Question 1

What does it mean by water molecules being polar?

Accepted Answer

This means that water has partial postive and negative charges

Question 2

Where do hydrogen bonds form in water molecules?

Accepted Answer

Between the postive H and Negative O

Question 3

What are the 5 properties of water?

Accepted Answer

-It is a metabolite -It is a solvent -It has a high specific heat capacity -It has a high latent heat of vaporisation -It has cohesive forces between water and molecules

Question 4

What does being a metabolite mean?

Accepted Answer

A substance necessary for or taking part in a particular metabolic process

Question 5

Why is water a metabolite?

Accepted Answer

It is used in hydrolysis reactions and is a product of condensation reaction

Question 6

Why is it important that water is a solvent?

Accepted Answer

Substances can dissolve in water allowing metabolic reactions to occur and substances to be transported

Question 7

Why is it important that water has a High specifc heat capacity?

Accepted Answer

So it buffers (resists) changes in temperature

Question 8

Why is it important that water has a High latent heat of vaporisation?

Accepted Answer

Evaporation of water exerts a cooling effect on organims

Question 9

What 2 reasons are there for water having cohesive forces between water molecules?

Accepted Answer

-Suports water colums in the xylem -Creates surface tension so supports organims
