Tag nrho nyob kab mob sib koom ntau yam tseem ceeb yam ntxwv los yog kev ua haujlwm: kev txiav txim, rhiab heev lossis kev teb rau ib puag ncig, kev tsim tawm, kev loj hlob thiab kev loj hlob, kev tswj hwm, homeostasis, thiab kev ua lub zog. Thaum saib ua ke, cov no yam ntxwv ua hauj lwm los txhais lub neej.
Tsis tas li ntawd, 7 yam ntxwv ntawm lub neej yog dab tsi?
Cov no yog xya yam ntxwv ntawm cov kab mob nyob
- 1 Khoom noj khoom haus. Cov khoom muaj sia nyob hauv cov khoom siv los ntawm lawv ib puag ncig uas lawv siv rau kev loj hlob lossis muab lub zog.
- 2 Ua pa.
- 3 Kev txav mus los.
- 4 Kev tso tawm.
- 5 Kev loj hlob.
- 6 Kev tsim tawm.
- 7 Kev xav.
Tsis tas li ntawd, 10 yam ntxwv ntawm lub neej yog dab tsi? 10 Yam ntxwv Ntawm Cov Kab Mob Nyob
- cellular muaj pes tsawg leeg. lub xovtooj ntawm tes suav hais tias yog chav tsev tseem ceeb ntawm lub neej raws li nws yog chav tsev me tshaj plaws uas tuaj yeem nqa nws tawm ntawm lub neej.
- metabolism. chemicals yog cov khoom uas muaj qhov tshwj xeeb molecular muaj pes tsawg leeg uas siv los yog tsim los ntawm cov txheej txheem tshuaj.
- kev loj hlob.
- tshem tawm.
- kev teb.
- kev txav mus los.
- kev yug me nyuam.
- kev loj hlob.
Ua li no, dab tsi yog yam ntxwv ntawm kev muaj sia nyob?
Cov yam ntxwv yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Ib txhia yam , xws li tus kab mob, ua kom pom tsuas yog qee qhov ntawm cov no yam ntxwv thiab yog li ntawd, tsis ciaj sia.
Dab tsi yog cov yam ntxwv ntawm kev ua neej thiab tsis muaj sia?
Yam Ntxim Saib Ntxim Ua Nyob Thiab Tsis Muaj Nyob
- Txhua yam uas muaj sia nyob ua pa, noj, loj hlob, txav mus los, tsim tawm thiab muaj kev nkag siab.
- Cov khoom uas tsis muaj sia tsis noj, loj hlob, ua pa, txav thiab rov tsim dua. Lawv tsis muaj kev xav.

Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Cov yam ntxwv dab tsi uas cov kws tshawb fawb siv los faib cov pob zeb?
Feem ntau cov zaub mov tuaj yeem ua tus cwj pwm thiab cais los ntawm lawv lub cev tshwj xeeb: hardness, luster, xim, strrea Feem ntau cov zaub mov tuaj yeem ua tus yam ntxwv thiab cais los ntawm lawv lub cev tshwj xeeb: hardness, luster, xim, streak, tshwj xeeb gravity, cleavage, tawg, thiab tenacity
Dab tsi yog cov yam ntxwv ntawm cov hlau nyob rau hauv lub sij hawm?
Lawv yog cov khoom (tshwj tsis yog mercury, Hg, kua). Lawv ci ntsa iab, zoo conductors ntawm hluav taws xob thiab cua sov. Lawv yog cov ductile (lawv tuaj yeem kos rau hauv cov xov hlau nyias). Lawv yog cov malleable (lawv tuaj yeem yooj yim hammered rau hauv cov ntawv nyias nyias)
