Answer :
Final answer:
During artificial insemination in cows, the semen straw must go through the rectum and into the uterus for successful fertilization.
Explanation:
When artificially inseminating a cow, the technician must make sure the semen straw goes through the rectum so it is in the correct position for the semen to be injected into the uterus. The rectum is the final part of the digestive system where waste material is stored before elimination. In the process of artificial insemination, the technician guides the straw through the rectum and into the cervix, which leads to the uterus. This ensures that the semen is deposited in the correct reproductive tract for successful fertilization.
