Ductus Arteriosus is a blood vessel normally present in fetuses during development. The blood vessel is designed to bypass the pulmonary artery and brings blood to the Descending Aorta, as the fetus cannot breath through the lung (being as they are fluid filled). This is normally not a problem because oxygenated blood comes from the mother's blood supply.
Patent Ductus Arteriosus, is what happens when that vessel does not close. While not as dangerous as other congenital defects. However, because there is still a bypass, blood that normally need to be oxygenated by going through the pulmonary arteries to the lungs, can be diverted and placed into the blood stream without vital oxygen. This condition may eventually lead to CHF (congestive Heart Failure) and Pulmonary Hypertension if not treated.

<span>Research partitioning is an adaptive evolution that when
species are have similar preys, they compete with each other and one species is
deemed to extinct in the process however if two species are of different preys,
then they can exist with one another. To exist with one another, organisms
belonging to a same species either compete for the resources or divide it
amongst themselves. This concept is important because it helps in diversified
ecology, where animals and plants of the same species co-exist and creates a
beauty with nature.</span>
