Atoms yog ib txwm ua los ntawm cov khoom . Atoms yog qee zaum ua los ntawm cov khoom . Lawv txhua tus muaj ob tsab ntawv hauv lawv cov cim atomic. Cov muaj pes tsawg leeg.
Ua li no, cov ntsiab lus yog ua los ntawm atoms?
Ib cov ntsiab lus yog ib yam khoom uas yog ua tawm ntawm atoms uas txhua tus muaj tib tus lej proton. Yog li ib keeb tuaj yeem muaj ntau yam atoms (zoo li oxygen uas mus ncig ua khub). Ib atom muaj ib tug nucleus thiab ib co electrons.
Tom qab, lo lus nug yog, puas tuaj yeem tsim cov atoms? 2. Atoms ua tsis tau tsim tsis raug puas tsuaj, thiab lawv yog indestructible; lawv tsis tuaj yeem tawg ua qhov me me. Qhov no yog ua raws li Txoj Cai Tswjfwm Ntiag Tug, nws tau kawm tom qab ntawd atoms tau tawg rau hauv qhov me me.
Hais txog qhov no, puas muaj dab tsi tsis ua los ntawm atom?
Neutron hnub qub yog ua tawm ntawm neutrons, yog li muaj yeej tsis muaj atoms nyob ntawd . Cov teeb meem me me uas nyob nruab nrab ntawm cov hnub qub lossis nruab nrab ntawm galaxies, uas yog feem ntau ntawm cov huab hwm coj hauv ntiaj teb (!) ( tsis yog suav nrog cov teeb meem tsaus ntuj), kuj yog tsis yog feem ntau ua los ntawm atoms . Nws yog qhov tseeb tias plasma zoo li sib xyaw ntawm protons thiab electrons.
Puas yog atoms ciaj sia?
Atoms tsis yog ciaj sia . Txhua yam tsis yog ua los ntawm atoms , txhua yam ua los ntawm atoms yog ua los ntawm atoms . Lawv siv tib yam atoms raws li tsis muaj sia nyob yog li koj yuav tsis pom cov lus teb los ntawm kev ntsia ntawm atoms . Tab sis koj yuav kawm txog chemistry uas yog raws li qhov tseeb tias tsis yog txhua tus atoms yog tib yam, los yog coj tus kheej.

Puas yog 5 tus lej cov ntsiab lus suav nrog cov ntawv tshaj tawm?
Tsib Naj Npawb Summary yog ib txoj hauv kev los sau cov ntaub ntawv faib tawm. Tsib tus lej yog qhov tsawg kawg nkaus, thawj quartile (Q1) tus nqi, qhov nruab nrab, qhov thib peb quartile (Q3) tus nqi, thiab qhov siab tshaj plaws. Qhov no txawv heev ntawm cov ntaub ntawv ntxiv. Nws yog ib qho outlier thiab yuav tsum tau muab tshem tawm
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
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
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
