I-tench: le nhlanzi isibona kanjani isiyengo sakho
I-tench: yimuphi umbala wesiyengo le nhlanzi ekwazi ngempela ukuwubona, ekujuleni kwakho nasemanzini akho. Izinhlobo zamakhoni ezingu-3, isiqongo ku-620 nm. Umehluko ohleliwe wemibala engu-54.

Kukaliwe emndenini ofanayo
Alukho ukukala kwe-spectrum okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe ezingeni lomndeni ku-amanye ama-cyprinid. Lokhu kuwukucabangela okungacijile kunokuthatha esihlotsheni sohlobo olulodwa; impendulo ebanzi ethi “yimuphi umkhawulo we-spectrum” iyathembeka, kanti ukuhleleka okucijile phakathi kwemibala eseduze akuthembeki. I-retina yalo isebenzisa i-chromophore ye-A2 (i-porphyropsin), edlulisela ukuzwela kwamagagasi amade kudlulele kobomvu kunalokho i-retina ye-A1 ebiyokunika khona. Izinhlanzi eziningi zamanzi amtoti ziyaguqula isilinganiso se-A1/A2 ngenkathi yonyaka nangokushisa, ngakho ukuzwela kwangempela kuyantweza unyaka wonke.
Ukuzwela kwe-spectrum
| Iziqongo zamakhoni | λmax | I-chromophore |
|---|---|---|
| Obufushane | 450 nm | A2 |
| Obuphakathi | 535 nm | A2 |
| Obude | 620 nm | A2 |
| Irodi | 530 nm | A2 |
Amarodi yiwo asebenzayo entathakusa, kuhwalala nasebusuku — okuyisikhathi abantu abaningi abadoba ngaso.

Emithathu ephume phambili, iseshwa ku-Amazon yakho. Ukuhleleka okungenhla kubalwa ngamanzi nangenhlanzi, ngaphambi kokuba lezi zixhumanisi zibe khona.

Imibuzo abantu abayibuzayo ngempela
I-tench: ingabe le nhlanzi iyayibona imibala?
Yebo. Inezinhlobo zamakhoni ezingu-3, eziqonga ku-450 nm, 535 nm, 620 nm. Lokho kuyinika izinhlangothi zombala ezingu-2, uma umuntu enezimbili.
