| Question | Answer |
|---|---|
| how do organisms get the molecule they need to function? | The cells and tissues of virtually all organisms are made up of the same basic molecules. Many of these are substances with which we are familiar: our carbohydrates, lipids, proteins and the nnucleic acids. |
| Why is Bio chemistry important to Biology? | All Life depends on chemical reaction: Atoms combining and recombining, compounds being formed and broken own and the formation of new compounds |
| Proton | the number of protons determines the atomic number, it never varies: the location of the proton is in the nucleus the charge is positive(+), size= to neutron |
| Neutron | Added with the proton equals the atomic mass it can vary in number. The location is in the nucleus there is no charge and it equals to proton |
| Electron | equals in number to the protons as a general rule charge are equal and opposite (identified as +-), orbiting the nycleus, negative charge(-), responsible for chemical activity of atoms, flow of energy in living things(nerve impulses) |

| Structure of DNA and RNA | DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.RNA is a single strand right-handed helix. It's backbone structure is made from ribose sugars, phosphate, and the four bases adenine, guanine, cytosine and uracil. |
| Chemical bond | a chemical bind is a union between atoms that is formed when atoms give and take or share electrons |
