Ntshav . Tib neeg ntshav muaj a tsis pub carbonic acid (H 2CO 3thiab bicarbonate anion (HCO 3 -) kom tswj tau ntshav pH ntawm 7.35 thiab 7.45, raws li tus nqi siab dua 7.8 lossis qis dua 6.8 tuaj yeem ua rau tuag taus.
Ntawm no, dab tsi yog cov kab mob ntawm cov ntshav?
Cov tsis system ua haujlwm hauv ntshav plasma muaj xws li plasma proteins, phosphate, thiab bicarbonate thiab carbonic acid buffers . Lub raum pab tswj cov kua qaub-puag tshuav los ntawm kev tso tawm hydrogen ions thiab tsim bicarbonate uas pab tswj ntshav plasma pH nyob rau hauv ib txwm muaj.
Ib sab saum toj no, dab tsi yog qhov tsis zoo tshaj plaws hauv lub cev? Bicarbonate tsis pub yog cov feem ntau tseem ceeb tsis system hauv ntshav plasma (feem ntau nyob rau hauv cov kua dej extracellular).
Ib yam li ntawd, peb lub tshuab tsis tseem ceeb hauv tib neeg lub cev yog dab tsi?
1 Teb. Cov peb lub cev tsis zoo ntawm peb lub cev yog carbonic acid bicarbonate tsis system , phosphate tsis system thiab protein tsis system.
Lub luag haujlwm tseem ceeb ntawm phosphate tsis yog dab tsi?
Txawm tias cov phosphate buffer system tsis yog ib qho tseem ceeb-tant li cov kua dej extracellular tsis pub , ua play a lub luag haujlwm tseem ceeb hauv tsis kam lub raum tubular kua thiab intracellular kua. Thaum lub hauv paus muaj zog, xws li NaOH, ntxiv rau lub tsis system , ua OH– yog buffed los ntawm H2PO4– los tsim cov HPO ntxiv4= + H2O.

Dab tsi yog 4 yam tseem ceeb tshaj plaws hauv cov kab mob muaj sia?
Raws li koj tuaj yeem pom hauv daim duab duab ntawm sab laug, kwv yees li 97 feem pua ntawm koj lub cev hnyav tsuas yog muaj plaub yam tseem ceeb - oxygen, carbon, hydrogen, thiab nitrogen. Rau feem ntau cov khoom nyob rau hauv lub neej yog carbon, hydrogen, oxygen, nitrogen, phosphorus, thiab sulfur
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Dab tsi yog qhov txawv ntawm cov khoom tseem ceeb thiab cov kab hauv cov dej hiav txwv?
Ib cag ntawm 12 lub ntsiab lus uas yog cov ntsiab lus tseem ceeb lossis cov ntsiab lus me thiab qee cov ntsiab lus uas yog cov roj yaj, tag nrho lwm cov ntsiab lus yaj hauv dej hiav txwv muaj nyob rau hauv cov ntsiab lus tsawg dua 1 ppm thiab hu ua cov kab hauv qab. Ntau cov kab ke tseem ceeb rau lub neej
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
