1) The wind (the prevailing wind)
2) The sea takes a lot longer to warm up than the land and so does not get to its warmest until late autumn in the UK, once it has had the entire summer to get warmer. However, once the sea does warm it it stays warm for a lot longer than the land does as the land losses heat a lot more quickly. This means that in the winter when the land has lost its heat the sea is still warm and so warms the land it is in contact with (not just the very edges, quite far into the landmass is warmed even if only slightly). As the UK is an island a high proportion of its landmass is located fairly close to the sea so will be warmed during the winter. This causes the UK to be slightly warmer in the winter than countries which are not surrounded by water as the land of these countries will lose heat just as fast but not be warmed by the seas retained heat.<span />
The answer is C.
Hershey and Chase did an experiment to determine whether it was the protein or the DNA that was the transformation principle in viruses by infecting bacteria cells with a virus.
They tagged the protein shell and the DNA and introduced them into a culture of bacteria cells. They concluded that it was DNA that entered the bacteria cells and not the protein.
Again the answer is C.
To understand the global systems and the changes they undergo in a better way, we can use a model to represent the various ecological processes that occur within the biosphere. One example of a model that we can use is the earth systems model.
