WATER
Water has many characteristics that apply to it. Some examples of these characteristics are adhesion, cohesion, polarity, heat storage and pH.
Adhesion
Adhesion is when water molecules are attracted to other substances. For example, when you see a dewdrop on a leaf after it rained, this is an example of adhesion. The water molecules, which in this case is the dewdrops, is clinging to the other substance, which is the leaf.
Cohesion
Cohesion is when water molecules attract to other water molecules. For example, did you ever wonder how a water drop keeps its shape? This is because of cohesion. Because of cohesion, the water molecules attract to other water molecules, which allows all the molecules to form into a water drop.
Polarity
Polarity is when a molecule has both a positively and negatively charged end. Water is considered a polar molecule because of the difference between hydrogen and oxygen. This is also called electronegativity. Electronegativity is the measure of attraction of an atom for the electrons in a chemical bond.
Heat Storage
Heat storage is when a device or medium absorbs collected solar heat and stores it for periods of inclement or cold weather. This can also be applied to water. When water is heated, it takes a long time to cool down due to the heat that it contains
pH Levels
pH is the measure of how acidic or basic a substance is. Water isn't found to be acidic or basic, just in the middle. Pure water is found to have a pH very close to 7, which makes it not very acidic or basic.

Adhesion & Cohesion
This shows the difference between adhesion and cohesion.
Polarity
This shows what a polarity is.It also shows how it takes 2 hydrogens and 1 oxygen to make a water molecule.
Ph scale
This shows the ph scale of common substances.
Marcomolecules
Marcomolecules
What is a macromolecule? A macromolecule is a molecule containing a very large number of atoms. Some examples of macromolcules are the four types of carbs are monosaccarides, disaccarides, oligosaccarides, and polysaccarides.

Structure and Fuctions
This shows the how a macromolecule works and how structured it is.
The Spectroscopy
This shows the macromolecules process and what happens.
Carbohydrates
Carbohydrates
A carbohydrate is an organic compound that is made up of hydrogen, carbon and oxygen. Carbs are a key source of energy for the body and is found in most foods. Another job that carbs preform for the body is a defense against invading viruses and bacteria.Some examples of carbohydrate are proteins, nucleic acids and carbohydrates.

Proteins
Proteins
Proteins are complex molecules that help your body perform a variety of biological functions. There are five different types of proteins. Those five types are: structural, storage, hormonal, enzyme and immunoglobin proteins.

Lipids
A large and diverse group of naturally occurring organic compounds that are related by their solubility in non-polar organic solvents (e.g. ether, chloroform, acetone & benzene) and general insolubility in water. All Lipids are hydrophobic: that’s the one property they have in common. This group of molecules includes fats and oils, waxes, phospholipids, steroids (like cholesterol), and some other related compounds.

This shows the chain of lipids and what's in them. Also how they're connected.
Oils & Fats
This shows the chain of oil and fat lipids. and what its made up of.
Classification
This shows the classifications in Lipids and the chain.
Nucleic Acids
They allow organisms to transfer genetic information from one generation to the next. There are two types of nucleic acids: deoxyribonucleic acid, better known as DNA and ribonucleic acid, better known as RNA. Nucleic acids are composed of nucleotide monomers. Nucleotides have three parts:
- A Nitrogenous Base
- A Five-Carbon Sugar
- A Phosphate Group
Components
