Answer:
A genetic drift is defines as the change in the allele frequency of an existing population. It arises as a result of random variation in a population. The rate of genetic drift would be greatest in a small population that are geographically isolated from the parent population. A change in the allele frequency of a population as a result of chance rather than the natural selection.

The canal that extends from the vestibule to the uterus is called the<u> </u><u>vagina</u>.
Vagina is a part of the female reproductive system forming an elastic, muscular part of the female genital tract.

The uterus is a pear shaped, hollow, muscular organ also called the womb which is involved in the process of menstruation and also in the development of the fetus during pregnancy.
Answer:
The prokaryotes uses organ called Pilus during conjugation process.
Explanation:
Pilus is a long thread like appendages which seen in the capsules of the bacteria. During conjugation process, the pilus from the donor bacteria extends and gets attached to the recipient bacteria.
The shared pilus acts as the bridge between the donor as well as the recipient bacteria through which the exchange of genetic information occurs. Thus it can be inferred that during conjugation prokaryotes uses pilus.
