Torsion tso cai rau ko taw kom thim rov qab tom qab lub taub hau kom tiv thaiv lub taub hau zoo dua. DETORSION . Detorsion yog thim rov qab ntawm torsion uas tshwm sim thaum lub sij hawm evolution plhaub ploj los yog ib hom plhaub evolves uas muaj qhov qhib rau sab nraud. Hauv cov xwm txheej zoo li no, kev sib tw ntawm visceral loj yog tsis tsim nyog.

Nyob rau hauv tas li ntawd, dab tsi yog ib tug mantle kab noj hniav?

Cov mantle kab noj hniav yog ib qho tseem ceeb ntawm molluscan biology. Qhov no kab noj hniav yog tsim los ntawm cov mantle tiab, ob npaug ntawm mantle uas encloses ib qhov chaw dej. Qhov chaw no muaj mollusc's gills, qhov quav, osphradium, nephridiopores, thiab gonopores. Cov mantle kab noj hniav ua hauj lwm raws li ib tug ua pa chamber nyob rau hauv feem ntau molluscs.

Ib sab saum toj no, thaum lub sij hawm kev loj hlob puas torsion tshwm sim nyob rau hauv gastropod molluscs? Torsion yog kev sib hloov ntawm visceral loj thiab ko taw 180 degrees nrog rau lub taub hau thiab ko taw, thiab yog ib tug tshwj xeeb synapomorphy ntawm niaj hnub gastropods . Torsion tshwm sim thaum lub sij hawm kev loj hlob nyob rau hauv tag nrho gastropods , feem ntau nyob rau hauv lub lig veliger theem. Txawm li cas los xij, qee qhov gastropods ua tsis nyob twj ywm thaum ua neeg laus.

Hauv qhov no, lub plhaub coiling yog dab tsi?

coiling Hauv ntau lub univalve thiab bivalve molluscs (Mollusca) lub plhaub yog kauj . Cov tsos mob yog pom zoo tshaj plaws ntawm gastropods (Gastropoda) thiab cephalopods (Cephalopoda), qhov uas nws pom tseeb tias cov plhaub yog ib tug hollow cone, coil mus txog qhov ntau dua lossis tsawg dua.

Yuav ua li cas gastropods kom tsis txhob fouling?

Txij li cov kab mob ntawm lub mantle kab noj hniav (osphradia) yuav yuav zoo dua cov qauv dej thaum tig mus rau hauv kev taw qhia ntawm kev mus los, lub taub hau ua tau raug rho tawm mus rau hauv lub plhaub. Qhov poob ntawm txoj cai gill ua rau nws ua tau rau txo cov teebmeem ntawm fouling.

Dab tsi yog qhov txawv ntawm zoology?

Qee qhov tseem ceeb ntawm cov txheej txheem zoology yog: anthrozoology, ecology, embryology, thiab physiology. Antrhozoology yog kev kawm txog kev sib cuam tshuam ntawm tib neeg thiab tsiaj txhu. Ecology yog txoj kev kawm txog cov tsiaj txhu cuam tshuam li cas thiab ua rau lawv ib puag ncig

Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?

Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%

Dab tsi yog induction hauv zoology?

Embryonic induction piav qhia txog cov txheej txheem embryonic uas ib pawg ntawm cov hlwb, cov ntaub so ntswg inducing, directs txoj kev loj hlob ntawm lwm pab pawg neeg ntawm cov hlwb, cov ntaub so ntswg teb. Induction directs txoj kev loj hlob ntawm ntau yam ntaub so ntswg thiab kabmob nyob rau hauv feem ntau tsiaj embryos; Piv txwv li, lub qhov muag lens thiab lub plawv

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?

Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
