Online testdagi 30-masala yechimi
Ulotriks ipidagi hujayralarni 5 tasi 3
marta, 3 tasi 5 marta, 4 tasida 4 marta
bo’linish kuzatilsa u xolda jami nechta va
necha xil zoospora xosil bo’ladi
A) 56 ta va 3 xil B) 56 ta va 12 xil
C) 200 ta va 3 xil D) 160 va 3 xil
Yechimi:
1) 2³=8•5=40
2) 2⁵=32•3=96
3) 2⁴=16•4=64
40+96+64=200 ta va 3 xil
Javob: C

Online testdagi 25-masala yechimi
Ulotriks jinsiy va jinssiz ko’payadi. Bunda
xosil bo’lgan zoosporalar va gametalar soni
teng bo’lib, ip xosil bo’lishi uchun hujayradan tushib ketgan xivchinlar soni 480 tani tashkil qilsa u xolda jinsiy
ko’payish natijasida xosil bo’lgan iplar soni
zoosporalardan xosil bo’lgan iplarga
nisbatan qanchaga farq qilishini aniqlang
A) 160 B) 220 C) 80 D) 60
Yechimi
Izogameta – x ---- xivchini 2x
Zoospora – x ------- xivchini 4x
4x+2x=6x
6x=480
x=80 tadan zoospora va izogameta hosil bo'lgan
x ----- x ------ 4x
jinsiy ----- zigota ----- 4 ta ip
y ------------- y ------------- y
jinssiz ----- zoospora ---- 1 ta ip
80 zoosporadan 80 ta ip hosil bo'ladi
2 ta izogametadan —- 1 ta zigota hosil boladi
80 ta izogametadan —- x= 40 ta zigota hosil boladi
1 ta zigota 4 ta yangi ip hosil qilsa umumiy iplar sonini topamiz
1 ------- 4 ta ip
40 ------ x x= 160 ta yangi ip
Farqni topamiz:
80 zoosporadan 80 ta ip
80 izogametadan 160 ta yangi ip 160-80=80 farq Javob: C :@Nuriddinov_Amriddin

Online testdagi 7-masala yechimi Yechimi
Oziq zanjirning har bir trofik darajasida energiyaning 90% i yo‘qoladi faqat 10% i keyingi darajaga o‘tadi.
Bunda oziq zanjirning 10% i tana tuzilishiga 90% i organizm hayot faoliyatini taminlashga sarflanadi.
Bug'doy — 3200 kg
↓↓
Sichqon — 320 kg
↓↓
Ilon — 32 kg
320 kg —- 100%
x kg —— 25%
x=80 kg
Sichqon — 80 kg
↓↓
Ilon — 8 kg organ ekan.
