Ib adaptive hluav taws xob tshwm sim thaum ib pawg los yog me me ntawm cov poj koob yawm txwv hom sai sai diversifies mus rau ib tug loj tus naj npawb ntawm cov xeeb leej xeeb ntxwv hom. Ntawm yam uas tuaj yeem ua rau ib adaptive hluav taws xob , ecological lub sij hawm yog tej zaum foremost.
Ua raws li qhov xav tau, qee qhov piv txwv ntawm kev hloov hluav taws xob hloov pauv li cas?
Qhov tseeb, ntau classic piv txwv ntawm kev hloov hluav taws xob koom nrog cov Islands tuaj lossis pas dej; tseem ceeb piv txwv suav nrog Darwin's finches ntawm tus Galapagos, honeycreeper noog thiab silversword nroj tsuag ntawm Hawaii, thiab cichlid ntses ntawm pas dej Malawi thiab Victoria hauv Africa.
Qhov thib ob, kev hloov pauv hluav taws xob cuam tshuam li cas rau cov nroj tsuag? Hauv cov lus nug saum toj no, adaptive hluav taws xob tso cai nroj tsuag txhawm rau sau cov chaw nyob sib txawv (niches) uas pom hauv av thiab nthuav tawm sai heev.
Dhau li ntawm no, dab tsi yog qhov cuam tshuam ntawm kev hloov hluav taws xob?
Ib Adaptive Radiation tshwm sim thaum ib hom pom nws tus kheej nyob rau hauv ib tug dav ecological niche nrog ob peb tus neeg sib tw. Qhov no tso cai rau cov evolution sai sai ntawm cov tsiaj muaj feem xyuam raws li thawj lub niche tau sau, thiab raws li pab pawg pib siv cov peev txheej ntau dua thiab tshwj xeeb.
Vim li cas thiaj hloov hluav taws xob tshwm sim ntawm cov Islands tuaj?
Kev piav qhia: Kev hloov hluav taws xob , los yog thaum cov kab mob tshiab muaj kev sib txawv sai heev vim muaj kev cuam tshuam ib puag ncig tshiab, lub cib fim, lossis cov peev txheej, tshwm sim Nyob rau hauv cov xwm txheej xws li tom qab ib tug loj extinction, thaum lub pas dej tau tsim tshiab, tom qab ib tug volcanic tawg heev hloov lub toj roob hauv pes, los yog tsim ntawm tshiab. cov kob.

Tus kws tshaj lij hluav taws xob puas tuaj yeem ua tus kws kho hluav taws xob?
Koj tuaj yeem tau txais koj pib nrog tsawg asatwo-xyoo Associate's degree thiab ntawv pov thawj los ntawm AmericanRegistry of Radiologic Technologists. Ntau yam rad techspursueradiology tshwj xeeb, xws li mammography. Lwm tus txiav txim siab ntxiv lawv txoj haujlwm los ntawm kev rov qab mus rau tsev kawm ntawv los ua tus kws kho mob
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Kev hloov hluav taws xob hluav taws xob yog dab tsi?
Lub zog hluav taws xob tuaj yeem hloov mus rau ntau yam ntawm lwm hom zog. Qhov no yog tsim los hloov hluav taws xob hluav taws xob mus rau lub zog suab. Raws li cov hluav taws xob dhau los ntawm cov xov hlau, Circuit Court boards thiab lwm yam khoom, qee qhov ntawm cov hluav taws xob qub tau hloov mus rau hauv lub zog hluav taws xob
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
