The prenatal circulation of blood is different than the postnatal circulation, mainly because the lungs are not in use. The fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord. Blood from the placenta is carried to the fetus by the umbilical vein.

An established population that is accustomed to change.
Answer:
<em> 2.The subsequent generations will be less diverse than the original population </em>
Explanation:
<u>A larger population means that there are more genetically diverse organisms in a population. As a result, there will be more genetic diversity in a larger population as compared to a smaller population.</u>
When any disaster occurs, resulting in wiping a larger portion of the population, then the population becomes lesser. As a result, the genetic diversity of the population also decreases.
<u>Hence, a disaster such as the one described in the question will lead to lesser genetic diversity in the coming generations. </u>
