Start Quiz
1.

Water is a polar molecule because

it is ionic
oxygen is more electronegative than hydrogen, giving unequal sharing of electrons
hydrogen is more electronegative
it is linear
2.

Cohesion is

attraction of water to other surfaces
the dissolving of ions
the attraction between water molecules
evaporation
3.

Water’s high specific heat helps organisms by

speeding reactions
lowering pH
reducing cohesion
moderating temperature changes
4.

Ice floats because

it is heavier
it has no hydrogen bonds
it is non-polar
hydrogen bonds hold molecules in a less dense lattice
5.

Which elements are found in all carbohydrates?

C, H, O and N
C, H, N and P
C, H and O
C and N only
6.

Nitrogen is needed by organisms to build

carbohydrates only
lipids only
water
proteins and nucleic acids
7.

Evaporative cooling works because

water is cold
hydrogen bonds form
ice forms
the molecules with the most kinetic energy leave, lowering the average
8.

Surface tension is a result of

adhesion
ionic bonds
low density
cohesion among water molecules at the surface
9.

Capillary action in plants depends on

ionic bonding
cohesion, adhesion and transpiration
active transport of water
gravity
10.

Carbon is central to biological molecules because it

is ionic
forms only one bond
is rare
forms four covalent bonds, giving diverse stable structures
