The scientists are interested in bubbles of atmosphere trapped in the ice cores. By the depth of the ice, they have some idea of the age of the atmospheric bubbles. By the composition of gasses in the trapped air, they can determine the proportions of atmosphere made from the composite gasses: nitrogen, oxygen and carbon dioxide and a few other gasses. This is how scientists have determined that the proportion of carbon dioxide has increased in our atmosphere since the Industrial Revolution.

Flood is the overflow of water on the land which is usually dry throughout the year. It occurs when more water comes in the river due to rainfall or breaking of dam. But mostly flood occurs, due to melting of ice on the poles because of global warming.

Describe how cooperativity of oxygen binding in hemoglobin is advantageous for the transport of oxygen from the lungs to the tis
Nostrana [21]
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.
