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