Answer:

The correct answer is option (B) "She was getting her oxygen from placenta, not from breathing".

Explanation:

In order to get the oxygen we need to live is necessary that the blood gets through our lungs. If an unborn baby has a problem that does not allow her to get blood to her lungs, she is still able to survive because she could get her oxygen from placenta, not from breathing. Placenta has a respiratory function that allows the baby for fetal oxygen supply and fetal carbon dioxide removal.

The right answer is B.

The purpose of breathing is to do homeostasis, which means, to take CO2 out and get oxygen to our blood.

Babies live into the wound surrounded by liquid, so they don't need to breathe with their lungs.

All the things they needed to survive are taken from the mother thought the placenta.

Answer:

Option D, telophase

Explanation:

Telophase is the last stage of mitosis cell division in which the duplicated genetic material gets arranged into two identical daughter cells. In generals, this phase begins once the replicated, paired chromosomes have separated and arranged themselves on two opposite sides, or poles of the cells. After this, nuclear envelope begins to form around the chromosomes. After telophase, the cell undergoes cytokinesis to divide the cytoplasm of the parental cell into two daughter cells.

Hence, option D is correct
