Piv txwv ntawm Prokaryotes:
- Cov kab mob Escherichia Coli (E. coli)
- Streptococcus kab mob.
- Streptomyces Av Kab mob .
- Archaea.
Ntawm no, qee qhov piv txwv ntawm cov hlwb prokaryotic yog dab tsi?
Ib piv txwv yog E. coli. Feem ntau, prokaryotic hlwb yog cov uas tsis muaj daim nyias nyias nyias. Infact "pro-karyotic" yog Greek rau "ua ntej nucleus". Dhau li ntawm cov kab mob, cyanobacteria (xiav-ntsuab algae) yog ib pawg loj ntawm prokaryotes.
Qhov thib ob, dab tsi yog qee qhov piv txwv ntawm prokaryotes thiab eukaryotes? Prokaryotic cov hlwb tsis muaj lub cev hauv cellular (organelles), thaum eukaryotic tshuaj cov cell muaj lawv. Piv txwv ntawm prokaryotes yog cov kab mob thiab archaea. Piv txwv ntawm eukaryotes yog protists, fungi, nroj tsuag, thiab tsiaj txhu (txhua yam prokaryotes ).
Ib yam li ib tug yuav nug, 2 piv txwv ntawm eukaryotic hlwb yog dab tsi?
Tag nrho cov protists, fungi, nroj tsuag thiab tsiaj txhu yog cov piv txwv ntawm eukaryotes
- Cov Protists. Protists yog ib-celled eukaryotes.
- Lub fungi. Fungi tuaj yeem muaj ib lub cell lossis ntau lub hlwb.
- Cov nroj tsuag. Tag nrho ntawm kwv yees li 250,000 hom nroj tsuag - los ntawm cov mosses yooj yim mus rau cov paj ntoo - yog cov eukaryotes.
- Cov Tsiaj.
Puas yog amoeba ib qho piv txwv ntawm prokaryotic cell?
Nyob rau hauv sib piv rau prokaryotic hlwb , eukaryotic kab mob hlwb muaj kev txhim kho heev. Cov kab mob thiab Archaea yog prokaryotes , thaum tag nrho lwm yam kab mob nyob yog eukaryotes. Amoebae yog eukaryotes uas nws lub cev feem ntau muaj ib leeg cell . Lawv DNA tau ntim rau hauv acentral cellular compartment hu ua thennucleus.

Dab tsi yog qhov sib piv thiab piv txwv?
Inverse proportion. Inverse proportions tshwm sim thaum ib tus nqi nce thiab qhov txo qis. Piv txwv li, ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
