Gemmule . Ib qho asexually tsim loj ntawm cov hlwb, uas yog muaj peev xwm ntawm kev loj hlob mus rau hauv ib tug tshiab kab mob los yog mus rau hauv ib tug neeg laus cov dej qab zib sponge yog hu ua a Gemmule . Asexual reproduction yog tsuas yog nqa tawm los ntawm budding thiab kuj los ntawm gemmulation. Internal buds, uas raug tsim los ntawm cov dej tshiab yog npe as gemmules
Ntawm no, Gemmule muab piv txwv li cas?
Gemmules yog cov buds sab hauv pom nyob rau hauv daim txhuam cev thiab koom nrog hauv kev yug me nyuam asexual. Nws yog ib qho asexually reproduced loj ntawm cov hlwb uas muaj peev xwm ntawm kev loj hlob mus rau hauv ib tug tshiab kab mob, uas yog, ib tug neeg laus daim txhuam cev. Piv txwv yog Spongilla lacustris.
Tom qab ntawd, lo lus nug yog, vim li cas Gemmules pom feem ntau hauv cov sponges dej tshiab? Hauv cov dej tshiab , gemmules tuaj yeem muaj sia nyob ib puag ncig ib puag ncig xws li kev hloov pauv ntawm qhov kub thiab txias. Lawv ua hauj lwm rau recolonize lub vaj nyob ib puag ncig tej yam kev mob stabilize. Gemmules muaj peev xwm txuas rau lub substratum thiab tsim ib qho tshiab daim txhuam cev.
Ntxiv mus, nyob rau hauv uas marine daim txhuam cev Gemmule tsim tshwm sim?
Asexual reproduction nyob rau hauv daim txhuam cev tshwm sim los ntawm budding, los ntawm sab nraud los yog sab hauv buds. Internal buds hu ua gemmules . Ob hom buds loj hlob mus rau hauv tshiab daim txhuam cev.
Lub luag haujlwm ntawm Archaeocytes yog dab tsi?
Archaeocytes tseem ceeb heev rau kev ua haujlwm ntawm daim txhuam cev. Cov hlwb no yog totipotent, uas txhais tau hais tias lawv tuaj yeem hloov mus rau tag nrho lwm hom sponge hlwb. Archaeocytes noj thiab zom cov zaub mov uas ntes tau los ntawm choanocyte dab tshos thiab thauj cov as-ham mus rau lwm lub hlwb ntawm daim txhuam cev.

Koj txhais li cas los ntawm inertia ntawm kev coj?
Inertia ntawm kev taw qhia txhais tau tias yog qhov tsis muaj peev xwm ntawm lub cev lossis khoom siv los hloov nws txoj kev taw qhia ntawm nws tus kheej. Qhov ntawd yog sab nraud quab yuam yuav tsum tau hloov nws txoj kev taw qhia. Qhov no yog vim inertia ntawm kev coj
Koj txhais li cas los ntawm kev them nyiaj ntawm tRNA?
Kev them nyiaj yug tRNA. Ua ntej ib qho amino acid tuaj yeem muab tso rau hauv ib qho kev loj hlob ntawm polypeptide, nws yuav tsum xub muab txuas mus rau lub molecule hu ua hloov RNA, los yog tRNA, nyob rau hauv ib tug txheej txheem hu ua tRNA them. Tus nqi tRNA yuav nqa cov activated amino acid mus rau ribosome
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Yuav ua li cas koj pom tus qauv enthalpy ntawm tsim los ntawm combustion?
Tus qauv enthalpy ntawm cov tshuaj tiv thaiv (Δ Horxn) tuaj yeem xam los ntawm cov lej ntawm cov qauv enthalpies ntawm kev tsim cov khoom (txhua qhov sib npaug los ntawm nws cov stoichiometric coefficient) rho tawm cov lej ntawm cov qauv enthalpies ntawm kev tsim cov reactants (txhua qhov sib npaug los ntawm nws. stoichiometric coefficient) - "cov khoom
Koj txhais li cas los ntawm geometric tsim?
Geometrical design (GD) yog ib ceg ntawm kev suav geometry. Nws cuam tshuam nrog kev tsim kho thiab kev sawv cev ntawm cov qauv dawb-dawb nkhaus, qhov chaw, lossis ntim thiab muaj feem cuam tshuam nrog cov qauv geometric. Geometric qauv tuaj yeem tsim rau cov khoom ntawm txhua qhov ntev hauv txhua qhov chaw geometric
