Ho sa tsotellehe hore na ho buuoa ka liketsahalo tsa khemistri ea bophelo tse potlakisoang ke li-enzyme, maano a ho ikatisa, kapa bokhethehi ba 'mele ba lintho tse phelang, litsamaiso tsa baeloji tseo bophelo bo itšetlehileng ho tsona ke litsamaiso tsa 'ohle kapa letho', tse sebetsang ka ho phethahetseng ho tloha letsatsing la pele 'me li lumella bophelo, kapa li bo thibela haeba ho na le liphoso litsamaisong.
Lifalke li tsoma linonyana tse nyenyane, li li tšoara li le moeeng ka lebelo le ka fihlang ho 300 km/hora. Sena se hloka pono e bohale le bokaholimo ba leihlo bo lulang bo hloekile bo bile bo tšela, leha lebelo le le holimo. Lifalke li na le letlalo la boraro la leihlo, le bitsoang nictitating membrane, le hoholang khafetsa le ka potlako holim'a khouna. |
Bokantle bo ka pele ba lera le tsamaisang la likhoho le na le mokotlana oa lisele tse kopanyang o bitsoang marginal plait. Mokotlana ona o na le sebopeho se sengata se kang moriri holim'a oona se tsejoang ka hore ke li-microvilli, tse sebetsang joalo ka borashe bo bonyenyane bo bokellang lera la meokho le litšila tse nyenyane 'me li li feela li li kenya ka har'a masoba a atolositsoeng, ao ebe li tsoela ka har'a tsamaiso ea meokho ea nko.
Difalkone di boetse di na le kgeleswa e kgethehileng, kgeleswa ya Harderian, e fumanehang botlaseng ba lera le tsamaeang ka leihlong. Kgeleswa ena e kgethehileng e tlotsa bokaholimo ba leihlo ka mokelikeli o kgomarelang haholo, o sa felloeng ke metsi habonolo, ho thibela moya ho etsa hore lera la dikeledi le bokaholimo ba leihlo le felloe ke metsi.
Dikarolo tse kgethehileng hakana tsa mahlo a ntsu, hammoho le pono e hlwahlwa le lebelo le tsotehang, di tlameha ho ba teng ka botlalo hore dinonyana tsena di phele. Dikarolo tse sa tswela pele ka botlalo di ne di ke ke tsa sebetsa boemong bo hlokehang hore dinonyana tsena di phele, mme sena se hanyetsa ka matla kgopolo ya hore di iphetotse butle-butle.
