Kev piav qhia: Cov lus tsis raug hais txog kev mob anemophily yog paj paj noob hlis yog lub teeb thiab nplaum. Anemophily los yog cua pollination yog ib hom ntawm pollination uas paj ntoos faib los ntawm cua.
Qhov twg hauv qab no yog kev hloov pauv rau Anemophily?
◆ Floral adaptations of anemophily yog -
Stamens muaj ntev filaments thiab nthuav tawm. Lawv pollen nplej yog qhuav, lub teeb yuag thiab powdery. Stigma ntawm anemophilous paj yog nplaum & feathery.
Dab tsi yog qhov hloov ntawm Hydrophilous nroj tsuag?
Cov paj hloov pauv ntawm cov paj hydrophilous yog: Paj tsis muaj xim, me me, tsis pom kev tsis muaj qab zib thiab tsw qab. Pollen nplej yog ntev, ribbon zoo li cov qauv uas nqa nrog dej tam sim no. Cov paj ntoos nplej yog lub teeb tab sis npog nrog siv quav ciab, txhawm rau tiv thaiv lawv los ntawm ntub dej.
Dab tsi ntawm cov hauv qab no yog cov yam ntxwv ntawm cov nroj tsuag anemophilous?
Dab tsi yog qee yam ntawm Anemophilous paj?
- Paj me.
- Lawv tsis muaj xim ntxim nyiam.
- Lawv tsis tso tshuaj tsw qab.
- Anthers muaj ntau yam.
- Tau paj paj ntau ntau los ua kom lub paj tawg loj heev los ntawm cua.
- KojSigma yog piav ntau heev, thiab nws feem ntau yog bifid thiab feathery.
Yuav ua li cas rau Anemophily?
ua tiavTeb: Anemophily los yog cua pollinationyog pollination uas cov paj ntoos nplej tau faib los ntawm cua. Yuav luag tag nrho cov gymnosperms yog anemophilous thiab yog li cov nyom thiab bushes.

Dab tsi ntawm cov hauv qab no yog kev hloov pauv ntawm pob txha mus rau bipedalism?
Kev yoog rau bipedalism suav nrog " stacking" feem ntau ntawm qhov hnyav ntawm lub cev hla thaj chaw me me nyob ib ncig ntawm qhov chaw ntawm lub ntiajteb txawj nqus(piv txwv li, lub taub hau saum lub hauv siab, uas yog saum lub pelvis, uas yog tshaj lub hauv caug, uas yog saum ko taw).
Dab tsi yog qhov hloov pauv thiab hloov pauv hloov pauv?
Point mutations hloov ib leeg nucleotide. Frameshift kev hloov pauv yog ntxiv lossis tshem tawm ntawm nucleotides uas ua rau muaj kev hloov pauv hauv kev nyeem ntawv. frameshift thiab point mutation yog dab tsi? Ib qho kev hloov pauv cuam tshuam rau ib khub hauv paus.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Dab tsi ntawm cov hauv qab no yog kev hloov pauv rau anemophily?
Floral adaptations for anemophily: (1) Paj yog me me thiab tsis pom zoo. (2) Paj tsis muaj xim ci, nectar thiab ntxhiab. (3) Cov paj yog ntsuab thiab me me los yog txo qis heev. Yuav ua li cas hauv qab no tsis yog kev hloov pauv rau Anemophily?
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
