Hom ntawm symmetry
Muaj peb hom qauv: Radial symmetry : Lub cev zoo li lub ncuav qab zib. Ob tog symmetry : Muaj axis; ntawm ob sab ntawm lub axis lub cev zoo li roughly tib yam. kheej kheej symmetry : Yog lub cev raug txiav nws center, qhov tshwm sim zoo ib yam.
Kuj nug, dab tsi yog symmetry thiab nws hom?
Kev txhais ntawm Symmetry Rau ob yam khoom yuav tsum symmetrical , lawv yuav tsum yog tus tib qhov loj thiab cov duab, nrog rau ib yam khoom muaj qhov sib txawv orientation los ntawm tus ua ntej. Kuj muaj symmetry hauv ib yam khoom, xws li lub ntsej muag. Muaj peb yam yooj yim hom ntawm symmetry : kev sib hloov symmetry , kev xav symmetry , thiab point symmetry.
Ib tug kuj nug, dab tsi yog 4 hom symmetry? Plaub yam tseem ceeb ntawm qhov symmetry no yog kev txhais lus, kev sib hloov , xav txog , thiab glide xav txog.
Hais txog qhov no, koj txhais li cas los ntawm symmetry hauv biology?
Symmetry hauv biology yog qhov sib npaug ntawm qhov sib npaug ntawm lub cev lossis cov duab hauv lub cev ntawm cov kab mob. Hauv xwm thiab biology , symmetry yog ib txwm kwv yees. Lub cev npaj ntawm feem ntau cov kab mob multicellular nthuav tawm qee hom symmetry , txawm tias radial, ob sab, lossis kheej kheej.
Dab tsi yog hom symmetry hauv qhov xwm txheej?
Ob lub ntsiab hom symmetry yog reflective thiab rotational. Reflective, los yog kab, symmetry txhais tau hais tias ib nrab ntawm ib daim duab yog daim iav duab ntawm ib nrab (xav txog ib tug npauj npaim tis). Tib neeg, kab, thiab tsiaj txhu txhua tus qhia ob sab symmetry . Txiv neej yog ib txwm attracted rau symmetry.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog distillation thiab nws hom?
Qee yam tseem ceeb ntawm distillation muaj xws li: Fractional distillation. Chav distillation. Nqus distillation. Cua-sensitive nqus distillation
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Dab tsi yog symmetry thiab cov qauv hauv kev yees duab?
Peb nyob ib puag ncig los ntawm symmetry thiab cov qauv, ob qho tib si ntuj thiab tib neeg tsim. Lwm txoj hauv kev zoo los siv lawv yog txhawm rau ua kom muaj qhov sib luag lossis cov qauv hauv qee txoj kev, qhia qhov nro thiab focal point rau qhov chaw
