Answer:
The greatest changes to the path and strength of the Gulf Stream might be caused by an increase in the volume of river water that flows into the Gulf of Mexico (Option B)
Explanation:
The North Atlantic current or Gulf Stream carries warm water from the Gulf of Mexico forward Europe, providing a relative template clime in most of the European occident.
Ocean streams are sensitive to the amount of freshwater available on the surface. An increase in overflow and precipitation over the ocean could slow or revert the north Atlantic current, blocking warm water flow to Europe.
The deposition of freshwater could cause a temporal deceleration or total collapse of the North Atlantic Current, and this interruption might lead to very cold periods in the North Atlantic.
What are the two primary sources of energy for the earth
The affinity of hemoglobin for oxygen is less than its structural analog myoglobin. However, this does not affect hemoglobin's usefulness for the body; on the contrary, it allows hemoglobin to be a more efficient carrier than myoglobin. This is because hemoglobin can release oxygen more easily than can myoglobin. It is both important for oxygen to be carried to different areas and also to be released when needed. The higher affinity of a given protein for oxygen, the harder it will be for that protein to release oxygen when needed. Therefore, hemoglobin's lower affinity for oxygen serves it well because it allows hemoglobin to release oxygen more easily in the body.
