Coniferous ntoo muaj ntiav heev keeb kwm uas nthuav tawm thoob plaws ib cheeb tsam loj, tso cai rau lawv los so hauv dej nyob ze ntawm qhov chaw. Qhov ntiav keeb kwm kuj yog ib tug zoo kev yoog raws rau nyob rau hauv cov av tsis zoo los yog pob zeb.
Yog li ntawd, hom keeb kwm twg conifers muaj?
Cov hauv paus system feem ntau yog ntiav, fibrous thiab kis tau. Qee qhov loj dua conifers yuav muaj loj dua keeb kwm tshwm sim hauv av, ua rau nws nyuaj rau mow (txawm hais tias nyom yuav tsis tshua loj hlob nyob rau ntawd), los yog tib neeg tuaj yeem hla lawv.
Tsis tas li ntawd, cov ntoo conifer puas muaj cov hauv paus hniav sib sib zog nqus? Cov keeb kwm ntawm Leylandi Conifer tuaj yeem sib kis tau deb heev, tshwj xeeb tshaj yog siab dua ntoo . Qhov no tuaj yeem ua rau muaj teeb meem ntau rau cov khoom nyob sib ze vim tias lawv tshem tawm cov av noo, ua rau nws qhuav. Txawm tias conifer paus yog ntiav, lawv kis mus txog xya zaus raws li lawv loj hlob.
Kuj nug, yuav ua li cas conifers yoog rau lawv ib puag ncig?
Teb: ib ntawm tus tseem ceeb tshaj adaptations ntawm conifer ntoo yog tus tuab waxy cuticle uas waterproof tus nplooj. Ib ntawm tus feem ntau notable adaptations ntawm conifer ntoo yog tus muaj nplooj zoo li rab koob. Cov nplooj no yog yoog raws kom ciaj sia nyob rau hauv harsher thiab txias dua piv rau broad nplooj.
Yuav ua li cas sib sib zog nqus ntawm tsob ntoo conifer roots?
loj tshaj plaws ntoo yuav muaj feem ntau ntawm lawv keeb kwm nyob rau sab saum toj 18 mus rau 24 ntiv tes, txawm li cas los xij raws li hom av. qhov zoo dua tag nrho cov kua dej, feem ntau cov tob dua thiab nthuav dav ntxiv hauv paus system.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Cov kab mob dab tsi nyob hauv cov hauv paus hniav ntawm cov nroj tsuag?
Cov kab mob hauv paus muaj txiaj ntsig txhawb cov nroj tsuag kev loj hlob thiab muab kev tiv thaiv los ntawm cov kab mob. Lawv feem ntau yog rhizobacteria uas yog Proteobacteria thiab Firmicutes, nrog ntau yam piv txwv los ntawm Pseudomonas thiab Bacillus genera. Rhizobium hom colonize legume keeb kwm tsim cov qauv nodule
Yuav ua li cas koj pom cov hauv paus hniav ntawm ib qho kev sib npaug algebraically?
Cov hauv paus hniav ntawm ib qho kev sib npaug plaub yog muab los ntawm: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Sau lub quadratic nyob rau hauv daim ntawv ntawm ax^2 + bx + c = 0. Yog hais tias qhov sib npaug yog nyob rau hauv daim ntawv y = ax^2 + bx + c, tsuas yog hloov lub y nrog 0. Qhov no yog ua li cas vim lub hauv paus ntawm lub equation yog cov nqi uas qhov y axis sib npaug rau 0
Kuv yuav ua li cas thiaj paub yog tias kuv cov txhuam hniav yuav tsum tau hloov?
Raws li txoj cai dav dav, yog tias txhuam txhuam tau hnav txog li ib lub quarter ntiv tes ntev, nws yog lub sijhawm los hloov nws. Yog tias cov pa roj carbon (cov txhuam hniav yog qhov tseem ceeb ntawm cov pa roj carbon nrog lub caij nplooj ntoos hlav hlau) qhia pom tias muaj kev tawg, tawg, lossis hlawv, txhuam yuav tsum tau hloov
Vim li cas nws tseem ceeb heev uas yuav tsum xav txog ntau yam thaum txiav txim siab cov hauv paus hniav ntawm cov kab zauv polynomial?
Piv txwv li, tus naj npawb ntawm lub sij hawm ib tug muab polynomial sib npaug muaj ib lub hauv paus ntawm ib tug muab point yog lub multiplicity ntawm lub hauv paus. Qhov kev xav ntawm ntau qhov tseem ceeb yog qhov tseem ceeb kom suav tau kom raug yam tsis muaj kev qhia tshwj xeeb (piv txwv li, ob lub hauv paus suav ob zaug). Li no cov lus qhia, ' suav nrog ntau ntau'
