Zoo nitrogen tshuav cuam tshuam nrog lub sijhawm ntawm kev loj hlob, hypothyroidism, kho cov ntaub so ntswg, thiab cev xeeb tub. Qhov no txhais tau hais tias kev noj cov nitrogen rau hauv lub cev ntau dua li qhov poob ntawm nitrogen los ntawm lub cev, yog li muaj kev nce hauv tag nrho lub cev lub pas dej ntawm cov protein.
Thaum twg nitrogen poob ntau dua cov nitrogen coj mus rau hauv lub cev?
Thaum nitrogen coj mus rau hauv lub cev ntau tshaj nitrogen losses, peb hais tias tus neeg nyob rau hauv: positive nitrogen balance.
Dab tsi ua rau qhov tsis zoo nitrogen tshuav?
Ib qho tsis zoo nitrogen tshuav yuav tshwm sim thaum lub cev lossis lub siab xav, kev tshaib plab, thaum tus neeg noj zaub mov tsis muaj calorie ntau, lossis thaum cov protein tsis zoo (piv txwv li. thaum noj zaub mov tsis muaj cov amino acids tseem ceeb).
Yuav ua li cas thaum lub cev tsis tuaj yeem khaws cov nitrogen ntau?
Vim tib neeg lub cev tsis tuaj yeem khaws cov nitrogen ntau dhau, ammonia yog tsim los ntawm cov nitrogen ntau dhau thiab lub siab hloov mus rau hauv urea, uas thaum kawg tshem tawm los ntawm lub raum. ammonia yog tsim los ntawm cov nitrogen ntau dhau thiab lub siab hloov nws mus rau hauv urea, uas thaum kawg tshem tawm los ntawm ob lub raum.
Puas yog qhov tso tawm ntawm nitrogen ntau tshaj qhov kev siv nitrogen Cov mob hu ua?
Ib qho zoo NB lossis lub xeev anabolic tshwm sim thaum noj nitrogen ntau tshaj cov khoom tso tawm nitrogen. Net 24-teev zoo NB ntawm 2 rau 4g yogzoo rau anabolism. Thaum muaj nitrogen excretion ntau dua nitrogen kom tsawg, muaj negative NB lossis catabolic xeev tshwm sim.

Puas yog n95 lub qhov ncauj qhov ntswg nrog lub qhov nqus pa muaj kev nyab xeeb?
Puas yog nws hnav N95 lub ntsej muag lub ntsej muag nrog lub qhov nqus pa los tiv thaiv kuv thiab lwm tus los ntawm COVID-19? Yog, N95 lim lub ntsej muag lub ntsej muag yuav tiv thaiv koj thiab muab kev tswj hwm los tiv thaiv lwm tus. NIOSH-pom zoo N95 filtering facepiece respirator nrog lub exhalation valve muaj kev tiv thaiv tib yam rau tus neeg hnav li ib qho uas tsis muaj lub valve.
Qhov twg halide ntawm nitrogen yog qhov tsawg tshaj plaws?
Fluorine yog cov electronegative tshaj plaws rub cov electron ceev ntawm nws thiab yog li nws nyuaj rau nitrogen atom pub dawb rau ib leeg ntawm electron. Down pab pawg raws li electronegativity txo qhov pib nce. Yog li, NF3 yog qhov tsawg kawg nkaus nitrogen trihalide.
Thaum lub cev qhuav dej lub cev yuav nce ntau lawm?
Lub cev qhuav dej lossis kev ntxhov siab ntawm lub cev tuaj yeem ua rau nce osmolaritysiab dua 300 mOsm / L, uas dhau los, nce ADH secretion thiab dej yuav khaws cia, ua rau nce ntshav siab.. ADH taug kev hauv cov hlab ntsha mus rau lub raum.
Thaum twg qhov kub ntawm qhov siab tshaj plaws thiab qis tshaj?
Qhov kub tshaj plaws uas tau sau tseg hauv ntiaj teb yog 136 Fahrenheit (58 Celsius) hauv Libyan suab puam. Qhov ntsuas kub tshaj plaws uas tau ntsuas yog -126 Fahrenheit (-88 Celsius) ntawm Vostok Chaw Nres Tsheb hauv Antarctica. Thaum twg qhov kub ntawm qhov qis tshaj?
Dab tsi yog qhov nqus nqus tampon qis tshaj?
Nov yog lo lus nug zoo. Yog tias koj cev xeeb tub thawj zaug, nws yuav yog qhov zoo tshaj plaws los siv cov tampon qis tshaj plaws (feem ntau sau tias yog nyias, lub teeb, lossis junior). Cov qhov loj me no feem ntau nyiam dua thiab tuaj yeem nkag tau yooj yim dua rau cov neeg tshiab rau cov txheej txheem.
