• Sleep - biology.

  V FUNCTIONS OF SLEEP Although no one knows for sure why we sleep, there are a number of theories. Sleep may have evolved to protect animals from their predators by reducing theiractivity during the times when they are most vulnerable. Research has shown that REM and NREM sleep may serve specific biological functions. Sleep deprivation studies reveal that humans and other animals respond to sleeploss in the same way. When study subjects are deprived of REM sleep, they tend to spend longer period...

Alors que, jusqu’ici, on tuait les cétacés au moyen de lances et deharpons actionnés à la main, il fabrique un canon-harpon qui tire un obus en acier entraînant le harpon et le câble. Une fois dans le corps de l’animal, le projectile explose,entraînant la mort du cétacé beaucoup plus rapidement qu’un harpon traditionnel. Svend Foyn monte son arme à bord de baleinier...

• poissons (zoologie).

  La plupart des poissons osseux possèdent un organe servant au contrôle de la flottaison, la vessie natatoire.

La fonction principale de cet organe est d'adapter le poisson aux variations de la pression de l'eau à différentesprofondeurs. L'appareil circulatoire de la plupart des poissons est simple et consiste en un cœur à deux cavités, qui envoie le sang à travers les branchies, pui...
