Gemmules yog cov buds sab hauv pom nyob rau hauv daim txhuam cev thiab koom nrog hauv kev yug me nyuam asexual. Nws yog ib qho asexually reproduced loj ntawm cov hlwb, uas muaj peev xwm ntawm kev loj hlob mus rau hauv ib tug tshiab kab mob xws li, ib tug neeg laus daim txhuam cev.
Kev sib raug zoo, koj txhais li cas los ntawm Gemmule tsim?
Ib qho asexually tsim loj ntawm cov hlwb, uas yog muaj peev xwm ntawm kev loj hlob mus rau hauv ib tug tshiab kab mob los yog mus rau hauv ib tug neeg laus cov dej qab zib sponge yog hu ua a Gemmule . Lawv yog me paj zoo li cov hlwb, uas raug tsim los ntawm daim txhuam cev kom tiv taus ib puag ncig tsis zoo. Ib daim txhuam cev dej tshiab tsim tawm ob qho tib si los ntawm kev sib deev thiab asexually.
Ib yam li ntawd, dab tsi yog budding hauv biology? Paj tawg yog hom kev yug me nyuam asexual nyob rau hauv uas ib tug tshiab kab mob tshwm sim los ntawm ib tug outgrowth los yog bud vim cell division ntawm ib qho chaw. Cov buds no loj hlob mus rau hauv cov tib neeg me me thiab, thaum loj hlob tiav, tshem tawm ntawm niam txiv lub cev thiab dhau los ua cov neeg ywj pheej tshiab.
Lub luag haujlwm ntawm Archaeocytes yog dab tsi?
Archaeocytes tseem ceeb heev rau kev ua haujlwm ntawm daim txhuam cev. Cov hlwb no yog totipotent, uas txhais tau hais tias lawv tuaj yeem hloov mus rau tag nrho lwm hom sponge hlwb. Archaeocytes noj thiab zom cov zaub mov uas ntes tau los ntawm choanocyte dab tshos thiab thauj cov as-ham mus rau lwm lub hlwb ntawm daim txhuam cev.
Vim li cas Gemmules pom feem ntau hauv cov sponges dej tshiab?
Hauv cov dej tshiab , gemmules tuaj yeem muaj sia nyob ib puag ncig ib puag ncig xws li kev hloov pauv ntawm qhov kub thiab txias. Lawv ua hauj lwm rau recolonize lub vaj nyob ib puag ncig tej yam kev mob stabilize. Gemmules muaj peev xwm txuas rau lub substratum thiab tsim ib qho tshiab daim txhuam cev.

Dab tsi yog qeb yog marine biology nyob rau hauv?
Marine biology yog ib ceg ntawm biology. Nws muaj kev sib raug zoo nrog oceanography thiab tej zaum yuav raug suav hais tias yog ib qho kev ua haujlwm ntawm kev tshawb fawb hauv dej hiav txwv. Nws tseem suav nrog ntau lub tswv yim los ntawm ecology. Kev tshawb fawb txog kev nuv ntses thiab kev txuag dej hiav txwv tuaj yeem suav hais tias yog ib feem ntawm kev ua liaj ua teb marine biology (nrog rau kev tshawb fawb ib puag ncig)
