Kwi-astronomy, imetal yiyo nayiphi na i-element yekhemikhali ongaphandle kwe- hydrogen okanye i-helium. Unobangela woko kukuba ezi elements zimbini (nganye amaxesha kuba yi-lithium) zizo kuphela ezenza umququmblelo wee-nkwenkwezi. Esibhakabhakeni, i-telescope ingazibona iimpawu zee-metals ize ke emva i-astronomer yazi okokuba kukho ii-nkwenkwezi.

UAbram (onguAbram) yindoda ekubhalwe ngayo kwincwadi yeGenesis nakwiQu'ran. Apho, ke kuthiwa unguyi wamaJuda. Kungenxa yokokuba usisinyanya sawo. UAbram uyinxalenye yeenkolo yamaJuda, yamaKristu kunye namasilamsi. UAbram waziwa njengoyise wezi nkolo zintathu, nezibizwa ngokuba ziinkolo zikaAbram.

I-Sulfur ingafumaneka emhlabeni kufuphi nee-volcanoes. Ii-minerals ezininzi zinee-sulfur ions. Amalahle ane-sulfur ions ezivela xa esitsha. I-Hydrogen sulfide ne-sulfur dioxide zezinye ii-sulfur compounds ezithi zikhutshwe xa esitsha amalahle. Zenziwa ukuba zisebenze ukuze kwenzeke i-sulphur. Xa isemhlabeni i-sulphur, iyanyibilika, ize ityhalwe ngamandla inyuke ngemibhobho ngenxa yomoya oza ngoxinzelelo othi uminxane kule mibhobho.

Kukho into engaqhelekanga eCanada; ikomkhulu lezizwe ezimanyeneyo, iOttawa, akuyodolophu inkulu kwiphondo layo. I-Ontario, ekuyiToronto. Kodwa kwenzekile okokuba iToronto ibe likomkhulu lephondo iOntario. ngale ndlela ke, iToronto ilikomkhulu iphinde ingabilokomkhulu, kuxhomekeke kwindlela oyibona ngayo, njengedolophu yesizwe okanye njengenxalenye yeendawo zesizwe.

Ukwahlulwa-hlulwa kwe-cell kuxa i-cell enye nengunozala wezinye ii-cell yahluke kubini nangaphezulu sithi ezo zii-daughter cells. Ukwahlulwa-hlulwa kwe-Cell kuyinxalenye yokwenzeka kwe-cell cycle. Zimbini iintlobo-ntlobo zokwahlulwa-hlulwa kwe-cell Kwi-eukaryotes: yi-vegetative division, apho intshontsho le-cell ngalinye lifana nqwa nonina i-cell engunozala ke ukutsho. Oku kwahlulahlulwa kwe-cell kwaziwa ngokuba yi-(mitosis), kunye ne-reductive cell division, apho inani lee-chromosomes ezifumaneka kwintshontsho le-cell (daughter cells) liphungulwa ngenani eliyihafu kwelo lazo liphelele, ukuze kwenzeke ii-haploid gametes leyo ke kuthiwa yi-(meiosis). Xa kusenzeka i-Meiosis kuphuma ii-four haploid daughter cells ezine ngokuthi zenze umjikelo omnye we-DNA replication ize ilandelwe kukwahlula-hlulwa okwenzeka kabini:
