Nhanganyaya: Chalaza Chakavanzika
Kune vanhu vazhinji, chalaza yezai inoramba iri chakavanzika. Chimiro chidiki, chakaita setambo chinogona kuonekwa pakutsemuka kuvhura zai, asi chinobatsirei? Chalaza ingaita seisina kukosha, asi ine basa rakakosha mukukura nekuchengetedzeka kwe "embryo" mukati mezai. Muchinyorwa chino, tichaongorora anatomy yezai uye basa rechalaza.
Chii chinonzi Chalaza cheZai?
Chalaza itambo yakaita spiral, albumin-rich rich iyo inosungirira yolk kune membrane membrane kune chero kumagumo. Inowanikwa kumativi akatarisana ezai, uye inokwanisa kuonekwa sezviumbwa zviviri zvichena, zvine tambo pakutsemuka kuvhura zai. Chalaza haifaniri kuvhiringwa ne germinal disc, iyo iri pajoko uye ndipo panoitika fertilization.
Chalaza inoumbwa pakuumbwa kwezai mudumbu rehuku. Sezvo yolk inofamba ichidzika neoviduct, zvikamu zve albumen zvinowedzerwa kumativi ose. Iyo chalaza inoumbwa nekuda kwekumonyorora nekukochekera kwealbumen panguva iyi. Zai parinokandwa, chalaza inosungirira yolk panzvimbo uye inoita kuti isafambe zvakanyanya mukati mezai.
Kunzwisisa Anatomy yeZai
Kuti unzwisise zviri nani basa rechalaza, zvakakosha kuve nekunzwisisa kwekutanga kweanatomy yezai. Zai rine zvidimbu zvakati wandei, kutanga kubva kunze uye kufamba mukati: goko, shell membrane, air cell, albumen (kana chena zai), chalaza, uye yolk. Aya akaturikidzana anodzivirira uye anosimbisa "embryo" iri kukura mukati mezai.
Iyo shell inoumbwa ne calcium carbonate uye inopa chipingamupinyi chekudzivirira kubva mukukuvadzwa kwemuviri uye mabhakitiriya. The shell membrane inzvimbo yakatetepa inogara pakati pegoko ne albumen, uye inobatsira kuti zai risaoma. Sero remhepo rinowanikwa pasi pezai uye rinokura sezvo zai rinokura. Iyo albumen inopa manyuko emvura, mapuroteni, uye zvimwe zvinovaka muviri kumwana ari kukura, nepo yolk ine mafuta, mavhitamini, uye zvicherwa zvinokoshawo pakukura.
Basa reChalaza chii?
Chalaza ine mabasa akati wandei akakosha mukukura nekuchengetedzeka kwe embryo mukati mezai. Rimwe rebasa rayo guru nderokuchengetedza yolk panzvimbo uye kudzivirira kufamba-famba zvakanyanya mukati mezai. Izvi zvakakosha nekuti yolk ine chikafu chese chinodiwa ne "embryo" ichikura, uye kufamba zvakanyanya kunogona kukanganisa yolk kana kukanganisa kukura kwe "embryo".
Chalaza inobatsirawo kuisa "embryo" iyo germinal disc yakatarisa kumusoro. Izvi zvakakosha nekuti zvinoita kuti embryo iwane okisijeni kubva musero remhepo uye inobatsira kudzivirira iyo yolk kubva kunamira kune shell membrane. Pamusoro pezvo, chalaza inoshanda sechinhu chinokatyamadza, ichidzivirira "embryo" kubva pakuzununguka kana kukanganisa kunogona kuitika panguva yekutakura kana kubata.
Basa reChalaza muKubereka
Kunyange zvazvo chalaza risingabatanidzwi zvakananga mukuberekesa, rinokwanisa kuita basa pakuona kuti nhiyo inochochonya murume kana kuti mukadzi. The germinal disc, iyo iri pajoko, ine genetic material inozoratidza kuti nhiyo yacho irume here. Kana zai rikatenderedzwa panguva yekukandira, chalaza inogona kuita kuti germinal disc ishanduke, izvo zvinogona kukanganisa hutano hwemwana ari kukura.
Iyo Chalaza Inochengeta Embryo Yakachengeteka
Chalaza haingobatsiri chete kuchengetedza yolk panzvimbo, asi inodzivirirawo embryo inokura kubva mukukuvadza. Semuyenzaniso, kana zai rikadonhedzwa kana kurohwa, chalaza inoshanda sechinhu chinokatyamadza, ichideredza kukanganiswa kweembryo. Pamusoro pezvo, chalaza inobatsira kudzivirira mabhakitiriya kuti asapinde muzai, izvo zvinogona kukuvadza embryo kana kukanganisa.
Kuendesa Nutrient kuburikidza neChalaza
Chalaza haingosungiri yolk chete panzvimbo, asiwo inoshanda senzira yekuendesa kudya kunovaka muviri kumwana ari kukura. Sezvo iyo albumen inowedzerwa kutenderedza yolk, zvinovaka muviri zvakaita semapuroteni, zvicherwa, uye mvura zvinowedzerwawo. Zvokudya izvi zvinobva zvatakurwa kumwana ari kukura kuburikidza nechalaza.
Chalaza seChiratidzo cheKunaka Kwezai
Kuvapo kwechalaza yakagadzirwa zvakanaka inogona kuva chiratidzo chehutano hwezai. Chalaza yakagadzirwa zvakanaka inoratidza kuti zai rakakandwa nehuku ine hutano uye kuti yolk yakamira zvakanaka uye yakamiswa panzvimbo. Mazai ane chalaza isina kusimba anowanzova nehupenyu hurefu hwesherufu, sezvo asinganyanyi kukanganisa kana kusvibiswa panguva yekutakurwa nekuchengetwa.
Kukosha kweChalaza muCulinary Arts
Kunyange zvazvo chalaza ichiwanzobviswa pakubika nemazai, inogona kuva nemigumisiro pane chigadzirwa chekupedzisira. Semuenzaniso, kuvapo kwechalaza inooneka muzai rakaputirwa kunogona kuratidza kuti zai iri nyowani, sezvo chalaza ichida kuparara nekufamba kwenguva.
Mabatiro Akanaka Mazai neIntact Chalaza
Mazai ane chalaza isina kusimba anofanirwa kubatwa zvine hungwaru kudzivirira kukanganisa kumwana ari kukura embryo kana yolk. Pakutsemuka kuvhura zai, chalaza inofanira kubviswa pamwe chete nealbumen. Kana chalaza rikasiiwa, rinogona kukonzera kuti zai jena risanyatsogadzikana kana rorohwa kana kurohwa.
Mhedziso: Kukoshesa Chalaza
Kunyange zvazvo chalaza ichiita sechikamu chidiki uye chisingakoshi chezai, inotoita basa rakakosha mukukura nekuchengetedzeka kwe "embryo" mukati mezai. Kunzwisisa zvakaita zai uye kushanda kwechalaza kunogona kutibatsira kunzwisisa kuoma uye kunaka kwekugadzirwa kwezvinhu zvakasikwa. Ingave yakashandiswa muhunyanzvi hwekubika kana sechiratidzo chemhando yezai, chalaza chikamu chidiki asi chakakosha chezai chisingafanirwe kufuratirwa.
