DNA , uas sawv cev rau deoxyribonucleic acid, txhais tau tias yog ib qho nucleic acid uas muaj cov cai caj ces.
Ntxiv rau qhov no, DNA sawv cev rau cov lus teb li cas?
DNA . Koj DNA yog dab tsi ua rau koj uniquely koj. DNA sawv rau deoxyribonucleic acid, qee zaum hu ua "lub molecule ntawm lub neej," raws li yuav luag tag nrho cov kab mob muaj lawv cov genetic khoom codified li. DNA.
Tsis tas li ntawd, lo lus kho mob DNA yog dab tsi? Kho mob Kev txhais ntawm DNA DNA Tom ntej: Deoxyribonucleic acid. Ib ntawm ob hom molecules uas encode cov ntaub ntawv caj ces. (Lwm yam yog RNA. Hauv tib neeg DNA yog cov khoom siv caj ces; RNA tau sau los ntawm nws. Hauv qee lwm yam kab mob, RNA yog cov khoom siv caj ces thiab, nyob rau hauv kev hloov pauv, tus DNA tau sau los ntawm nws.)
Tsuas yog li ntawd, tag nrho lub ntsiab lus ntawm DNA thiab RNA yog dab tsi?
DNA stands rau deoxyribonucleic acid, thaum RNA yog ribonucleic acid. Txawm tias DNA thiab RNA ob leeg nqa cov ntaub ntawv genetic, muaj ob peb qhov sib txawv ntawm lawv.
DNA ua los ntawm dab tsi?
DNA qauv DNA yog ua los ntawm molecules hu ua nucleotides. Txhua nucleotide muaj ib pawg phosphate, pawg suab thaj thiab nitrogen hauv paus. Plaub hom nitrogen hauv paus yog adenine (A), thymine (T), guanine (G) thiab cytosine (C). Qhov kev txiav txim ntawm cov hauv paus no yog qhov txiav txim siab DNA cov cov lus qhia, los yog genetic code.

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Lub ntiaj teb yuav hloov li cas yog tias cov nyhuv tsev cog khoom tsis muaj nyob rau hauv tag nrho cov lus nug?
A) Yog tsis muaj cov nyhuv tsev cog khoom, lub ntiaj teb yuav tawg tag nrho nws cov cua sov rau hauv qhov chaw. b) Txhua lub hnub ci hluav taws xob tuaj yeem nqus tau yam tsis muaj lub tsev cog khoom. C) Qhov tshwm sim ntawm tsis muaj cov nyhuv tsev cog khoom yuav yog lub ntiaj teb kub heev uas yeej tsis txias
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Dab tsi Circuit Court voltage yog tib yam nyob rau hauv tag nrho cov ceg?
Nyob rau hauv ib qho kev sib txuas, qhov voltage dropsacross txhua ntawm cov ceg yog tib yam li qhov hluav taws xob nce hauv lub roj teeb. Yog li, qhov voltagedrop yog tib yam nyob rau txhua tus ntawm cov resistors
Ntau npaum li cas ntawm cov pej xeem hauv ntiaj teb nyob ntawm cov kab ke roob rau tag nrho lossis qee qhov ntawm lawv cov dej?
Roob yog lub ntiaj teb "dej yees," muab 60-80% ntawm tag nrho cov dej tshiab rau peb ntiaj chaw. Tsawg kawg ib nrab ntawm lub ntiaj teb cov pej xeem nyob ntawm roob ecosystem kev pabcuam kom muaj sia nyob - tsis yog dej xwb, tab sis kuj muaj zaub mov thiab lub zog huv
