Major . Cov Human Biology Major muab ib txoj hauv kev rau kev nkag siab tib neeg dab los ntawm lom , kev coj cwj pwm, kev coj noj coj ua, thiab kev coj noj coj ua. Qhov kev pab cuam npaj majors mus nrhiav kev cob qhia qib siab hauv kev tshaj lij lossis kev kawm tiav.
Tib neeg kuj nug, kev kawm txog tib neeg biology yog dab tsi?
Tib neeg biology yog ib cheeb tsam interdisciplinary ntawm kawm uas tshuaj xyuas tib neeg los ntawm kev cuam tshuam thiab kev sib cuam tshuam ntawm ntau yam kev sib txawv xws li noob caj noob ces, evolution, physiology, lub cev, kev kis kab mob, anthropology, ecology, khoom noj khoom haus, cov noob caj noob ces, thiab kev coj noj coj ua.
Tsis tas li ntawd, qhov txawv ntawm tib neeg biology thiab biology yog dab tsi? Kuv xav tias tsis tu ncua biology npog txhua yam uas biology encompasses xws li hlwb, nroj tsuag, ecology, qee ceg ntawm cov organic chemistry. Biology yog generic thiab nws npog txhua yam ntawm txhua yam nyob. Tib neeg biology yog subfield biology uas tsuas tham txog lom qauv ntawm tib neeg nkaus xwb.
Yog li ntawd, tib neeg biology puas yog qib zoo?
A Human Biology degree muab lub hauv paus muaj zog rau ntau txoj haujlwm kev ua neej nyob. Tej kev txawj hloov pauv tau npaj tib neeg biology cov tub ntxhais kawm kom ua tiav thiab muaj txiaj ntsig zoo hauv kev ua haujlwm.
Vim li cas koj thiaj kawm txog biology?
Peb yog vim li cas los kawm Biology : Kawm biology muab cov tub ntxhais kawm tau yooj yim dua hauv lawv txoj kev ua haujlwm. Tsis txhob tsom mus rau ib qho kev qhuab qhia tshwj xeeb, biology majors muaj peev xwm kawm txog txhua yam ntawm biology , zoo li ecology, rau hlwb, mus rau marine lub neej. Zoo, los ntawm kev kawm Biology koj tuaj yeem ua ob qho tib si.

Dab tsi yog qhov tseem ceeb ntawm nomenclature hauv biology?
Cov npe kev tshawb fawb yog cov ntaub ntawv Txhua hom kev lees paub hauv ntiaj teb (tsawg kawg hauv txoj kev xav) tau muab ob lub npe tshawb fawb. Qhov no yog hu ua 'binomial nomenclature.' Cov npe no tseem ceeb vim tias lawv tso cai rau tib neeg thoob plaws ntiaj teb sib txuas lus tsis meej txog hom tsiaj
Dab tsi yog ob qho laj thawj tseem ceeb ntawm kev mob caj ces hauv tib neeg?
Muaj peb hom kab mob caj ces: Ib hom kab mob ib leeg, qhov kev hloov pauv cuam tshuam rau ib lub noob. Sickle cell anemia yog ib qho piv txwv. Chromosomal disorders, qhov twg chromosomes (los yog ib feem ntawm chromosomes) ploj lawm los yog hloov. Cov kab mob nyuaj, qhov twg muaj kev hloov pauv hauv ob lossis ntau lub noob
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
