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?
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.
Dab tsi ntawm cov hauv qab no yog tus yam ntxwv ntawm Anemophily?
Tus yam ntxwv ntawm cov paj anemophilous - txhais
Paj yog me thiab tsis pom zoo. Qhov tsis tseem ceeb yog qhov tsis muaj lossis txo qis. Cov paj tsis muaj xim, tsis muaj ntxhiab thiab nectarless. Yog cov paj tsis sib xws, cov txiv neej paj muaj ntau dua.
Qhov twg hauv qab no yog kev hloov pauv rau Entomophily?
Entomophilous paj qhia qee qhov kev hloov pauv tshwj xeeb uas muaj raws li hauv qab no: Lawv muaj xim ci ntsa iab kom nyiam kab. Lawv dais nectaries uas tsim nectar uas yog noj los ntawm kab. Lawv muaj cov paj ntoos nplaum nplaum thiab cov nplaum nplaum nplaum kom nws yooj yim lo rau ntawm ko taw ntawm kab.
Qhov twg hauv qab no yog piv txwv ntawm Anemophily?
Oak, chestnut, willow thiab elm ntoo, nplej, pob kws, oats, mov, thiab nettle yog piv txwv ntawm anemophilousnroj tsuag.
Pom zoo:
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 tsis yog kev hloov pauv rau anemophily?
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?
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?
