Dhau li ntawm no, dab tsi yog radially symmetrical lub cev?
Radial symmetry yog kev npaj ntawm lub cev qhov chaw nyob ib ncig ntawm lub hauv paus axis, zoo li rays ntawm lub hnub los yog tej daim nyob rau hauv ib lub ncuav. Radially symmetrical tsiaj muaj qhov saum toj thiab hauv qab, tab sis tsis muaj sab laug thiab sab xis, lossis pem hauv ntej thiab nraub qaum. Radial symmetry : Qee cov kab mob, xws li hiav txwv anemones (phylum Cnidaria), muaj radial symmetry.
Ib sab saum toj no, dab tsi yog 3 hom symmetry hauv cov tsiaj? Tsiaj tuaj yeem raug cais los ntawm peb hom ntawm lub cev txoj kev npaj symmetry : radial symmetry , ob tog symmetry , thiab asymmetry.
Ib yam li ntawd, tsiaj txhu dab tsi yog symmetrical?
Tsis yog, txhua tus tsiaj tsis sib haum, thiab ntawm no yog qee qhov piv txwv zoo tshaj plaws:
- Ntau yam crabs. Feem ntau nto moo, Fiddler Crabs.
- Antlered tsiaj. Feem ntau cov khib ntawm moose, elk lossis mos lwj txawv ntawm ib sab dua li lwm qhov.
- Cov ntses tiaj tus, zoo li Flounder.
- Narwhals.
- Crossbill & Wrybill.
Qhov twg phyla muaj radial symmetry?
cnidaria

Tus yam ntxwv twg yog qhia los ntawm txhua yam muaj sia?
Hmoov zoo, biologists tau tsim cov npe ntawm yim yam ntxwv sib koom los ntawm txhua yam muaj sia. Cov yam ntxwv yog qhov zoo lossis qhov zoo. Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution
Dab tsi yog qhov txawv ntawm tus tsiaj transgenic thiab tus tsiaj cloned?
Qhov no puas pab tau? Yog · Tsis yog
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Koj tuaj yeem qhia tau li cas yog tias kev sib raug zoo yog symmetrical?
Ib qho kev sib raug zoo yog qhov sib luag yog tias, peb pom tias rau txhua qhov txiaj ntsig ntawm a thiab b: a R b implies b R a. Kev sib raug zoo ntawm kev sib npaug dua yog symmetrical. Yog tias x = y, peb tuaj yeem sau tias y = x thiab
Qhov twg hauv qab no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum cellular, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution
