Tsuas yog ob peb pawg tsiaj tso tawm radial symmetry , thaum asymmetry yog ib qho tshwj xeeb ntawm phyla Porifera (sponges).
Yog li ntawd, qhov txawv ntawm asymmetry radial symmetry thiab ob sab symmetry yog dab tsi?
Ob tog vs. Ob sab symmetry txawv ntawm radial symmetry . Nyob rau hauv tas li ntawd, lub radially symmetrical Cov kab mob zoo ib yam li lub ncuav qab zib, qhov twg txhua daim yuav luag zoo tib yam txawm tias lawv tsis muaj sab laug lossis sab xis; Hloov chaw, lawv muaj qhov saum npoo thiab hauv qab.
Ib yam li ntawd, cov ntses hnub qub puas radially symmetrical? Radial symmetry txhais tau hais tias lub cev yog lub hub, zoo li lub tsheb kauj vab log, thiab tentacles yog spokes los ntawm nws (xav txog ib tug ntses hnub qub ). Raws li larvae, echinoderms yog ob sab symmetrical . Thaum lawv loj tuaj, lawv ua radially symmetrical . Feem ntau cov neeg laus echinoderms nyob rau hauv qab ntawm dej hiav txwv pem teb.
Xav txog qhov no, dab tsi yog asymmetrical lub cev symmetry?
asymmetrical : muaj kev tsis sib haum xeeb ntawm qhov chaw; nthuav tawm tsis muaj qauv. ob tog symmetry : muaj kev sib npaug ntawm qhov chaw ( symmetry ) hais txog lub dav hlau ntsug khiav ntawm lub taub hau mus rau tus Tsov tus tw. radial symmetry : ib form symmetry nyob qhov twg qhov zoo tib yam yog teem nyob rau hauv ib ncig zam nyob ib ncig ntawm ib tug central axis.
Puas yog Hydra radially symmetrical?
Hydras , zoo li txhua tus cnidarians, tso saib radial symmetry . Qhov no txhais tau hais tias lawv tau tsim nrog ib qho txawv sab saum toj thiab hauv qab, tab sis tsis muaj qhov txawv ntawm sab laug lossis sab xis. Nws yog ua tau rau lub hydra ua ua kom pom ob hom symmetry tib lub sijhawm, raws li tetrameral symmetry tuaj yeem tsim nyob ib puag ncig ib radial npaj.
Pom zoo:
Lub hauv paus ntawm symmetry yog dab tsi?
Thiab ncaj qha los ntawm Latin symmetria, los ntawm Greek symmetria 'kev pom zoo nyob rau hauv qhov ntev, vim kev faib ua feem, kev npaj,' los ntawm symmetros 'muaj ib qho kev ntsuas, txawm, proportionate,' los ntawm assimilated daim ntawv ntawm syn- 'ua ke' (saib syn-) + metron ' ntsuas' (los ntawm PIE hauv paus * me- (2) ' ntsuas')
Dab tsi yog symmetry thiab nws hom hauv biology?
Hom symmetry Muaj peb hom qauv: Radial symmetry: Lub cev zoo li lub ncuav qab zib. Ob sab symmetry: Muaj ib qho axis; ntawm ob sab ntawm lub axis lub cev zoo li roughly tib yam. Spherical symmetry: Yog tias lub cev raug txiav los ntawm nws qhov chaw, qhov tshwm sim zoo ib yam
Dab tsi yog cov ntsiab lus ntawm crystal symmetry?
Yog li, cov siv lead ua no muaj cov ntsiab lus hauv qab no: 1 - 4-fold rotation axis (A4) 4 - 2-fold rotation axes (A2), 2 txiav lub ntsej muag & 2 txiav cov npoo. 5 daim iav dav hlau (m), 2 txiav hla lub ntsej muag, 2 txiav los ntawm cov npoo, thiab ib qho txiav kab rov tav los ntawm qhov chaw
Compound symmetry yog dab tsi?
Piv txwv li, cov qauv Compound Symmetry tsuas yog txhais tau hais tias txhua qhov sib txawv yog sib npaug rau ib leeg thiab txhua qhov sib txawv yog sib npaug. Qhov ntawd yog nws. Txhua qhov sib txawv thiab txhua qhov sib txawv yog txawv kiag li thiab tsis muaj kev cuam tshuam rau lwm tus. Muaj ntau, ntau cov qauv sib txawv
Dab tsi yog rotational symmetry hauv geometry?
Rotational Symmetry. Ib daim duab muaj Rotational Symmetry thaum nws tseem zoo li qub tom qab qee qhov kev sib hloov (tsawg dua ib qho tig tag nrho)
