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.
<u>Answer:</u>
<em>Ocean water is sinking at the North Atlantic Buoy Station the given things have occurred.</em>
<u>Explanation:</u>
The way of thermohaline course starts at high scopes, where cold seawater sinks due to its generally high thickness.
In the Northern Hemisphere, profound sinking to 2000-3000 meters happens just in the North Atlantic, not in the North Pacific on the grounds that the waters of the North Pacific are freezing and not as salty as the waters of the North Atlantic.
In this way, Earth's profound sea bowls are loaded up with waters from the northern North Atlantic and those that sink close to Antarctica.
Answer:
B) binding of a molecule to a binding site affects the binding properties of another site on the protein.
Explanation:
In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.
