Hluav taws xob. Thaum lub suab tawm ntawm lub xov tooj cua , yog hloov los ntawm hluav taws xob zog rau ob leeg zog thiab mechanical zog . Suab zog yog mechanical zog vim lub vibratingmolecules tsim lub suab. Txhawm rau kom tau txais kev mloog xov tooj cua , koj yuav tsum ntsaws txoj hlua mus rau hauv qhov chaw.
Tsis tas li ntawd, lub zog hloov pauv dab tsi tshwm sim thaum lub tso suab tsheb qhib?
Teb: Zog tsis ploj, lub zog yog hloov los ntawm ib daim ntawv mus rau lwm daim ntawv. Thaum a tsheb lub tso suab yog qhib , cov xov tooj cua tsheb hloov xov tooj cua waves rau hluav taws xob zog , tom ntej no theelectrical zog hauv hloov suab nrov.
Ib tug kuj yuav nug, hom kev hloov pauv hluav taws xob twg tshwm sim thaum lub teeb hluav taws xob qhib? A. Muaj peev xwm zog hloov mus rau kinetic zog . B. Hluav taws xob zog yog hloov hauv tshav kub thiab lub teeb zog . C. Mechanical zog hloov mus rau hauv kinetic zog.
Yog li ntawd, lub zog hloov pauv hauv xov tooj cua yog dab tsi?
Zog yog pauv los ntawm rog / suab / hluav taws xob rau lub xov tooj cua . Ces zog yog pauv los ntawm xov tooj cua raws li tshuaj / suab thiab alsoby cua sov rau hloov thermal / kinetic zog rau xov tooj cua thiab ib puag ncig. Lus qhia Zog khw thiab hloov tsheb tuaj yeem pom hauv daim duab.
Dab tsi ntawm lub zog yog xov tooj cua?
Lub electromagnetic (EM) spectrum yog qhov ntau ntawm txhua tus hom ntawm EM hluav taws xob. Radiation yog zog uas taug kev thiab nthuav tawm thaum nws mus - lub teeb pom kev uas tuaj ntawm lub teeb hauv koj lub tsev thiab lub xov tooj cua nthwv dej uas los ntawm a xov tooj cua chaw nres tsheb yog ob hom ntawm electromagnetic tawg.

Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
Dab tsi tshwm sim rau qhov kub ntawm cov khoom thaum lub sij hawm hloov pauv?
Thaum lub sijhawm hloov pauv, qhov kub ntawm ib yam khoom tseem nyob tas li. Peb feem ntau saib cov theem hloov ntawm cov khoom mus rau cov kua, xws li cov dej khov yaj. Qhov no yog vim hais tias cov cua sov uas tau muab rau cov dej khov molecules yog siv los ua kom lawv lub zog kinetic, uas yog tshwm sim hauv qhov kub thiab txias
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Lub zog siv hluav taws xob txuag tau li cas thaum hloov pauv lossis hloov pauv?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias rau txhua qhov system, lub zog tsis tuaj yeem tsim lossis rhuav tshem; nws tsuas tuaj yeem hloov ntawm ib daim ntawv mus rau lwm qhov lossis hloov ntawm ib yam khoom mus rau lwm qhov. Mechanical zog los ntawm ob hom: lub zog muaj peev xwm, uas yog khaws cia lub zog, thiab lub zog kinetic, uas yog lub zog ntawm kev txav
