GenaCL600 [577]

Answer:

The correct order in which development occurs from fertilization of the egg is:

Sperm fertilizes egg .
Cell divides.
Implants size and weight increase greatly.
Different cell layers form .
Organs and limbs form embryo.
Heartbeat/movements detected .
Movements strengthened .
Organ systems mature .
Baby is born.

Explanation:

Sperm fertilizes egg: it is the process called fertilization, which consists of the union of the paternal gametes to originate the zygote.
Cell divides: Once the zygote has formed, it undergoes successive divisions by mitosis, to originate the different structures.
Implants size and weight increase greatly: successive divisions cause the implanted zygote to progressively increase in size.
Different cell layers form: consists of the formation of the embryonic layers -ectoderm, mesoderm and endoderm- from which the tissues and organs of the embryo will be formed.
Organs and limbs form embryo: from the three embryonic leaves the different apparatuses and sisythems of the embryo are formed.
Heartbeat / movements detected: Initiates the function of organs such as the heart and extremities.
Movements strengthened: movements in the embryo are more continuous and defined.
Organ systems mature: the nervous, cardiovascular, digestive and respiratory systems, among others, are suitable for birth.
Baby is born.

When the baby is able to survive outside the womb, birth occurs.
