Fertilization

Answer and Explanation

The Correct Answer is B, E, D, F, A, C

Meiosis is the process of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and egg). This is the first step in the process of reproduction.

Fertilization occurs when a sperm cell unites with an egg cell to form a zygote. This marks the beginning of the formation of a new organism.

The zygote is the single-cell result of fertilization. It will undergo several mitotic divisions to form a blastocyst.

The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass that will eventually develop into the embryo.

Nidation, or implantation, occurs when the blastocyst attaches to the uterine wall.

After implantation, the endometrium is called the decidua, which provides a nourishing environment for the developing embryo.
