    GO ID   Ontology GO Term Definition
    1666   Response to Hypoxia  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Stimulus Indicating Lowered Oxygen Tension. Hypoxia Defined As a Decline in O2 Levels Below Normoxic Levels of 20.8 20.95% Results in Metabolic Adaptation At Both the Cellular and Organismal Level. 
    6810   Transport  The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore. 
    6979   Response to Oxidative Stress  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of Oxidative Stress a State Often Resulting From Exposure to High Levels of Reactive Oxygen Species E.g. Superoxide Anions Hydrogen Peroxide (h2o2) and Hydroxyl Radicals. 
    10764   Negative Regulation of Fibroblast Migration  Any Process That Decreases the Rate Frequency or Extent of Fibroblast Cell Migration. Fibroblast Cell Migration Is Accomplished by Extension and Retraction of a Pseudopodium.
