A lichen tsis yog ib yam kab mob; Nws yog ib qho kev sib koom ua ke ruaj khov ntawm cov kab mob fungus thiab algae thiab / lossis cyanobacteria. Cov lichen symbiosis yog xav tias yog kev sib koom ua ke, txij li ob qho tib si fungi thiab photosynthetic koom tes, hu ua photobionts, tau txais txiaj ntsig.
Tsuas yog li ntawd, vim li cas lichen yog kev sib raug zoo?
Cov kws tshawb fawb xav tias a kev sib raug zoo xws li qhov no yuav tau tso cai rau cov nroj tsuag ua ntej colonize thaj av. A lichen yog ib yam kab mob uas tshwm sim los ntawm kev sib nrig sib kev sib raug zoo nruab nrab ntawm ib tug fungus thiab ib tug photosynthetic kab mob. Cov photosynthesizer tau txais txiaj ntsig los ntawm dej thiab cov as-ham absorbed los ntawm fungus.
Qhov thib ob, yog lichens eukaryotic? Lichens yog ib tug symbiotic koom haum ntawm ib tug fungus thiab ib tug alga. Cov alga tej zaum yuav yog prokaryotic xiav-ntsuab alga lossis a eukaryotic tshuaj unicellular alga. Lichens Yog li ntawd, tsis txhob koom nyob rau hauv ib lub nceeg vaj. Lichens feem ntau yuam kev rau mosses uas yog cov nroj tsuag muaj tseeb.
Tsis tas li ntawd, lub luag haujlwm ntawm fungus nyob rau hauv lichen yog dab tsi?
Keeb Kwm teb: Dab tsi yog luag hauj lwm ntawm algae thiab fungi hauv lichen ? Cov fungi absorbs dej thiab minerals thiab muab lawv rau algae. Cov algae npaj zaub mov nrog lawv nrog kev pab ntawm chlorophyll. Cov zaub mov npaj tau muab faib rau fungi Raws li, nws yog heterotrophic.
Puas yog lichens parasitic los yog kev sib nrig sib?
Lichen cov koom haum tuaj yeem yog cov piv txwv ntawm kev sib raug zoo , commensalism los yog txawm kab mob parasitic , nyob ntawm hom. Muaj pov thawj los qhia tias tus lichen symbiosis yog kab mob los yog commensalistic, tsis yog kev sib raug zoo.

Dab tsi organelle suav hais tias yog lub Hoobkas vim tias nws siv rau hauv raw?
Chloroplast tig hnub ci, carbon dioxide, thiab dej rau hauv cov zaub mov (qabzib). Dab tsi organelle raug suav hais tias yog 'lub Hoobkas', vim tias nws siv cov khoom siv raw thiab hloov mus rau cov khoom lag luam ntawm tes uas tuaj yeem siv los ntawm lub xovtooj? Cell membrane tiv thaiv lub cell; tswj qhov nkag mus rau hauv thiab tawm ntawm tes, kev sib txuas lus
Vim li cas monumental architecture ib txwm raug suav hais tias yog tus yam ntxwv ntawm kev vam meej thaum ntxov?
Lwm qhov tseem ceeb ntawm ntau kev vam meej yog monumental architecture. Hom architecture no feem ntau tsim los rau kev nom kev tswv, kev cai dab qhuas, lossis rau pej xeem zoo. Cov kev vam meej feem ntau tsim los ntawm cov zej zog ua liaj ua teb uas muab zaub mov txaus los txhawb cov nroog
Vim li cas cov nroj tsuag raug suav hais tias yog yam muaj sia?
Cov ntoo raug suav tias yog cov khoom muaj sia vim tias lawv ua tiav txhua yam ntawm cov khoom muaj sia: Kev Loj Hlob: Los ntawm photosynthesis thiab los ntawm kev nqus cov as-ham, minerals thiab dej los ntawm lawv cov hauv paus hniav, ntoo loj hlob. Kev yug me nyuam: Pollenand noob ua cov ntoo tshiab. Excretion: Ntoo tshem tawm pov tseg (oxygen)
Yog vim li cas trp operon suav hais tias yog ib tug repressible operon?
Lub tryptophan (trp) operon system yog ib hom repressible operon system. Thaum tryptophan tam sim no, nws khi lub trp repressor thiab induces ib tug conformational hloov nyob rau hauv cov protein, ua rau nws khi tus neeg teb xov tooj trp thiab tiv thaiv transcription (operon yog repressed)
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
