I-Mutagenes echaphazela ubomi bomntu. Mutagen ...

Mhlawumbi wonke umntu uyaziqhelanisa negama elinjalo njengesigidimi. Ingumntu onokuthi abe nohlobo oluhlukileyo kwaye ahluke ngobunzima besiphumo. Zingonakalisa uluntu kunye nabantu. Kodwa iipropati zabo zisoloko zisetyenziselwa izinto ezifanelekileyo kwiindawo ezahlukeneyo zobomi.

Yiyiphi intetho

Wonke umntu unengcamango yakhe yintoni uhlobo lwezinto. Kodwa ngokwenene i-mutagen yinto ebangela ukuguqulwa okuqhubekayo kwisakhiwo somzimba. Ezi zinguqu zihlala zizuzwe njengezizukulwana ezilandelayo.

I-Mutagens inezinye i-acids, zonke iintlobo zeemveliso, iziyobisi kunye neemeko ezithile zemitha. Basenokuba nesifo sengculaza. I-Mutagen yinkcazo yendalo yonke into eyenza ukuguquka kunoma yiphi na inyama, kuqala ngeibhakteria kunye nokuphela kwezityalo kunye nabantu. Ubukhulu beenguqu buxhomekeke kumyinge.

Iintlobo zeentengiselwano

Iintlobo ezintathu ze-mutagens ziyaziwa namhlanje: ezemvelo, iikhemikhali kunye ne-biological. Udidi lokuqala luquka yonke imirhumo ye-ionizing. Ezi zi-X-ray kunye ne-gamma ray, i-neutron, i-proton, i-ultraviolet. Kuyathakazelisa ukuba, kwinqanaba elithile, ukushisa okuphakamileyo okanye okuphantsi kushukumisa utshintsho kwisakhiwo somzimba, nangona oku kuguqulwa kuncinci.

Olunye udidi luyimizimba yamachiza. Ezi ziquka i-DNA yangaphandle, i-alkylating compounds (dimethylsulfate, lwesardard, njl.), I- nitrous acid, i- pesticides, i-acridine idayi, i-formaldehyde, i-alkaloid kunye ne-peroxide ephilayo. Oku kufaka ezinye iziyobisi, kwakunye nezinto eziye zaphandwa ngayo. Izigulane ze-Biological zingaba yiintsholongwane, ezinye izityalo kunye nezinto eziguqulwa ngokwemizimba.

I-Mutagens nabantu: izinto ezinobungozi

Izazinzulu zisoloko zisebenzisa ama-mutagens ukuze kuzuze uluntu, umzekelo, zisetyenziswe ngabafuyi. Kodwa igalelo labo elibi limelele ngakumbi. Ukufumana iimveliso ezininzi, iziyobisi, iimveliso zokucoca kunye nezixhobo zasendlini, umntu uzichazela kwimiphumo ye-mutagens, ebangela umonakalo emzimbeni. Ngokuqhelekileyo oku kwenzekayo kungabonakaliyo kumntu ngokwakhe kwaye kubonakaliswe kwisizukulwana esilandelayo kuphela. Ngelishwa, sele sele udibanisa nezinto ezinjalo zibangele izifo ezitsha, iziganeko ezingapheliyo kunye nezicubu. Abavelisi beempahla ezininzi eziyimfuneko kumntu wanamhlanje badla ngokuvelisa ekubunjweni kwabo oku okanye ukuthutha. Ingaba iintlobo zeentlanzi, ukutya, iikhemikhali zendlu, ukukhupha umsi, inkunkuma yoshishino kunye nokunye okuninzi. Zonke ezi zinto zinyuka emoyeni, zihlala emhlabeni kwaye zithatyathwa yizityalo ezingena ekudleni. Ukongezelela, izithintelo zendalo zithintela izilwanyana kunye nezinambuzane, ziguqula imikhwa yazo, zibenza zikhuthele kwaye zisengozini kwizifo. Kubalulekile ukuba kuqaphele ukuba akukho tshintsho oluya kunceda umzimba.

Ukutya kunye nezigulane

Namhlanje, ishishini lokutya linemvume yokusebenzisa iimveliso ezithile eziqulethe izixhobo zengqolowa, i-soybean kunye nee-oilseeds. Zingatholakala kwi-syrups, ufulawa, ioli, isitashi. Ezi ziseko zisetyenziselwa kwimimandla emikhulu yokuveliswa kweemveliso ezininzi, ukusuka kwiikuki, ukutya kwezingane, i-sausages kunye ne-sauces zokugqiba. Mhlawumbi asiyi kuqaphela ukutshintsha kwezofuzo ezibangelwa kukutya okunjalo, kodwa abazukulu bethu baya kubonakala baziva. Kwiibhubhoratri ezijikeleze ihlabathi, iimvavanyo ziqhubeka nezilwanyana ezichaphazelekayo kwezi zintengiselwano. Iziphumo zophando zibonisa ukuba ukungabikho kwengqondo kukhula ngexesha elide, kwaye ukuphindaphindiweyo kwezigulo kwizizukulwana ezilandelayo kwandisa amawaka amaninzi. Kukwafanelekile ukuba uqaphele ukuba iziganeko ezinokuthi zenzeke kwimveliso ethile. Ngokomzekelo, kwi-cream ye-stale, i-bhotela, amaqanda, amaqanda, i-compound yenziwa, ijika ibe yinto eguqukileyo. Ukuba inyama iphekwe kwiphunga layo, le nkqubo iyenzeka.

Amanyathelo okukhusela

Emva kokuba sifunde ukuba ihlabathi lethu lizele izigulane, kubonakala ngathi asinamandla. Kodwa eneneni, le ngcaciso inceda ukuba uqaphele ngakumbi xa ukhetha ukutya. Ukongezelela, ungayihoyi ezinye zeengcebiso. Ungalokothi udle ukutya okubi; Xa udibanisa neekhemikhali zendlu, sebenzisa iiglavu zerobhoki; Zama ukula ukudla okunamayeza kunye nama-conservative; Ukunciphisa ukusetyenziswa kweesekese. Sebenzisa xa upheka i-ginger, i-parsley, isardard, isitshalo seqanda, i-anyanisi, i-pepper, i-cilantro, iklabishi, ii-apula kunye netiyi eziluhlaza-ezi zinto zinciphisa impembelelo ye-mutagens.
