A scientific theory. Obviously, the hypothesis would need a considerable amount of increased testing to be proven a scientific law. But, even so, it could become a theory.

I hope this helped you!

What is the difference between the ligamentum arteriosum and the ductus arteriosus?

Goshia [24]

In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.

The magnets point North when the Earth's magnetic field has (p2)<br><br>need some help :)

<h2><u>EARTH'S MAGNETIC FIELD</u></h2>

The magnets point North when the Earth's magnetic field has?

<h2><u>ANSWER</u></h2>

I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.

In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.

<h2><u>THE MAGNETIC REVERSAL</u></h2>

The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.
