GenaCL600 [577]

Answer:

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

  1. <em>Sperm fertilizes egg .</em>
  2. <em>Cell divides. </em>
  3. <em>Implants size and weight increase greatly. </em>
  4. <em>Different cell layers form .</em>
  5. <em>Organs and limbs form embryo. </em>
  6. <em>Heartbeat/movements detected .</em>
  7. <em>Movements strengthened .</em>
  8. <em>Organ systems mature .</em>
  9. <em>Baby is born. </em>

Explanation:

  1. <u>Sperm fertilizes egg</u>: it is the process called fertilization, which consists of the union of the paternal gametes to originate the zygote.
  2. <u>Cell divides</u>: Once the zygote has formed, it undergoes successive divisions by mitosis, to originate the different structures.
  3. <u>Implants size and weight increase greatly</u>: successive divisions cause the implanted zygote to progressively increase in size.
  4. <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.
  5. <u>Organs and limbs form embryo</u>: from the three embryonic leaves the different apparatuses and sisythems of the embryo are formed.
  6. <u>Heartbeat / movements detected</u>: Initiates the function of organs such as the heart and extremities.
  7. <u>Movements strengthened</u>: movements in the embryo are more continuous and defined.
  8. <u>Organ systems mature</u>: the nervous, cardiovascular, digestive and respiratory systems, among others, are suitable for birth.
  9. <u>Baby is born</u>.

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