1. Exposure with exogenously formed nitrosamines occurs by ingestion, inhalation, or by absorption through the skin.

2. Abscisic acid exogenously applied to actively growing plants rapidly induced turion formation even under noninductive environmental conditions.

3. Pupfishes frequently enter paradoxical Anaerobism in response to endogenously produced or exogenously supplied ethanol in a dose-dependent manner

4. Pupfishes frequently enter paradoxical Anaerobism in response to endogenously produced or exogenously supplied ethanol in a dose-dependent manner

5. Background: Pupfishes frequently enter paradoxical Anaerobism in response to endogenously produced or exogenously supplied ethanol in a dose-dependent manner

6. In exogenously feeding Alevins, the last enzyme involved in glucose production (g6pca and g6pcb) and lipolytic gene expression (cpt1a and cpt1b) decreased, while that of gk, involved in hepatic glucose use, was induced

7. An Angiogenesis inhibitor is a substance that inhibits the growth of new blood vessels (Angiogenesis).Some Angiogenesis inhibitors are endogenous and a normal part of the body's control and others are obtained exogenously through pharmaceutical drugs or diet.

8. 5. The rate of digestion of exogenously supplied proteins byZ. sociatus compares favourably with that of sea anemones and corals. Digestion is both extracellular and intracellular, the latter process taking place after particle phagocytosis in the “digestive-excretory” cells of the mesenteries proximal to the filament. 6. Z. sociatus can absorb dissolved amino acids and sugars from very low concentrations (10−6–10−7M), and may incorporate such metabolites particularly into reproductive tissue. 7.
