Water
Water is a molecule and the picture shows the structure and the polarity of the molecule.
Adhesion is when two different molecules attract.
Cohesion is when two of the same molecules attract.
Heat storage collects polar heat and keeps it to use it when the temperatures are cool.
pH is the level of acid.
polarity is having a negative and a positive charge.

Macromolecules
Macromolecules has a lot of atoms. The 4 groups are Proteins, Nucleic Acid, Carbohydrates and Lipids. Macromolecules are needed in the human body to live. They carry dna, rna and. They also store and provide the bodies energy. They also make fat for the body to burn.
Carbohydrates
Potato's are high in starch. Starch is made of carbohydrates. Carbohydrates produce and store energy.
Another example is simple sugars. Simple sugars are needed in to human body.
Carbohydrates are in a lot of foods we eat daily like bread, cookies, pasta, and even peanutbutter. People eat carbs so that they can burn energy. Carbohydrates are long term energy sources.
Lipids
Oil is an example of a lipid. A lipid's function is to produce fat.
Fatty Acid
Lipids structure is made up of fatty acid. Fatty acid is made of chained methylene.
Examples of Lipids
Other examples of lipids ate trans fats unsaturated fats and saturated fats.
Proteins
Protein's function is to provide energy, store energy, dissolve other nutrients, and control chemical reactions. Proteins are made up of a lot of animo acids. Examples of proteins are eggs, poultry, meat, cheese and nuts.
Example of Proteins!!!
Protein structure
Eggs
are an example of proteins
Cheese
also consist protein
Nucleic acids
An example of a nucleic acid is DNA, also known as deoxy ribo nucleic acid. The function of this nucleic acid is to carry heredity traits.
Another example is ATP also known as adenosinetriphosphate which is an energy bank.
The last example is RNA also kno as ribonucleic acid which carries instructions for making protiens.
