Question

The mother gives birth to the child when the development of the __________ is complete.
A. Uterus
B. Zygote
C. Foetus
D. None of the above

Answer 1

Parturition is defined as the act of childbirth. During parturition or childbirth a unique and well- regulated interplay of the hormones is seen in the body of a female. Parturition is known as childbirth. It is likewise called labour. It is the mechanism of signaling the onset of labour (or) a system of handing over an infant after the entirety of being pregnant. The advanced infant is born with the discharge of cortisol.

Complete answer:
Option A: Uterus is the part of the female reproductive tract and is the site of implantation and the development of foetus. So, a mother can never give birth to a child.
Therefore, Option A is not correct.
Option B: A zygote is a structure formed after the fusion of the male and the female gametes. During development the zygote is transformed to a foetus through morula, blastula and a gastrula stage. The foetus later develops into a complete child before a mother gives birth.
Therefore, Option B is not correct.
Option C – A fetus is the structure formed after embryonic development. The foetus develops into a mature baby which is given birth by the mother. This whole process of foetal development is carried out inside the uterus of the female.
Thus, Option C is correct.
Option D: None of the above, this option is eliminated as the development of the foetus is complete when a mother gives birth to a child.
Thus, Option D is also not correct.

Hence, Option C is the correct answer.

Note:
Development of an organism from a single-celled zygote to a multicellular organism is complicated and well organized. The early tiers of embryonic improvement also are vital for making sure the health of the organism. In basic developmental biology the term embryo and foetus are used very often but they are distinct from each other based on their developmental ages.
