This question is unfortunately incomplete. This question relates to the advantage derived by some parasites by maintaining a low level of infection in the host. These parasites achieve this by a gene for its surface glycoproteins that is duplicated thousands of times, with each gene coding for a slightly different glycoprotein structure. By constantly shifting between glycoproteins of different structures, the parasite can fool the host into temporarily reversing the immune response. The question includes a table showing the change in parasite blood concentration with time, with the table showing distinct waves of increases in parasite concentration followed by decreases. Using the hypothesis about changing glycoprotein structure, it makes sense that the host begins an immune response, leading to a decrease in parasite numbers, at which point the parasite changes the structure of its surface glycoproteins, thereby allowing the parasite to overcome the immune response, and the concentrations of parasites increase once again.
Answer:
do it in your self hahahahahaa
Esto es debido a que en los lugares húmedos las plantas absorven el agua con las hojas y no necesitan hacer crecer la raíz para buscar agua. En cambio, las plantas que viven en lugares calurosos necesitan agua por lo que expanden las raíces hacia abajo para poder encontrar líquido e hidratarse.
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 />
