Question

Aman was very surprised when he saw his newborn sister. Because on the same day his teacher taught them that human beings are developed from a single cell. What is the right sequences of our development inside the female body. *

a)young one→ zygote→foetus → embryo
b) zygote→embryo→ foetus → young one
c)zygote→foetus→ embryo →young one
d) Foetus→ zygote→ young one → embryo​

Answer 1

The right sequence of our development inside the female body are the zygote→embryo→ foetus → young one

Explanation:

The development of a newborn inside the female body occurs in the following way:

1. The process of developing the embryo is so-called embryogenesis which occurs inside the female's body.
2. When a sperm meets an egg in the ovary it first forms a zygote which is single-celled.
3. The zygote will further form more cells to develop as an embryo(multiple cells).
4. Fertilization of the embryo will reach a final stage called the fetal stage where the foetus is formed successfully.
5. Thus, the correct sequencing of the development of a newborn from a single cell is as follows: zygote→embryo→ foetus → young one

Answer 2

Answer: the correct sequence is zygote embryo foetus and young one

Explanation: the zygote is formed by the fusion of the nuclei of the sperm and egg and it is unicellular structure and is produce after the processes of fertilization and well described body is absent .whereas the embryo is an early stage of human development in which organs are critical body structures are formed and foetus is early atage of embryo which resembles a human being and a multicellular structure and produced after cell and labor division then is the human being called as young one is formed.
