I-Sarracenia yizitshalo ezidlayo ezidinga ukulala ukuze ziqhubeke zikhula entwasahlobo.
Njengamabhere, izitshalo nazo zidinga ukulala ubusika bonke. Yiqiniso, azikwazi ukufakwa emihumeni noma emakamelweni anoma yiluphi uhlobo ngoba, njengoba sazi, abanayo imilenze noma imilenze, kepha abayidingi, ngani?
Ngoba nabo, njengathi, banesigqi se-circadian, okungukuthi, baphendula amahora okukhanya kwelanga, okungukuthi, ekuseni basebenzisa amandla kuze kufike emini, ntambama basebenzise amandla abo asele, nasebusuku bavame ukuthuthukisa ushukela kumaseli abo ukuze bakwazi ukuqhubeka bekhula ngosuku olulandelayo. Kepha, Kunjani ukulala ubusika bonke ezitshalweni?
Izitshalo zidinga ukukhanya ukuze zikhule, futhi uma isikhathi sasemini sikhona, isikhathi esengeziwe abazoba naso ngaso. Kepha futhi kubalulekile ukuthi izinga lokushisa limnandi kubo, ngaphandle kwalokho ngeke bakwazi ukukhula. Leli zinga lokushisa lizohluka ngokuya ngohlobo nezinhlobonhlobo zalo, kepha ngokujwayelekile singasho ukuthi badinga isilinganiso esingu-14ºC okungenani ukuze amaseli abo enze imisebenzi yawo kahle.
Nokho, Njengoba ukuwa nobusika kusondela, izinsuku ziyancipha futhi izinga lokushisa lehla. Ngakho-ke ngalezi zinsuku izitshalo zizoqhubeka zisebenzisa ukukhanya kwelanga ukugcina nje ukudla ukuthi bazoyisebenzisa lapho isimo sezulu esihle sibuya, hhayi okuningi okuzokhula. Eqinisweni, izinga lokukhula liyancipha njengoba amakhaza enyuka, emiswa ngokuphelele ezifundeni lapho kwenzeka khona isithwathwa nokuwa kweqhwa.
Kwenzekani uma bengalali ubusuku bonke? Into efanayo engenzeka kithina uma singalali: impilo ibizobuthaka, ngakho-ke bangaba sengozini enkulu yokuhlaselwa isikhunta, izimuncagazi nanoma yini enye into ephilayo efuna ukubathinta.
