Viruses muaj capsids, thiab Eukaryotes, xws li cov nroj tsuag thiab tsiaj txhu muaj daim nyias nyias. Qhov tseem ceeb zoo sib xws thiab kev ua haujlwm ntawm ob lub capsid thiab ib daim nyias nyias yog los muab kev tiv thaiv.
Dab tsi yog capsids thiab nuclear membranes?
A capsid yog protein "lub tsho" uas tsim lub cev ntawm tus kab mob. Lub luag haujlwm tseem ceeb ntawm daim nyias nyias yog kom muaj thiab tiv thaiv cov caj ces ntawm lub cell: nws DNA.
Yuav ua li cas yog lub nuclear membrane zoo ib yam li?
Ntxiv rau, cov txheej txheem sab nraud ntawm cov ntaub so ntswg ua haujlwm zoo ib yam li cov membranes ntawm endoplasmic reticulum(saib Tshooj 9) thiab muaj ribosomes khi rau nws cytoplasmic nto. Nyob rau hauv sib piv, lub hauv paus nuclear membrane nqa cov proteins uas tshwj xeeb rau lub nucleus.
Dab tsi yog lub luag haujlwm ntawm capsids?
Ib lub luag haujlwm tseem ceeb ntawm capsid yog txhawm rau tiv thaiv kab mob genome los ntawm ib puag ncig thiab thaum kawg xa cov genome mus rau sab hauv ntawm homologous host cell.
Dab tsi yog lwm txoj haujlwm ntawm cov khoom siv nuclear?
Ib daim nyias nyias nyias yog ob daim nyias nyias uas ntim cov cell nucleus. Nws ua haujlwm cais cov chromosomes los ntawm qhov seem ntawm lub xovtooj Cov ntaub so ntswg nuclear suav nrog cov qhov me me lossis qhov pores uas tso cai rau kev nkag mus ntawm qee cov ntaub ntawv, xws li nucleic acids thiab proteins, ntawm qhov nucleus thiab cytoplasm.

Qhov txawv ntawm kev sib raug zoo thiab kev ua haujlwm yog dab tsi?
Qhov txawv ntawm qhov kev sib raug zoo thiab kev ua haujlwm yog kev sib raug zoo tuaj yeem muaj ntau qhov tawm rau ib qho kev tawm tswv yim, tab sis ib qho kev ua haujlwm muaj ib qho kev tawm tswv yim rau ib qho tawm. Qhov no yog qhov tseem ceeb tshaj plaws los sib txawv ntawm kev sib raug zoo thiab kev ua haujlwm.
Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Yuav ua li cas ua cov feem tsis sib xws rau feem zoo sib xws?
Mua ob ntu ntawm txhua feem los ntawm tus lej ntawm lwm feem, yog tias tus lej sib txawv. Piv txwv li, yog tias koj ntxiv 1/3 thiab 2/5, muab ob qho tib si 1 thiab 3 los ntawm 5, ua cov feem 5/15. Tom qab ntawd muab ob qho tib si 2 thiab 5 los ntawm 3 (tus denominator ntawm lwm feem), ua tus feem 6/15 .
Dab tsi yog qhov kev sib raug zoo ntawm qhov tsis meej thiab cov ntsiab lus txhais?
tsis meej pem thiab txhais cov kev xav tau muaj feem cuam tshuam rau qhov lawv ob leeg qhia ntau txoj hauv kev rau ib lo lus lossis kab lus, es tsis muaj lus teb. Txhawm rau kom nkag siab qhov tseem ceeb ntawm ib lo lus lossis kab lus, yuav tsum muaj cov khoom tshwj xeeb uas tshem tawm txoj hauv kev rau qhov tsis meej .
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
