Ntau pua xyoo dhau los, Ireland tau ntsib kev puas tsuaj tag nrho ntawm nws cov hav zoov feem ntau yog vim tib neeg kev ua haujlwm thiab kev nyab xeeb ntawm huab cua: los ntawm thawj zaug hav zoov npog thaj tsam ntawm 80% mus rau tsawg dua 1%.
Lub teb chaws twg tsis muaj tsob ntoo?
Qatar - qhov tseeb suab puam Tab sis tu siab, qhov no opulent teb chaws tsis muaj tsob ntoo.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Lub ntsiab lus twg yog pom nyob rau hauv qhov tsuas yog nyob rau hauv tebchaw quizlet?
Halogens yeej ib txwm pom nyob rau hauv cov xwm txheej incompounds vim hais tias halogens yog heev reactivenonmetals
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
Yuav ua li cas yog ib co qauv nyob rau hauv landforms nyob rau hauv lub ntiaj teb no?
Cov txheej txheem ntawm lub cev no ua rau cov roob, tiaj, toj, thiab toj siab, plaub hom av loj. Phaj tectonics tuaj yeem tsim cov roob thiab toj roob hauv pes thaum yaig tuaj yeem hnav cov av los tsim cov hav thiab hav zoov
