Answer:
The best answer to the question: If the ice in Antartica melted, the sea level would rise about:___, would be: 200 feet.
Explanation:
According to research and data found, the possibility of either of the poles completely melting off is practically nil. The planet has not gone through just one, but several ocassions in which temperatures in the atmosphere have risen due to greenhouse gases, but in all of them, after a period of time, the balance was restored. And in none of those ocassions, did the poles melt completely. In fact, according to several geologists whose research has been published, the Earth has natural mechanisms of defense that would not permit such a thing to happen. However, some of them have asked themselves the hypothetical question of what would happen, especially to sea levels, if just one of the two poles, Antartica, melted, and the answers they have gotten have been: they would rise over 200 feet, and they would most likely cause coastal cities, and various islands, to disappear under water.
The reason why one case of influenza does not confer lifelong immunity is that the virus tends to mutate overtime which makes it unrecognizable to the immune system.
<h3>Why is it difficult to get immunity to influenza?</h3>
Influenza is caused by a virus which tends to mutate overtime in order to stay ahead of medical technology.
As a result, this mutation makes the original virus unrecognizable to the immune system which would then be unable to fight it.
