Ulwebhu
Ulwebhu lufana nenethi yemvelo, Izicabucabu ziyaziphotha ukuze zibambe izinambuzane,zisebenzisa imicu kasilika.Idizayini yolwembu isiza izicabucabu ukuba ziphile.[1]
Ulwembu luyizakhiwo ezikhethekile,eziphothelwe ngosilika ezihlukaniswa ngokuma nokusebenza, okuhlanganisa i-orb, ishidi,ifaneli,kanye nemiklamoephithene.Ama-orb webs angamaphethini ajwayelekile okuthandela, amatangle webs angcolile,anamathele,futhi avame ukutholakala emakhoneni.Usilika wesicabucabu wakhiwe ngamaprotheni amkhulu abizwa ngokuthi "ama-spidroins", Lawa maprotheni akhiwe ngamabhulokhi okwakha ama-amino acid alula, ikakhulukazi i-glycine ne-alanine.[2]
Imfihlo yamandla wolwembu avela ezifundeni ze-alainie.lezi zindawo zakha izakhiwo eziqinile,ezifana nekristalu lapho amabhondi e-hydrogen axhumanisa izintambo zamaprotheni ndawonye, okwenza nto ethi "phawundi" inamandla ukudlula izinhlobo ezahlukahlukene zey'nsimbi, Ikhona ukunwebeka ngaphandle kokuphuka.[3]
Kunezinhlobo eziningana ezihlukene zolwembu, ngayinye enezici nezinjongo ezehlukile.Kukhona i I-Orb webs, lwembhu yakudala eyindilinga ecatshangwa abantu abaningi. ukubukeka kwaso kume okwesondo ngezipikili ezikhazimulayo neziyingi ezigxilile, inhloso yayo idizayinelwe ukuthwebula izinambuzane ezindizayo.Kukhona I- Tangle webs ulwembhu olungajwayelekile, olungcolile olutholakala emakhoneni. Ukubukeka akuhlelekile elinezi nhlangothi ezintathu, injongo ukuhambela izinzmbuzane ezinwabuzelayo, futhi isebenza njengendawo yokubalekela isicabucabu.[4]
