A tswj kab sib chaws muaj ob txoj kab perpendicular, los yog axes, sau npe zoo li cov kab zauv. Kab rov tav axis hu ua x-axis. Lub axis ntsug yog hu ua y-axis. Lub ntsiab lus uas lub x-axis thiab y-axis sib tshuam yog hu ua lub hauv paus. Cov lej ntawm a tswj kab sib chaws yog siv los nrhiav cov ntsiab lus.
Ntawm no, dab tsi yog quadrants ntawm ib daim phiaj sib koom tes?
Cov axes ntawm ob-dimensional Cartesian system faib cov dav hlau mus rau plaub lub cheeb tsam infinite, hu ua quadrants , txhua bounded los ntawm ob ib nrab-axes. Cov no feem ntau suav los ntawm 1st mus rau 4th thiab qhia los ntawm Roman tus lej: Kuv (qhov twg cov cim ntawm (x; y) ua haujlwm I (+;+), II (−;+), III (−;-), and IV (+;-).
Ib tug kuj yuav nug, dab tsi yog qhov piv txwv ntawm lub dav hlau sib koom tes? A tswj lub dav hlau muaj ob tug xov tooj uas sib tshuam, ib tug khiav horizontally, lwm yam khiav vertically. Kab rov tav tus lej ntawm a tswj lub dav hlau yog lub npe hu ua x-axis. Vertical number kab ntawm a tswj lub dav hlau yog lub npe hu ua y-axis.
Ntxiv mus, dab tsi yog qhov coordinates ntawm ib daim duab?
Ib khub xaj (x, y) sawv cev rau txoj haujlwm ntawm ib qho taw tes ntawm a ua hauj lwm graph , qhov twg x yog tus lej ntawm x-axis uas cov ntsiab lus txuas nrog thiab y yog tus lej ntawm y-axis uas cov ntsiab lus txuas nrog. Cov lej x thiab y nyob rau hauv cov xaj xaj (x, y) raug hu ua haujlwm.
Puas yog Quadrant 1 zoo lossis tsis zoo?
Hauv Quadrant I, ob qho tib si x- thiab y-coordinates yog qhov zoo; hauv Quadrant II , x-coordinate yog qhov tsis zoo, tab sis y-coordinate yog qhov zoo; hauv Quadrant III ob leeg tsis zoo; thiab hauv Quadrant IV, x yog qhov zoo tab sis y yog qhov tsis zoo.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog Y coordinate?
Ib qho y-coordinate yog qhov thib ob hauv ib khub xaj. Thaum ib khub txiav txim tau kos duab raws li qhov kev sib koom ua ke ntawm qhov taw tes hauv lub dav hlau sib koom ua ke, y-coordinate sawv cev rau qhov kev ncua deb ntawm qhov taw tes ntawm x-axis. Lwm lub npe rau y-coordinate yog tus ordinate
