Question

Arrange the following steps in order.

i. Sperms survive for a short period in the vagina's acidic secretions.
ii. The sperms travel through the uterus followed by the fallopian tube.
iii. The sperms which survive reach the cervix.
iv. The sperms then reach the egg for fertilization.

• A. i - ii - iii - iv
• B. iv - iii - ii - i
• C. i - iii - ii - iv
• D. iv - ii - iii - i

Answer 1

The correct option is C

i - iii - ii - iv

The sperms first enter the vagina where they survive for a short time in the acidic secretion. They then reach the cervix from where the surviving sperms move to the uterus followed by fallopian tube. At last, they fuse or fertilize with the egg in the fallopian tube.
