Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mhuka dzose dziri pasi pano dzinoda mabhakitiriya kuti dzirarame nokuti mabhakitiriya chete nemamwe makemikari ndiwo ane majini nemaenzyme anodiwa pakugadzira vhitamini B12, inozivikanwawo secobalamin, uye kuigovera muketani yezvokudya. Vitamini B12 ivhitamini inonyungudika mumvura inobatanidzwa mumetabolism yesero rimwe nerimwe romuviri womunhu. Iyo cofactor muDNA synthesis, uye mune ese maviri mafuta acid uye amino acid metabolism, Inonyanya kukosha mukushanda kwakaringana kweiyo nervous system kuburikidza nebasa rayo mukugadzirwa kwe myelin.Pane kazhinji mamirioni makumi mana emakemikari maseru mugiramu yeguruva uye miriyoni yemakemikari maseru mune millilitre yemvura yakachena. Kune mabhakitiriya anenge 5x1030 ari pasi pano, anoumba zvinhu zvipenyu zvakawanda kupfuura zvinomera nemhuka. Mabhakitiriya anokosha mumatanho mazhinji omutambo wezvinovaka muviri kupfurikidza nokudzokorora zvinovaka muviri zvakadai sokugadziriswa kwe nitrogen kubva mumhepo. Kutenderera kwezvinhu zvinovaka muviri kunosanganisira kuora kwemitumbi yakafa; utachiona ndihwo hunoita kuti muviri uore. Munzvimbo dzinogara zvipenyu dzakapoteredza nzvimbo dzinobuda mvura inopisa uye nzvimbo dzinotonhora, utachiona hunonzi extremophile hunopa zvinhu zvinovaka muviri zvinodiwa kuti upenyu hurambe huchienderera mberi nokuchinja zvinhu zvakanyungudutswa, zvakadai sehydrogen sulphide nemethane, kuti zvive simba. Mashoko akataurwa nevatsvakurudzi muna October 2012 uye akabudiswa muna March 2013 akaratidza kuti utachiona hunorarama muMariana Trench, iyo yakadzika makiromita 11 uye ndiyo yakadzika zvikuru mumakungwa yatinoziva. Vamwe vatsvakurudzi vakataura nezvezvidzidzo zvakafanana zvokuti utachiona hunorarama mumatombo ari pasi pemamita 580 pasi pegungwa makiromita 2,6 mumakungwa ari kumhenderekedzo yokuchamhembe kwakadziva kumadokero kweUnited States. Maererano nomumwe wevanzveri, "Unogona kuwana utachiona kwose kwose - hunochinjika zvikuru kumamiriro ezvinhu, uye hunorarama kwose kwahunenge huri". Kune anenge matiririyoni 39 emasero eutachiona muhutachiona hwevanhu se...  Mubvunzo: Mumakumi emakore api pakachinja marongerwo emabhakitiriya?
