Biology-Chemistry Of Life

Front 1

Water is a polar molecule. What does that mean?

Back 1

Water has an uneven charge, the oxygen end is -, and the hydrogen end is +

Front 2

Describe a water molecule. Include elements, bonds, and shared electrons.

Back 2

There is an oxygen molecule connected by covalent bonds.

Front 3

Cohesion: description, importance, example.

Back 3

Water sticks to itself (hydrogen bonds),

Surface tension,

Some lizards and insects can "walk on water"

Front 4

Adhesion: description, importance, example.

Back 4

Sticks to other molecules,

Capillary action, water molecules can tow each other, also water can contain minerals etc.

Water is sometimes mixed with flouride.

Front 5

Universal Solvent: description, importance, example.

Back 5

Acts as a solvent for many substances,

also why water can contain things like salt,

salt water

Front 6

Density Anomaly: description, importance, example.

Back 6

Less dense as a solid,

insulation of lakes,

ice in a glass of water will float.

Front 7

Why does water stick to itself?

Back 7

cohesion because of hydrogen bonds.

Front 8

What does water do when it freezes?

Back 8

expands

less dense

floats

Front 9

Why is water the universal solvent?

Back 9

It dissolves more things than anything else, because of its polarity

Front 10

Describe the pH scale.

Back 10

Ranges from 0-14, the lower the number the more acidic, the lower the more base. 7 is neutral.

Front 11

What is the difference between organic and inorganic molecules? Give examples of both.

Back 11

Organic molecules contain hydrocarbons.

Organic Molecules Include: vitamins, proteins, carbohydrates, etc.

Inorganic: water, minerals, etc.

Front 12

Describe the difference between a monomer and a polymer.

Back 12

Polymers are larger and are comprised of monomers.

Front 13

Front 16

Lipids

monomer

function(s)

Back 16

Monomer: Triglcerides (1 gylcerol, and 3 fatty acids)

Back 21

nitrogen

Front 22

How are amino acids connected

Back 22

peptide bonds

Front 23

How do most molecules connect?

Back 23
