Ua kom pom qhov no, dab tsi yog qhov hla ntawm lub square?
Hla ntu . A hla ntu yog cov duab peb tau txais thaum txiav ncaj los ntawm ib yam khoom. Cov hla ntu ntawm cov khoom no yog daim duab peb sab. Nws zoo li kev pom rau sab hauv ntawm ib yam dab tsi uas tau txiav los ntawm nws.
Kuj Paub, dab tsi yog qhov cross section ntawm ib daim duab plaub? Yam khoom yog ib txoj cai duab plaub prism. Qhov siab tshaj plaws ntawm "sab" ntawm a hla ntu sib npaug ntawm cov ntsej muag (surfaces) ntawm cov khoom. Txij li thaum duab plaub prism qhia saum toj no muaj 6 lub ntsej muag, a hla ntu ntawm cov khoom ntawd yuav muaj ntau tshaj 6 sab.
Nyob rau hauv no txoj kev, koj yuav nrhiav tau qhov cross sectional cheeb tsam ntawm ib tug square?
Hla - Thaj Chaw of a Rectangular Solid Lub ntim ntawm cov khoom duab plaub, suav nrog lub voos xwmfab, yog qhov cheeb tsam ntawm nws lub hauv paus (ntev lub sij hawm dav) muab los ntawm nws qhov siab: V = l × w × h. Yog li ntawd, yog tias a hla ntu yog parallel rau saum lossis hauv qab ntawm cov khoom, lub cheeb tsam ntawm ntoo khaub lig - ntu yog lx w.
Lub cheeb tsam ntawm cross section yog dab tsi?
Hla ntu ntu yog ib cheeb tsam ntawm ib yam khoom yog tias koj saib nws li 2D khoom. Piv txwv li, xav txog ib lub pob zoo kawg nkaus.

Yuav ua li cas thiaj ua tau tus ntoo khaub lig?
Test crosses yog siv los kuaj ib tus neeg lub genotype los ntawm kev hla nws nrog ib tus neeg paub txog genotype. Cov tib neeg uas qhia txog cov phenotype recessive yog paub tias muaj homozygous recessive genotype. Lub phenotypically dominant kab mob yog tus neeg nyob rau hauv nqe lus nug nyob rau hauv ib tug xeem cross
Yuav ua li cas koj thiaj nrhiav tau tus nqi ntawm tus qauv txhais tau tias?
Qhov xav tau tus nqi ntawm tus qauv txhais tau tias yog cov pej xeem txhais tau tias, thiab SE ntawm tus qauv txhais tau tias yog SD ntawm cov pej xeem, muab faib los ntawm lub hauv paus square ntawm tus qauv loj
Yuav ua li cas koj tu rau tus ntoo khaub lig hlau begonia?
Nyiam ib nrab ntxoov ntxoo thiab organically nplua nuj, moist tab sis zoo-drained xau. Qhov no begonia yuav tsum muaj cov av noo siab thaum lub sij hawm loj hlob. Cia cov av qhuav ntawm watering thiab tsis txhob overwatering vim nws yuav ua rau cov kab mob fungal los yog rot. Propagate los ntawm noob, nplooj cuttings los yog seem ntawm rhizome
Yuav ua li cas koj ua tus ntoo khaub lig xeem?
Kev xeem hla kev koom nrog kev yug me nyuam rau tus neeg hauv nqe lus nug nrog lwm tus neeg uas qhia txog qhov tsis zoo ntawm tib yam. Kev txheeb xyuas qhov sib npaug ntawm cov xeeb ntxwv thiab cov xeeb ntxwv txiav txim siab seb tus neeg hauv nqe lus nug yog homozygous dominant lossis heterozygous
Yuav ua li cas koj nrhiav tau qhov chaw ntawm lub voj voog nyob rau hauv ib tug conic seem?
Tus nqi ntawm r yog hu ua 'radius' ntawm lub voj voog, thiab qhov taw tes (h, k) hu ua 'center' ntawm lub voj voog. (h, k) = (0, 0), ces qhov sib npaug simplifiesto x2 + y2 = r2
