Iintsholongwane zizinto ezincinci kakhulu ezosulelayo ezinokuzala kuphela ngaphakathi kwiiseli eziphilayo. Zinokubangela iintlobo ngeentlobo zezifo ebantwini, kwizilwanyana nakwizityalo. Iintsholongwane zinokusasazeka ngeendlela ezahlukeneyo, kubandakanya ukudibana ngqo, umoya, amanzi, ukutya, kunye neentsholongwane ezifana nezinambuzane. Ngenxa yeengozi ezinokubakho ngenxa yosulelo lweentsholongwane, ukuthintela ukusasazeka… Funda ngokugqithisileyo
Iintsholongwane zizinto ezincinci ezosulelayo ezinokuphindaphindeka kuphela kwiiseli eziphilayo. Ziyaziwa ngokubanga iintlobo ngeentlobo zezifo ezinzulu ebantwini, kwizilwanyana nakwizityalo. Nangona kunjalo, indima yeentsholongwane idlulela ngaphaya kwezi nkalo zimbi. Kwiimeko ezininzi, iintsholongwane zikwadlala indima ebalulekileyo kwiinkqubo zendalo, uphando lwesayensi, kunye ne-biotechnology. Eli nqaku… Funda ngokugqithisileyo
Iintsholongwane ziintsholongwane ezibangela usulelo ezincinci ezinokuzala ngaphakathi kwiiseli eziphilayo kuphela. Ukuzala kweentsholongwane kwahlukile nje kuphela kwindlela ezinye izinto eziphilayo ezizala ngayo, kodwa kuxhomekeke kakhulu kuhlobo lwentsholongwane kunye nomsingathi abamsulelayo. Eli nqaku liza kuchaza indlela iintsholongwane ezizala ngayo, ligubungela amanqanaba aphambili omjikelo wobomi bentsholongwane, umahluko kwi… Funda ngokugqithisileyo
Iintsholongwane ziintsholongwane ezibangela usulelo ezincinci ezinokuzala ngaphakathi kwiiseli eziphilayo kuphela. Zizinto ezizodwa, ezahlukileyo kwezinye izinto eziphilayo, kuba azinaso isakhiwo seseli okanye imetabolism yazo kwaye zixhomekeke ngokupheleleyo kumninimzi ukuze ziphindaphindeke. Ukuqonda iintsholongwane kubandakanya ulwazi ngesakhiwo sazo, iintlobo zazo, imijikelo yobomi, kunye nempembelelo kwizinto eziphilayo… Funda ngokugqithisileyo
Iintsholongwane ziiarhente ezibangela usulelo ezincinci ezinokuzala kuphela ngaphakathi kwiiseli zezinto eziphilayo. Iintsholongwane zibonwa njengenxalenye ebalulekileyo yendalo yoMhlaba, zinendima ezahlukeneyo, ukusuka kwiiarhente ezibangela izifo ukuya kwizixhobo zophando lwesayensi kunye ne-biotechnology. Inkcazo kunye neempawu zeentsholongwane Ngokwesakhiwo, iintsholongwane ziquka i-nucleic acid (DNA… Funda ngokugqithisileyo
Ifomula ye-Angular Momentum Intshayelelo I-Angular momentum yingcamango ebalulekileyo kwifiziksi enxulumene nentshukumo yokujikeleza kwento. Ifana ne-linear momentum kwintshukumo yoguqulelo. I-Angular momentum idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zefiziksi, ukusuka kwi-classical mechanics ukuya kwi-quantum mechanics. Eli nqaku liza kuxoxa ngenkcazo ye-angular momentum, iifomyula ezinxulumene nayo, kunye nokusetyenziswa kwayo kwi... Funda ngokugqithisileyo
Ifomula Yombane Intshayelelo Yombane Amandla ombane yingcamango esisiseko kwifiziksi yombane echaza amandla ombane anokubakho ngeyunithi nganye yokutshaja kwindawo ethile kwintsimi yombane.
