Answer:
is a shallow depression in the interventricular septum
Explanation:
The foramen ovale is a little hole found in the tissue which separates the two upper chambers of the heart, also known as the septum. Before his/her birth, a baby does not use his/her lungs, so he/she gets oxygenated blood from his/her mother's placenta, and this is distributed using the umbilical cord. The foramen ovale then allows the blood to flow from the right to the left sides of the baby's heart.

A investment is a broker statement
Hello,
The answer is option D "<span>a diary entry from an American homemaker in 1933".
Reason:
The answer is option D because the diary of a homemaker from 1933 is the original source of a subject that people can write off of and learn about. A primary source is the original source of a subject for example of homemaking. Its not option A because a magazine summary of the history of voting is not the original version of the history of voting. Its also not option B because a blog entry about how Roosevelt is the most important president is just a opinion. Its also not option C because a book about the civil war that was written by a historian wouldn't be the original source since how he or she gets the information from other sources in order to write the book.
If you need anymore help feel free to ask me!
Hope this helps!
