Biology raws li ib tug science

Biology - qhov kev kawm ntawm nyob xwm, cov kev cai tswj nws. Yuav ua li cas yog kev kawm txog biology? Biology raws li ib tug science kawm cov qauv, keeb kwm, kev loj hlob, muaj nuj nqi thiab evolution uas muaj sia nyob. Biology Life Sciences.

Lub hauv paus biology yog 5 yooj yim hauv paus ntsiab lus. Qhov no cell tshawb xav, homeostasis, noob caj noob ces, evolution, thiab lub zog.

Lub homphiaj ntawm kev kawm biology yog cov cim ntawm, thiab piav qhia txog cov kev dab thiab cov txheej xwm rau tag nrho cov kab mob. Biology raws li science tso cai rau noog paub txog dab tsi tshwm sim nyob rau hauv lub nyob ntiaj teb no, khaws lawv nyob txawv xov xwm thiab siv raws li xav tau.

Lom sciences raug muab faib los ntawm hom ntawm qhov kev kuaj kab mob.

Tshuaj xyuas tsiaj txhuv tshuaj xyuas tsiaj, botany - cov nroj tsuag thiab microbiology kev tshawb fawb ib leeg-celled microorganisms.

Sab hauv, biology thaum ib tug science yog faib mus rau hauv teb-scale kev tshawb fawb los yog kev siv. Yog li, cov kev kawm ntawm txoj kev tshawb ntawm histology thiab lub cev yog cov qauv ntawm lub cev thiab cov nqaij mos, noob caj noob ces - cov kev hloov ntawm caj ces, biochemistry - tshuaj bases ntawm lub neej, molecular biology uas - sis lom molecules, physiology - tshuaj thiab lub cev functions ntawm lub nruab nrog cev thiab lwm tus neeg.

Tej yam tshwm sim ntawm ib tug sia :

- nws muaj ib tug complex nrog cov qauv;

- nyob rau hauv ib feem ntawm lub cev muaj ib lub hom phiaj, thiab nws thiaj li tawm tau nws cov kev khiav dej num;

- retrieves transforms thiab siv lub zog los ntawm cov ib puag ncig, sib pauv ntawm qhov teeb meem thiab lub zog;

- teb rau tej kev hloov (mus rau sab nraud stimuli);

- muaj peev xwm kom pab tau, uas yog, tus kab mob no hloov mus rau lawv ib puag ncig;

- muaj peev xwm rau cov me nyuam;

-sposobnost mus rau lub evolution ntawm (ib tug kev hloov los ntawm tej yam yooj yim mus rau lub complex).

Ntau haiv neeg nyob ntiaj teb no thiab muaj ib tug tham qauv. Lub koom haum ntawm lub neej yog nqa tawm ntawm ntau.

1. Lub qis tshaj theem - molecular lug.
2. Cellular theem.
3. Hloov khoom nruab nrog - cov ntaub so ntswg theem. Nyob rau theem no, cov kab mob yog multicellular.
4. Tag nrho cov kab mob.
5. Pejxeem-hom theem.
6. Theem ecological zej zog, piv txwv li, cov zej zog ntawm tag nrho cov hom, uas nyob hauv lub chaw uas zoo heev.
7. Biosphere. Nws yog lub totality ntawm lub neej nyob rau lub ntiaj teb.

Holistic (nyob), lub system muaj cov nram qab nta:

- txoj kev sib sau ntawm cov tshuaj muaj pes tsawg leeg;

- qhib siab dawb paug ntawm nyob systems;

- nyob systems - self-regulating, self-organizing, self-tswj, self-me nyuam system;

- variability;

- muaj peev xwm los tsim thiab loj hlob, uas yog ib qho kev nce nyob rau hauv hnyav thiab loj, lub tsos ntawm tshiab qualities thiab nta;

- kev xaiv thiab kev ntseeg siab.

Txoj kev ntawm txoj kev tshawb.

Biology rau txoj kev tshawb no ntawm nyob kab mob siv ib tug ntau yam ntawm txoj kev. Piv txwv li, cov muaj xws li:

- Xyuas.

Nws ua rau nws tau qhia hais tias yuav khoom thiab txawv tshwm sim.

- Sim.

Simulated teeb meem no nyob rau hauv uas lub qhia tau thaj chaw ntawm lub kawm lom khoom.

- Sib Piv.

Nws tso cai rau koj mus teem ntau rau cov kev cai ntawm lub ntau yam tshwm sim.

- Keeb kwm txujci.

Paub yuav tsum raws li muaj cov ntaub ntawv nyob rau hauv cov organic ntiaj teb no.

Rau txoj kev tshawb no ntawm lom khoom siv ntau hom kev kawm. Cov no yog cov: computers, rub kom pom loj, tshuaj analyzers, ultracentrifugation, thiab ntau lwm yam khoom siv.

Biology raws li ib tug science yog qho tseem ceeb heev rau cov neeg, txij li thaum cov kev tshawb fawb uas yog nqa tawm, qhia rau peb paub ntau ntxiv txog cov txheej txheem thiab phenomena noj qhov chaw nyob rau hauv lub nyob ntiaj teb no thiab siv no invaluable kev nyob rau hauv lawv lub neej txhua hnub, los daws kom tau lub ntiaj teb no tej teeb meem. Paub txog cov kev cai biology yuav daws tau cov tswv yim muaj teeb meem, piv txwv li, muab zaub mov rau cov pejxeem. Agriculture thiab tsiaj husbandry yog raws li nyob rau hauv biology. Cov tshuaj yuav tsis ua yam uas tsis muaj kev txawj ntse ntawm cov qauv (lub cev) ntawm tib neeg lub cev.
