A ntsug hloov yog thaum daim duab qhia txav mus ntsug , nce los yog nqis. Qhov kev txav yog txhua yam raws li qhov tshwm sim rau y-tus nqi ntawm daim duab. Lub y-axis ntawm lub dav hlau coordinate yog qhov ntsug axis. Thaum muaj nuj nqi hloov vertically , y-tus nqi hloov.
Yog li ntawd, ua li cas koj thiaj nrhiav tau qhov kev hloov ntsug?
B pab koj xam lub sijhawm ntawm kev ua haujlwm. Yog tias koj faib tus C los ntawm B (C / B), koj yuav tau koj phase ua haujlwm . D yog koj li ntsug hloov . Cov ntsug hloov ntawm ib qho kev ua haujlwm trig yog tus nqi los ntawm qhov kev ua haujlwm trig yog transposed raws y-axis, lossis, hauv cov ntsiab lus yooj yim, tus nqi nws yog ua haujlwm nce lossis nqis.
Tsis tas li ntawd, koj ua li cas hloov txoj haujlwm sab laug thiab sab xis? Tsiv sab laug thiab sab xis Qhov no yeej ib txwm muaj tseeb: To ua haujlwm a muaj nuj nqi sab laug , ntxiv rau hauv lub muaj nuj nqi sib cav: f (x + b) muab f (x) ua haujlwm b mus units sab laug . Hloov chaw mus rau txoj cai ua haujlwm tib yam; f (x – b) yog f (x) ua haujlwm b mus units txoj cai.
Kuj paub yog, dab tsi yog qhov ntsug stretch?
A ntsug stretching yog cov ncab ntawm daim duab deb ntawm x-axis. A ntsug compression (los yog shrinking) yog qhov nyem ntawm daim duab mus rau x-axis.
Puas yog amplitude ib txwm zoo?
Cov amplitude lub ncov amplitude ntawm nthwv dej los yog kev vibration yog ib qho kev ntsuas ntawm kev sib txawv ntawm nws qhov tseem ceeb. Amplitudes yog ib txwm zoo tus lej (piv txwv li: 3.5, 1, 120) thiab yeej tsis muaj qhov tsis zoo (piv txwv li: -3.5, -1, -120).

Dab tsi yog qhov kev hloov pauv hloov pauv?
Kev hloov pauv, hauv molecular biology, yog hais txog kev hloov pauv hauv deoxyribonucleic acid (DNA), qhov twg ib qho (ob lub nplhaib) purine hloov pauv rau (ib lub nplhaib) pyrimidine, los yog vice versa
Vim li cas tom qab kev hloov pauv kev hloov pauv tseem ceeb?
Kev hloov pauv tom qab kev txhais lus (PTMs) xws li glycosylation thiab phosphorylation ua lub luag haujlwm tseem ceeb ntawm kev ua haujlwm ntawm hemostatic proteins thiab tseem ceeb heev hauv kev teeb tsa kab mob. Xws li theem nrab hloov pauv rau cov proteins hemostatic muaj ntau yam cuam tshuam rau lawv lub peev xwm los cuam tshuam nrog lwm cov proteins
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
Peb qhov laj thawj tseem ceeb ntawm kev hloov pauv hloov pauv yog dab tsi?
Allele frequencies nyob rau hauv ib tug pej xeem yuav hloov vim plaub lub hauv paus zog ntawm evolution: Natural Selection, Genetic Drift, Mutations thiab Gene Flow. Kev hloov pauv yog qhov kawg ntawm cov alleles tshiab hauv cov noob caj noob ces. Ob ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm kev hloov pauv hloov pauv yog: Natural Selection thiab Genetic Drift
