|---|---|
| What is a chemical level? | there are more than a 100 different chemical building blocks of nature called the atoms-tiny spheres of matter so small they are invisible, every material thing within the universe includes the human body composed of atoms. |
| What is the internal environment? | the body cells survived in a healthy condition only when the temperature, pressure, and chemical composition of their fluid environment remained relatively constant |
| What is the elements and compounds? | to be "pure" in the sense that it cannot be broken down or decomposed into a two or more different substances, the carbon and oxygen are a good examples, of elements it exist alone in their pure form |
| Organics and Inorganics Compounds | in the living organism there are two kinds of compounds: organiz and inorganic, that contain carbon-carbon, covalent bonds, or carbon hydrogen, covalent bonds, or both kinds of bonds. |
| Carbohydrates | there are compounds that contain the elements carbon, hydrogen, and oxygen, that usually within a ratio of 1:2:1, it includes the substances called sugar and starches |
| Proteins | proteins are four elements carbon oxygen, hydrogen, and nitrogen, it also contains small amounts of sulfur, iron, magnesium, zinc, and other trace metals |
| Cell structures | ideas about cell structure have changed considerable over the years, biologist know that cells are far more complex than this, in each cell there it is surrounded by a plasma membrane that separates the cell from it surrounding environment. |
| Specificity | the structural characteristics of transporters such as size, shape, and charge that determine what they transport a property. |
| What is the importance of protein synthesis? | is an important process because it influences all cell structures and functions, the elements themselves or are enzymes or other functional proteins that direct the synthesis of other proteins |
| ECM | it is not "just" water, or even water with a gel that in many tissues is a bit like jelly |
