heat capacity/temperature buffer
Good solvent
Cohesive

Question 2

Why is waters high specific heat capacity useful for living organisms

Answer 2

Helps organisms maintain a constant internal body temperature
Good habitat as temp is more stable
No rapid temperature changes

Question 3

Waters structure

Answer 3

H2O
Oxygen has a slight negative charge because of unshared electrons
Hydrogen has a slight positive charge because the electrons are shared and pulled toward ma the oxygen atom so other side is positive
This causes the opposing charges to attract this is called hydrogen bonding
