Scope ntawm biology . Biology : Cov kev tshawb fawb uas cuam tshuam nrog kev kawm txog cov qauv, lub koom haum, cov txheej txheem ntawm lub neej, kev sib cuam tshuam, keeb kwm thiab evolution ntawm cov kab mob nyob yog hu ua biology.
Ua raws li qhov kev xav no, dab tsi yog qhov ntawm biology yav tom ntej?
BSc Biology Scope Cov kev kawm tseem muaj ntau lub sijhawm hauv Kev Tshawb Fawb thiab Kev Txhim Kho (R&D), Pharmaceuticals thiab Chemical industries, Public Health and Environmental Protection Sectors, Clinical Research, Waste Management, etc.
Vim li cas peb kawm txog biology sau qee qhov kev kawm txog biology? Biology muab tus kev paub kom muaj kev noj qab haus huv zoo los ntawm kev ua raws a Khoom noj kom zoo, kev tawm dag zog, coj tus cwj pwm zoo thiab lwm yam. Ob peb kab mob ua rau muaj kab mob sib txawv. Cov cwj pwm, chaw nyob, qauv, lub neej voj voog thiab lwm yam ntawm cov kab mob no ua tau yuav kawm nyob rau hauv biology . Yog li ntawd, peb ua tau nyob deb ntawm cov kab mob sib txawv rau a ntau npaum li cas.
Ib yam li ntawd, nws yog nug, dab tsi yog Scope ntawm biological science?
Cov Scope ntawm biological sciences yog dav heev uas suav nrog microbiology, biochemistry, cell biology , evolution, neuroscience, zoology, botany, biotechnology, ecology thiab ntau yam ntxiv nthuav !!
Dab tsi yog txoj haujlwm zoo tshaj plaws hauv biology?
Cov hauj lwm zoo tshaj plaws rau Biology Degree Majors
- Biological Technician.
- Biochemist.
- Genetic Counselor.
- Health Communications Specialist.
- Health Educator.

Dab tsi yog Environmental Science txhais thiab Scope ntawm daim teb?
Environmental science yog qhov kev tshawb fawb uas kawm txog kev sib cuam tshuam ntawm lub cev, tshuaj lom neeg, thiab cov khoom siv roj ntsha ntawm ib puag ncig thiab tseem muaj kev sib raug zoo thiab cuam tshuam ntawm cov khoom no nrog cov kab mob hauv ib puag ncig
Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
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
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
