Water
- Adhesion - Adhesion is an attraction between different substances(not alike)
- Cohesion - Cohesion is an attraction between substances of the same kind(are alike)
- Polarity - The polarity of water enables it to allow other substances to dissolve in water (polar/non-polar molecules)
- Polar Molecules - Polar molecules are molecules that dissolve well in water.
- Non-polar Molecules - Non-polar molecules are molecules that do not dissolve well in water
- Storage of heat (Heat Storage) - This is the ability to control temperatures enables cells to maintain a constant internal temperature when the external temperature changes drastically.
- Ph - The Ph scale measures the concentration of hydrogen ions in solutions on a scale between 0-14. 0-6 being more acidic containing things like lemons and vinegar. 7 being evened out which is milk. And 8-14 being the more basic which contains items like Hand Soap and Household Ammonia
Lemons The lemon has the high acidic base and is at 2 on the Ph scale and is really sour | The Scale This isn't the scale you think it is, it's the scale that measures the hydrogen ions in a concentrated solution. | Heat Storage!A pot of boiling water takes longer to return to room temperature simply because water retains and stores heat longer than any other substances. |
The Scale
This isn't the scale you think it is, it's the scale that measures the hydrogen ions in a concentrated solution.
General Info, Macromolecules
Macromolecules are large molecules that is made with carbon(C), other atoms used are Hydrogen, Nitrogen,Oxygen,Phosphorus, Sulfur etc. Note: in order to be organic the molecule needs to be made of carbon.
There are 4 types of macromolecules
- Carbohydrates
- Proteins
- Lipids( other known as fats)
- Nucleic Acids
Carbohydrates
- Carbohydrates are organic compounds made of Hydrogen(H), Carbon(C), and Oxygen(O). These are the key source of energy for the body and is found in most foods.
- There are 4 types of carbohydrates. there is Monosaccharides, Disaccharides, Oligosaccharides, and Polysaccharides
Proteins
- Proteins are chains of amino acids folded into blobs with special shapes. Each shape of a protein has its own lock and key and function. A protein cannot work without its shape and if proteins didn't have the shapes it does we would die.
Nucleic Acids
- There are 3 types of nucleic acids and those are, DNA RNA and ATP.
Lipids
- Lipids is another name for fats. The purpose for lipids or fats is to make up cell membranes, and to give the body long term energy.
