Cov rod - cov qauv zoo li hauv lub cell nucleus uas muaj cov noob hu ua chromosomes.
Khaws qhov no hauv kev xav, dab tsi yog qhov puag ncig lossis pas nrig zoo li cov qauv hauv cytoplasm hu ua?
Lub luag haujlwm ntawm cov qauv tsim cov hlwb
| Cell qauv | Kev piav qhia |
|---|---|
| Mitochondria | Qws-zoo li cov qauv pom nyob rau hauv cytoplasm |
| Chloroplasts | Disc-shaped structures pom nyob rau hauv cytoplasm |
| Vacuole | Muab tso rau hauv cell uas muaj ntsev thiab suab thaj (cell sap) |
| Ribosomes | Me complexes pom nyob rau hauv cytoplasm |
Ib sab saum toj no, dab tsi yog lub hnab ntim hauv lub xov tooj ntawm tes uas ua raws li qhov chaw cia khoom? vacuole
Tsuas yog li ntawd, dab tsi muab lub cell zoo thiab kev txhawb nqa?
Lub cytoskeleton ntawm a cell yog tsim los ntawm microtubules, actin filaments, thiab intermediate filaments. Cov qauv no muab cov cell nws puab thiab pab teeb tsa cell cov ntu. Tsis tas li ntawd, lawv muab lub hauv paus rau kev txav mus los thiab cell kev faib.
Dab tsi khw muag khoom thiab tso tawm tshuaj nyob rau hauv ib lub cell?
Golgi Lub cev yog organelles uas pinch tawm ntawm endoplasmic reticulum, thiab khw muag khoom, tso tawm thiab thauj cov tshuaj.

Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Cov pas nrig twg yog siv hauv vuam?
Lub vuam electrode, uas feem ntau hu ua "welding qws," yog ib qho ntawm cov hlau nplaum uas muaj cov hlau nplaum uas tseem ua cov khoom siv thaum siv hauv cov txheej txheem vuam hu ua "shielded hlau arc vuam" lossis SMAW
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
Carbon pas nrig yog dab tsi?
Ultra high purity carbon rods yog siv rau carbon evaporation hauv EM daim ntaub ntawv. Cov qauv ntawm cov pa roj carbon monoxide yog nyob rau hauv qhov tseeb siab purity graphite uas yog tsim thaum lub sij hawm purification txheej txheem ntawm therods
