Fish with antifreeze blood
WebMar 7, 2011 · This hands-on activity serves as an introduction to the film The Birth and Death of Genes. Students investigate the importance of antifreeze proteins for icefish survival through one of two short labs. The activity includes two short labs that allow students to explore a key adaptation introduced in the film: antifreeze proteins in the blood. WebFour main observations have been used in AFGP studies: (a) The ice crystal habit (size) affects the activity, (b) AFGP is on the surface of ice crystals, as shown by surface second harmonic generation (SSHG), (c) the presence of AFGP lowers the surface energy at the ice-solution interface, and (d) kinetic calculations of the inhibition of ice ...
