Yog li ntawd, lub paub niche ntawm cov hom uas twb muaj lawm tuaj yeem hloov pauv thiab txawv ntawm qhov tseem ceeb niche.
Hauv qhov no, yuav ua li cas thaum niches sib tshooj?
Txoj cai tswjfwm tsis suav nrog kev sib tw hais tias ob hom tsis tuaj yeem nyob ua ke yog tias lawv nyob ib yam nkaus niche (kev sib tw rau cov peev txheej zoo ib yam). Ob hom uas niches sib tshooj tej zaum yuav hloov zuj zus los ntawm kev xaiv ntuj kom muaj qhov txawv dua niches , ua rau muaj kev faib khoom.
Dab tsi yog niche hauv biology?
A niche hais txog txoj hauv kev uas lub cev haum rau hauv zej zog ecological lossis ecosystem. Los ntawm cov txheej txheem ntawm kev xaiv ntuj, a niche yog qhov tshwm sim ntawm kev hloov pauv ntawm hom kab mob morphological (morphology hais txog cov kab mob hauv lub cev), physiological, thiab kev coj tus cwj pwm hloov mus rau nws ib puag ncig.

Koj txhais li cas los ntawm txoj kev sib tshooj sib tshooj?
Txheej txheem. Hauv kev xyaum, tus txheej txheem ntawm kev sib sau ua ke txhais tau hais tias peb muab cov lej tom qab ntawm txhua (lossis ib sab) los ntawm tus lej ntawm lwm tus, ua tau zoo hla cov ntsiab lus. peb tuaj yeem muab cov nqe lus ntawm txhua sab los ntawm tib tus lej thiab cov ntsiab lus yuav nyob sib npaug
Dab tsi yog qhov kev teeb tsa hluav taws xob dav dav ntawm SPD thiab F thaiv cov ntsiab lus?
Sau cov txheej txheem hluav taws xob sab nraud ntawm s-, p-, d- thiab f-block ntsiab. Element General sab nrauv hluav taws xob configuration p–block(metals & non metals) ns2np1–6, where n = 2 – 6 d–block(transition elements) (n–1) d1–10 ns0–2, where n = 4 – 7 f -block(internal transition elements) (n–2)f1–14(n–1)d0–10ns2, where n=6–7
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm kev nkag siab dav dav BSH thiab kev nkag siab nqaim NSH?
12) Dab tsi yog qhov txawv ntawm qhov dav-sensitive heritability (BSH) thiab nqaim-sense heritability (NSH)? A) BSH yog ib qho kev ntsuas ntawm cov noob uas cuam tshuam rau qhov zoo, thaum NSH yog ib qho kev ntsuas ntawm cov noob nrog cov teebmeem loj. B) NSH muaj feem xyuam rau ib leeg-gene yam nkaus xwb
Cov kab hluav taws xob sib tshooj puas tuaj yeem sib tshooj?
Cov rays tawm tsam yog ob lub rays uas ob qho tib si pib los ntawm ib qho kev taw qhia thiab tawm mus rau qhov sib txawv raws nraim. Vim yog qhov no, ob lub rays (QA thiab QB hauv daim duab saum toj no) tsim ib txoj kab ncaj nraim los ntawm qhov kawg Q. Thaum ob lub rays sib txawv, cov ntsiab lus A, Q thiab B yog collinear
