Cov Khoom Ntawm Lub Neej. Txhua yam muaj sia nyob sib koom ob peb tus yuam sij yam ntxwv los yog kev ua haujlwm: kev txiav txim, rhiab heev los teb rau ib puag ncig, kev yug me nyuam, kev loj hlob thiab kev loj hlob, kev tswj hwm, homeostasis, thiab lub zog ua haujlwm. Thaum saib ua ke, cov no yam ntxwv pab kom txhais lub neej.
Hais txog qhov no, cov yam ntxwv zoo li cas los ntawm txhua yam muaj sia nyob?
Ntawm no yog cov npe ntawm cov yam ntxwv sib koom los ntawm cov tsiaj nyob:
- Cellular koom haum.
- Kev tsim tawm.
- Metabolism.
- Homeostasis.
- Keeb kwm.
- Teb rau stimuli.
- Kev loj hlob thiab kev loj hlob.
- Adaptation los ntawm evolution.
Ib yam li ntawd, vim li cas cov kab mob thiaj li zoo sib xws? Cov kab mob ntawm tib hom zoo sib xws . Cells tsim cov ntawv luam ntawm DNA thaum lub sij hawm yug me nyuam los ntawm kev koom nrog ntau cov txheej txheem tshuaj. Yog li cov ntawv luam ntawm DNAgenerated yuav yog zoo sib xws raws li tus txheej txheem yog tib yam tab sis tej zaum yuav tsis yog ib txwm zoo tib yam vim variations.
Tsis tas li ntawd, txhua yam kab mob muaj sia zoo li cas?
Tswvyim 40 Tej yam muaj sia qhia commongenes. Txhua yam muaj sia nyob khaws cov ntaub ntawv genetic siv tib lub molecules - DNA thiab RNA. Sau nyob rau hauv txoj cai noob caj noob ces ntawm cov molecules yog yuam pov thawj ntawm qhov sib koom caj ces ntawm txhua yam muaj sia.
Dab tsi yog 5 yam ntawm txhua yam muaj sia?
Cov no yog xya yam ntxwv ntawm cov tsiaj muaj sia
- 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.

Vim li cas txhua yam muaj sia yuav tsum muaj DNA?
Tag nrho cov kab mob uas muaj sia nyob yuav tsum muaj vim nws ua raws li cov khoom siv caj ces (muaj cov noob caj noob ces) uas khaws cov ntaub ntawv lom neeg. Tsis tas li ntawd, DNA encodes cov kab ke ntawm cov amino acid residues (rau protein synthesis) siv ib tug triplet code ntawm neucleotides (genetic code) tom qab transcribing rau RNA
Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
Dab tsi yog 3 yam sib txawv ntawm kev vam meej ntawm cov kab mob muaj sia?
Sau peb hom kev sib txawv ntawm cov kab mob muaj sia nyob thiab muab piv txwv ntawm txhua tus. Mutualism - ib tug noog noj ntawm ib tug alligators cov hniav. Commensalism - ib tug orchid nyob rau hauv ib tsob ntoo ceg Parasitism - ib tug yoov tshaj cum tom koj txhais caj npab. 3
Puas yog ib qho kab mob ntawm tes yog ib yam muaj sia nyob?
Cov kab mob (singular: kab mob) yog ib pawg loj ntawm cov kab mob nyob. Feem ntau yog cov microscopic thiab unicellular, nrog cov qauv ntawm tes yooj yim uas tsis muaj cell nucleus, thiab cov organelles xws li mitochondria thiab chloroplasts. Cov kab mob muaj ntau tshaj plaws ntawm tag nrho cov kab mob
