Amandla obuthi

Ukuluma

Ubuthi buphuma ngamazinyo aso obuthi noma ngamazinyo uma siluma.

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKungaba buhlungu ngempela, kodwa cishe akukaze kube kubi kakhulu.

Uma siluma

Gcina umuntu engashukumi futhi ezolile, gcina isitho esilunyiwe sisezingeni lenhliziyo, khipha izindandatho nezinto eziqinile, bese umusa esibhedlela ngokushesha.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma sikuluma: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

kuhle ukwazi

Amaqiniso

It has three recognised subspecies, and genetic studies show strong differences between them that match geographic barriers.1

A genetic study using nuclear markers places it at the base of its species complex, meaning it is the earliest branch among its close relatives.1
