Pob ntses muaj ampullae ntawm Lorenzini?
1.12. 3.2 Qauv. Tus qauv ntawm cov khoom siv tsawg zaus ampullary yog lub ampullae ntawm Lorenzini, ib hom electroreceptor thawj zaug tau piav qhia ntau pua xyoo dhau los (Lorenzini, 1678) thiab tam sim no paub tias yog feem ntau rau txhua tus ntses cartilaginous.
Lub cev twg muaj ampulla ntawm Lorenzini?
Lub Ampullae ntawm Lorenzini yog cov khoom siv tshwj xeeb hauv lub cev hu ua electroreceptors, qhov chaw uas lawv tuaj yeem tsim lub network ntawm cov mucus-filled pores. Lawv feem ntau pom muaj nyob rau hauv cov ntses cartilaginous (sharks, rays, thiab chimaeras);txawm li cas los xij, lawv kuj pom muaj nyob hauv basal actinopterygians xws li reedfish thiab sturgeon.
Do lampreys muaj ampullae ntawm Lorenzini?
Tag nrho cov dej vertebrates-cyclostomes (piv txwv li, lampreys), ntses, thiab amphibians-muaj nyob rau hauv lawv… ua electroreceptors hu ua ampullae ntawm Lorenzini.
Dab tsi yog ampulla ntawm Lorenzini hauv Scoliodon?
Ampullae ntawm Lorenzini yog ib lub network ntawm electroreceptors, lub cev muaj zog uas kuaj pom hluav taws xob hauv dej, pom hauvchondrichthyes (sharks, rays, thiab chimaeras). Lub ampullae yog ib tug series ntawm symmetrical pores, concentrated nyob ib ncig ntawm lub snout thiab lub qhov ntswg, txuas nrog gel-filled canals.

Cov khoom xyaw twg hauv qab no ua cov tshuaj tsw qab hauv cov tshuaj txhuam hniav?
Sodium lauryl sulfate (SLS) yog surfactant feem ntau siv. YPuas yog tshuaj txhuam hniav puas yog surfactant? Surfactants. Ntau, txawm tias tsis yog tag nrho, tshuaj txhuam hniav muaj sodium lauryl sulfate (SLS) lossis lwm yam surfactants (detergents).
Ntawm qhov twg ntawm cov ces kaum hauv qab no yog cov haujlwm cosecant tsis tau txhais?
Qhov tseeb, tus nqi xa rov qab los ntawm kev ua haujlwm cosecant rau lub kaum sab xis ntawm xoom degrees lossis ib puas yim caum degrees yog suav tias yog tsis tau txhais, txij li qhov sib npaug csc (θ)= 1 / sin θ ) yuav suav nrog kev faib los ntawm xoom.
Puas yog ntses ntses ntse dua ntses ntses?
Octopuses manipulate objects zoo dua dolphins ua. Lub octopus muaj lub hlwb loj tshaj plaws ntawm txhua tus invertebrate, thiab ib qho ntawm peb feem tsib ntawm nws cov neurons nyob hauv nws cov tentacles. Raws li ntses taub ntswg ntev tsis muaj caj npab, qhov no yeej ua rau octopuses ib ceg loj.
Ntawm twg ntawm cov ces kaum hauv qab no yog cov haujlwm secant tsis tau txhais?
Qhov tseeb, tus nqi xa rov qab los ntawm kev ua haujlwm secant rau ib lub kaum sab xis ntawm cuaj caum degrees lossis ob puas thiab xya caum degrees yog suav tias yog tsis tau txhais, txij li qhov sib npaug sec (θ)= 1 / cos θ ) yuav suav nrog kev faib los ntawm xoom.
Puas yog cov ntses liab ntses nyob hauv Atlantic tuaj yeem ua liaj ua teb?
Farmed Atlantic salmon yog hatched, tsa thiab sau nyob rau hauv kev tswj hwm, thiab muaj tshiab txhua xyoo, feem ntau yog tus nqi qis dua cov ntses qus. Ua liaj ua teb-tsawg Atlantic salmon tau tsa thiab sau qoob loo raws li kev tswj xyuas uas muab cov ntses ib xyoos ib zaug.
