Tsiaj zoo li protists hu ua protozoa. Nroj zoo li protists hu ua algae. Lawv suav nrog ib leeg-celled diatoms thiab multicellular seaweed. Zoo li cov nroj tsuag, lawv muaj chlorophyll thiab ua zaub mov los ntawm photosynthesis. Hom Ntawm algae muaj xws li liab thiab ntsuab algae, euglenids, anddinoflagellates.
Cov neeg kuj nug, dab tsi yog cais raws li ib tug protist?
Protists yog cov kab mob eukaryotic uas ua tsis tau cais raws li cov nroj tsuag, tsiaj txhu, los yog fungus. Lawv feem ntau yog unicellular, tab sis qee qhov, zoo li algae, yog multicellular. Kelp, los yog 'seaweed,' yog ib tug loj multicellular protist uas muab zaub mov, vaj tse, thiab oxygen rau ntau lub hauv qab dej.
Tom qab ntawd, lo lus nug yog, 4 hom protists yog dab tsi? Piv txwv ntawm protists suav nrog algae, amoebas, euglena, plasmodium, thiab slime pwm. Protists uas muaj peev xwm ntawm photosynthesis suav nrog ntau yam hom ntawm algae, diatoms, dinoflagellates, thiab euglena. Cov kab mob no feem ntau yog unicellular tab sis tuaj yeem tsim cov cheeb tsam.
Raws li txoj cai, 3 hom protist yog dab tsi?
Zaj Lus Qhia
- Tsiaj zoo li protists hu ua protozoa. Feem ntau muaj xws li asingle cell.
- Cov nroj tsuag zoo li protists hu ua algae. Lawv suav nrog ib leeg-celled diatoms thiab multicellular seaweed.
- Fungus zoo li protists yog pwm. Lawv yog cov khoom nqus nqus, pom nyob rau ntawm cov organic decaying.
Hom protist yog amoeba?
Ib amoeba yog ib tug classification ntawm protist (ib leeg-celled eukaryotic kab mob uas tsis yog nroj tsuag, tsiaj, kab mob, los yog fungus) uas yog amorphous nyob rau hauv cov duab. Lawv txav viaforming 'ko taw zoo li' pseudopodia, uas kuj siv rau kev pub noj.

Dab tsi ntawm protist yog amoeba?
Kev faib tawm suav nrog: Naegleria fowleri; Entamoeba histolytica
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Dab tsi yog qhov txawv ntawm N hom semiconductor thiab P hom semiconductor?
Hauv N-hom semiconductor, cov khoom siv hluav taws xob feem ntau yog cov neeg nqa khoom thiab qhov yog cov neeg nqa khoom tsawg. Hauv P-hom semiconductor, qhov yog feem ntau cov neeg nqa khoom thiab cov khoom siv hluav taws xob yog cov neeg tsawg. Nws muaj qhov loj dua electron concentration thiab tsawg lub qhov concentration. Nws muaj qhov loj dua qhov concentration thiab tsawg dua electron concentration
