Ib qho tseem ceeb tshaj qhov cuam tshuam ntawm symmetry inphysics yog lub hav zoov ntawm kev txuag txoj cai. Rau txhua lub ntiaj teb txuas ntxiv symmetry -i.e., ib qho kev hloov ntawm aphysical system uas ua tib yam li txhua qhov chaw thiab txhua lub sijhawm - muaj ib qho kev cuam tshuam rau lub sijhawm ywj pheej kom muaj nuj nqis: aconserved charge.
Tsis tas li ntawd, vim li cas symmetry tseem ceeb hauv physics?
Nws yog ib qho kev nthuav dav ntawm txoj kev xav ntawm ib qho kev sib npaug, thiab koj tuaj yeem siv nws los muab qhov sib npaug. Symmetries yog immensely tseem ceeb vim txhua symmetry tuaj yeem hais tau raws li txoj cai kev txuag. Cov nyhuv no, vim yog Noether's theorem, tso cai rau koj kom pom cov kev cai tseem ceeb ntawm lub ntiaj teb.
Tsis tas li ntawd, vim li cas symmetry yog qhov tseem ceeb hauv lub neej niaj hnub? Symmetry yog ib yam uas peb saib nyob rau hauv ntau qhov chaw hauv peb lub neej txhua hnub txawm tsis pom nws. Nws yooj yim pom nyob rau hauv ntau yam txuj ci, vaj tse, thiab monuments. Natureuses symmetry ua tej yam zoo nkauj. Vim symmetry ib yam khoom, duab thiab saib zoo nkauj dua.
Ib yam li ib tug yuav nug, lub ntsiab lus ntawm symmetry hauv physics yog dab tsi?
Hauv physics , a symmetry ntawm lub cev lub cev yog lub cev lossis kev ua lej ntawm lub cev (saib lossis qhov tseeb) uas tau khaws cia lossis tseem tsis hloov pauv hauv qee qhov kev hloov pauv.
Peb kawm dab tsi los ntawm symmetry?
Vim tib neeg lub cev muaj "kev xav symmetry , "Spotting pab tus neeg seev cev kom nws sib npaug. Los ntawm lub cev thiab kev xav ntawm kev seev cev, menyuam yaus kawm kom pom cov qauv thiab sim lawv qhov kev nkag siab. Qhov no ua haujlwm nrog cov qauv lej ib yam. Ntau tus menyuam yaus ntseeg tias qhov sib npaug txhais tau tias "cov lus teb."

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Lub luag haujlwm ntawm carbon nyob rau hauv molecular ntau haiv neeg ntawm lub neej yog dab tsi?
Cov pa roj carbon monoxide yog qhov tsis sib xws hauv nws lub peev xwm los tsim cov loj, complex, thiab ntau hom molecules. Cov proteins, DNA, carbohydrates, thiab lwm yam molecules uas paub qhov txawv ntawm cov khoom muaj sia los ntawm cov khoom siv tsis muaj sia yog txhua tus muaj cov pa roj carbon atoms sib txuas rau ib leeg thiab rau cov atoms ntawm lwm cov khoom
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
