Place the following in order from first to last
Nidation (Implantation)
Meiosis
Uterine lining called decidua
Zygote
Fertilization
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.

Explanation
A. A Category 1 fetal heart rate tracing is considered normal, with a baseline FHR between 110-160 bpm, moderate variability, accelerations, and early decelerations, all of which are reassuring signs.
B. Category 2 tracings are indeterminate and would show a pattern of abnormal FHR, but not severe enough to be classified as Category 3.
C. Category 3 tracings are abnormal, characterized by absent variability and significant decelerations, suggesting fetal distress or other severe issues.
D. Category 4 is not a recognized category in fetal heart rate classification.
