Cov hlwb uas tsim cov kab mob no muaj ib txoj hauj lwm loj - ua kom cov kab mob no noj qab nyob zoo kom lawv loj hlob thiab yug me nyuam. Kev saib xyuas ntawm ruaj khov , tas li , cov xwm txheej sab hauv hu ua homeostasis. Koj cell ua qhov no los ntawm regulating lawv sab hauv ib puag ncig kom lawv txawv ntawm ib puag ncig sab nraud.
Ib sab ntawm qhov no, cov cell membrane ua li cas tswj kev ruaj ntseg sab hauv?
Cov cell membrane Nws yog ib qho lipid bilayer uas tiv thaiv qhov kev nkag ntawm dej thiab ions. Qhov no tso cai hlwb rau tswj ib tug ntau dua concentration ntawm sodium ions tawm sab nraum lub cell . Cells kuj tswj ib tug ntau dua concentration ntawm potassium ions thiab organic acids ntawm lawv sab hauv.
Ib tug kuj yuav nug, puas yog tswj kev ruaj ntseg hauv lub cev? Homeostasis yog hais txog lub cev lub cev ua haujlwm rau tswj kev ruaj ntseg ntawm lub cev thiab ntawm nws qhov chaw ib puag ncig. Yooj yim muab tso, homeostasis feem ntau cuam tshuam nrog tag nrho cov txheej txheem ntawm kev tswj hwm thiab kev saib xyuas hauv lub cev kom muaj kev sib npaug ntawm lub cev ua haujlwm.
Ib yam li ntawd, cov hlwb yuav tsum ua dab tsi los tswj homeostasis?
Txhawm rau txhim kho homeostasis:
- Cell yuav tsum muaj peev xwm tau txais lub zog feem ntau los ntawm mitochondria hauv daim ntawv ntawm ATP.
- Cell muaj peev xwm ua kom cov hlwb tshiab.
- Muaj peev xwm pauv cov khoom siv.
- Thiab qhov kawg yog, tsis tu ncua tshem tawm cov khib nyiab.
Vim li cas cov kab mob muaj sia nyob yuav tsum muaj qhov kub thiab txias tsis tu ncua?
Tej Yam Uas Yuav Tsum Muaj Kev Ruaj Ntseg Hauv Sab Hauv Ib puag ncig hws pab ua kom peb txias. Thaum hws evaporates ntawm daim tawv nqaij, nws siv qee lub zog ntawm lub cev kub. Nws pab kom lub cev internal kub tsis tu ncua . Thaum lub cev sab hauv ib puag ncig yog ruaj khov , tus mob hu ua homeostasis.

Dab tsi yog kev saib xyuas ntawm kev ruaj ntseg sab hauv txawm tias muaj kev hloov pauv hauv ib puag ncig sab nraud?
Kev saib xyuas ntawm kev ruaj ntseg sab hauv txawm tias muaj kev hloov pauv hauv ib puag ncig sab nraud yog hu ua homeostasis
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Vim li cas kev sib txhuam quab yuam tsis yog kev ruaj ntseg?
Lub zog yog hais tias tsis yog-conservative thaum ua hauj lwm tawm tsam nws tsis tseg los ntawm lub cev uas yog txav los ntawm lub zog. Ib qho piv txwv zoo ntawm hom kev quab yuam tsis yog kev sib txhuam. Thaum lub cev txav tawm tsam kev sib txhuam, kev ua haujlwm yuav tsum tau kov yeej kev sib txhuam. Kev ua haujlwm yog lub zog thiab yog li nws tsis tuaj yeem poob
Vim li cas nws tseem ceeb uas yuav tsum rov ua qhov kev sim thiab sim cov kev xav hauv ntau txoj kev?
Nws yog ib qho tseem ceeb rau cov kws tshawb fawb kom rov sim dua thaum ua qhov kev sim vim tias qhov kev txiav txim siab yuav tsum raug lees paub. Muaj tseeb vim tias cov txiaj ntsig ntawm txhua qhov kev xeem yuav tsum zoo sib xws. Lwm cov kws tshawb fawb yuav tsum tuaj yeem rov ua koj qhov kev sim thiab tau txais cov txiaj ntsig zoo sib xws. Tib txoj hauv kev los ntsuas qhov kev xav yog ua qhov kev sim
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
