📈Milliy sertifikat darajasidagi test

Nomalum hayvon 3 marta meridian bolinish bilan 4 marta ekvatrial bolinishi natijasida blastamerlardagi xromasomalar farqi 15872 ni tashkil qilsa tuxum hujayrasida nechta xromasoma boladi?

A)64 B)16 C)32 D)128

Meridian = M

Ekvatorial = E

M - M - E - M - E - M - E - M - E

2- 4- 8- 16- 32- 64- 128- 256- 512

512x - 16x = 496x

15872/496x

x= 32 ta xromasoma

32/2= 16 ta tuxum hujayradagi

✅Javob : B) 16

1mol --------> 2ATF

x = 10 ------> 20 mol

180gr --------> 1mol

630gr -----> 3.5 mol

10 - 3.5 = 6.5 mol *to'la parchalangan

10 -------> 100%

6.5 -------> x = 65%
