Place the events of fertilization and implantation in order. 1. Implantation of the developing embryo. 2. The developing embryo
ANTONII [103]

Answer:

The correct order is

5, 4 , 3, 2, 1

Explanation:

The first stage is the fusion of sperm  with egg in fallopian tube which induces chemical reactions that prevents fusion of multiple sperm with one egg. This is known as preventing polyspermy.

After this the fused egg starts dividing and growing through the process of mitosis. The growing zygote reaches the stage of morula after few cell division and continues the division process till it reaches the stage of blastocyst.

The blastocyst now move down the fallopian tube to attach to the wall of uterus. This stage is known as implantation.

Hence, the correct order is 5, 4 , 3, 2, 1
