[@terrydillon9323]

Thank you also wish someone would also talk about the the importance of the mucus substances in the woman’s egg that carry substances that create life, some people think it is just the male sperm that creates life and that women just carry the baby.

[@nadiakeaton5680]

what does 2n and n x 2 and all that mean? im so confused

[@raidantarctica7551]

What's the chemical formula for it?

[@mrx3430]

what are autosomes ?

[@ilmarabbayani8407]

when it become spermatosit primer, why the cell become bigger than before?

[@ahmedansari7982]

but in meiosis 1 cell divides into 4 cells. then how come it is divided into 2

[@caydaruuzmaxamed2110]

Good

[@tylercrays7021]

I love the video, helping me in A&P
but when you show the diagram of spermatogenesis i wish it was flipped with the basement membrane on the bottom.... it keeps freaking me out it's on top haha

[@tylercrays7021]

also i believe it's important to mention this occurs over two and a half months

[@Honey_sohail]

Hey can you please tell me at ehat age you reach puberty? I know it sounds a lil goofy but yeah if anybody knows

[@rithu4438]

its different for people but generally around your teens. Like 11-15. It also depends on the sex of the person. Males hit puberty at around 11 and females at around 12. I hope this helped xx

[@kartikranipa7086]

Okay

[@Katsukisaud]

whao thanks

[@rifanbudi34]

Human creation in Quran
وَلَقَدۡ خَلَقۡنَا ٱلۡإِنسَٰنَ مِن سُلَٰلَةٖ مِّن طِينٖ
We have created man from an extract of clay.
(Surah Al-Mu'minun, verse 12)
ثُمَّ جَعَلۡنَٰهُ نُطۡفَةٗ فِي قَرَارٖ مَّكِينٖ
Then We made him a sperm-drop in a firm resting place.
(Surah Al-Mu'minun, verse 13)
ثُمَّ خَلَقۡنَا ٱلنُّطۡفَةَ عَلَقَةٗ فَخَلَقۡنَا ٱلۡعَلَقَةَ مُضۡغَةٗ فَخَلَقۡنَا ٱلۡمُضۡغَةَ عِظَٰمٗا فَكَسَوۡنَا ٱلۡعِظَٰمَ لَحۡمٗا ثُمَّ أَنشَأۡنَٰهُ خَلۡقًا ءَاخَرَۚ فَتَبَارَكَ ٱللَّهُ أَحۡسَنُ ٱلۡخَٰلِقِينَ
Then We turned the sperm-drop into a clot, then We turned the clot into a fetus-lump, then We turned the fetus-lump into bones and We clothed the bones with flesh; thereafter We developed it into another creature. So glorious is Allah, the Best of the creators.
(Surah Al-Mu'minun, verse 14)
Thanks

[@kaylag6577]

Except secondary spermatocytes are diploid...

[@vivianeddm]

Your voice is actually very similar to Meredith Grey's!

[@kashaff22]

wow

[@Cheesedragon117]

Thank you Watson Amelia for explaining sperm 🔥🔥🔥

[@gump155]

Congratulations for the video. There is a little mistake on 3:57, the primary spermatocyte already is undergoing meiosis.

[@safuraayman2618]

Spermatogonia multiply first by mitosis to increase in number and some of them differentiate into primary Spermatocytes that undergo meiosis

[@zannatul23]

ur voice is cute miss!
