Daim video no muaj tag nrho cov yuav tsum tau siv rau Daim ntawv Biology 1 suav nrog microscopes, osmosis, enzymes, kuaj zaub mov thiab photosynthesis rau cov tub ntxhais kawm ua ke thiab a xav tau tswv yim rau cais cov menyuam kawm ntawv txog kev ua tau zoo ntawm cov tshuaj tua kab mob ntawm kev kho cov kab mob.
Ib yam li ntawd ib tug yuav nug, muaj pes tsawg lub tswv yim yuav tsum muaj nyob rau hauv biology?
AQA 9-1 Biology Required Summary Revision. Ib lub ntsiab lus ntawm txhua tus 10 qhov yuav tsum tau ua rau cov tub ntxhais kawm theem nrab-nrab muaj peev xwm kawm AQA biology GCSE. Muaj ob qho tseem ceeb thiab triple qhov yuav tsum tau ua thiab suav nrog cov yeeb yaj kiab pab tau los ntawm cov channel YouTube zoo!
Tsis tas li ntawd, vim li cas peb thiaj li xav tau cov tswv yim hauv biology? Biology yog a siv tau kev kawm. Siab zoo, tsim nyog biology kev sim thiab kev tshawb nrhiav yog tus yuam sij rau kev txhim kho kev kawm, thiab kev qhia meej thiab sib sau ua ke ntawm txoj kev xav. Tseem ceeb heev, siv tau ua hauj lwm ua rau cov tub ntxhais kawm nkag siab txog yuav ua li cas lom kev paub yog generated los ntawm kev sim thiab kev soj ntsuam.
Ua raws li qhov no hauv kev txiav txim siab, muaj pes tsawg qhov yuav tsum tau ua?
muaj 10 yam uas yuav tsum tau ua rau biology, suav nrog peb qhov kev qhia ntxiv uas xav tau rau qhov kev tsim nyog GCSE Biology ib leeg - cov tswv yim 2, 8 thiab 10 • muaj 8 yam uas yuav tsum tau ua rau chemistry, suav nrog ob qho kev qhia ntxiv uas xav tau rau tus kheej GCSE Chemistry kev tsim nyog -
Muaj pes tsawg qhov yuav tsum tau ua muaj rau kev sib koom ua ke?
Phau ntawv xeem tshiab no rau cov tub ntxhais kawm tom qab AQA GCSE Ua ke Science muab cov phiaj xwm kev xyaum tshwj xeeb rau 21 Yuav tsum tau xyaum . Cov lus teb muaj rau rub tawm los ntawm oxfordsecondary.co.uk/ xav tau - siv tau - teb.

Yuav ua li cas cov xwm txheej yuav tsum tau induce ib tug tam sim no nyob rau hauv ib lub voj ntawm hlau?
Hypothesis: Yuav kom induce ib tug tam sim no nyob rau hauv ib lub voj ntawm hlau, tej yam kev mob yuav tsum tau hais tias muaj ib tug magnetic teb. Qhov no yog vim hais tias thaum ib tug conductor txav los ntawm ib tug magnetic teb, ib tug induced tam sim no yog tsim
Dab tsi yuav tsum tau rau electrons txav mus rau hauv txoj kev muaj txiaj ntsig?
Lub zog yuav tsum tau pub dawb valence electrons yog hu ua band gap zog vim tias nws txaus los txav ib qho hluav taws xob los ntawm lub valence band los yog sab nrauv electron plhaub, mus rau hauv cov khoom siv hluav taws xob uas thaum lub electron txav mus los ntawm cov khoom siv thiab cuam tshuam cov atoms nyob sib ze
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
Yuav ua li cas yog rau cov ntaub ntawv nug uas yuav tsum tau kawm nyob rau hauv ib tug ua txhaum cai?
Qee yam ntawm cov ntaub ntawv nug uas raug kuaj xyuas cov ntaub ntawv pov thawj tau hais hauv qab no. • Xav. • Tshawb xyuas. • Cov Nyiaj Txiag Nyiaj Txiag. • Daim ntawv cog lus. • Cov ntawv txais nyiaj. • Tub Sab Nraud. • Kev dag ntxias. • Kev cuav. • Kev tua tus kheej. • Kev tua neeg. • Nto nta. • Cov duab latent. • Kev hloov pauv. • Watermarks. • Ink stamps
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
