The likelihood of survival is impacted because:
1. The fetus does not have fully developed lungs: Without fully developed lungs, the fetus would not be able to breathe on its own once outside the womb, which is crucial for survival.
2. The fetus cannot control its own body functions: This lack of control over essential bodily functions can hinder the fetus's ability to adapt to changes in the environment after birth, affecting survival chances.
3. The fetus is not able to store its own nutrients: Inability to store nutrients independently can lead to challenges in maintaining proper nutrition levels required for growth and development, which can affect the overall health and survival of the fetus.
