Lub acrosome yog ib qho tshwj xeeb membranous organelle nyob dhau ntawm qhov anterior ntawm cov phev nucleusuas tau txais txiaj ntsig zoo thoob plaws hauv evolution. Qhov no acidic vacuole muaj ib tug xov tooj ntawm hydrolytic enzymes uas, thaum secreted, pab cov phev nkag mus rau lub qe lub tsho tiv no.
Acrosome yog dab tsi thiab nws txoj haujlwm?
Nyob rau hauv tib neeg txiv neej phev, lub acrosome yog ib tug vesicle nyob rau ntawm nws lub ntsis. Nws muaj cov enzymes soluble proteolytic. Thaum cov phev los nyob rau hauv kev sib cuag nrog lub zes qe menyuam muaj acrosome cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no ua kom cov phev tawg los ntawm lub tsho tiv thaiv ntawm lub qe uas yog zona pellucida.
Acrosome nyob rau hauv phev nyob qhov twg?
Lub acrosome yog ib qho organelle uas tsim dhau ntawm ib nrab ntawm lub taub hau hauvcov spermatozoa (sperm cells) ntawm ntau cov tsiaj suav nrog tib neeg. Nws yog lub hau zoo li tus qauv muab los ntawm Golgi apparatus.
Acrosome nyob rau hauv cov phev cell yog dab tsi?
Lub acrosome yog ib yam tshwj xeeb ntawm organelle nrog lub hau zoo li tus qauv uas npog qhov anterior ntawm lub taub hau ntawm cov spermatozoon. Lub acrosome yog muab los ntawm Golgi apparatus thiab muaj cov enzymes digestive.
Lub luag haujlwm tseem ceeb hauv acrosome yog dab tsi?
Cov tshuaj tiv thaiv acrosome yog ib kauj ruam tseem ceeb hauv kev sib cuam tshuam gamete hauv txhua hom, suav nrog txiv neej. Nws tso cai rau spermatozoa nkag mus rau zona pellucida thiab fuse nrog oocyte membrane.

Ntawm qhov chaw twg tsis pom los ntawm qhov pom sab hauv?
Lub qhov ntswg zoo tshaj plawsyog nyob tom qab thiab yog li tsis pom nyob rau sab xub ntiag. Cov duab 9.1, 9.3, 9.5, 9.7, thiab 9.10 N/A Pab txhawb rau anterior cranial fossa; tsim ib feem ntawm qhov ntswg septum thiab qhov ntswg kab noj hniav;
Koj puas tuaj yeem ua qhov muag pom qhov pom kev zoo nkauj?
Eyepiece projection astrophotography Koj tsuas yog kab lub koob yees duab lo ntsiab muag nrog qhib lub qhov muag thiab sim ntes qhov pom pom los ntawm lub koob yees duab ntawm qhov loj. Thaum ntxov, kuv tau tua ntau cov duab astrophotography siv txoj kev no los ntawm kuv Orion SkyQuest Dobsonian telescope .
Qhov qhov muag tsis pom ntawm lub tsheb thauj khoom nyob qhov twg?
Tsev tsheb ciav hlau qhov muag tsis pom muaj xws li: Ncaj nraim rau pem hauv ntej ntawm lub tsheb thauj khoom mus txog 20 ko taw Ncaj nraim hauv qab lub tsheb thauj khoom li 30 ko taw Txhua sab ntawm lub tsheb thauj mus rau sab nraub qaum Tam sim ntawd hauv qab thiab qab tus neeg tsav tsheb qhov rais Puas muaj qhov muag tsis pom kev tsheb thauj mus los?
Qhov kev pom twg pom kev tsis sib haum xeeb yog qhov tsim nyog?
Thaum tib neeg kev sib raug zoo pom tau txais kev sib haum xeeb ntawm lub koom haum ua ib feem tseem ceeb, kev sib cuam tshuam kev pom ntawm-kev tsis sib haum xeeb ntawm lub koom haum yuav siv tib lub tswv yim ib kauj ruam ntxiv. Nws qhia tias qhov kev tsis sib haum xeeb tsis tu ncua, tsawg kawg yog qhov tsim nyog thiab muaj txiaj ntsig zoo rau ib pab pawg .
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
