Could emigration or immigration have played a major role in determining the size of the reindeer population? Explain. Think about where these reindeer were and whether they could swim that far

Yes.

Explanation:

Yes, emigration or immigration have played a major role in determining the size of the reindeer  population in specific area because immigration is done by the animals in search of food. The animals moves from one region to another in search of food so due to this movement the population of reindeer decreases in that specific area. Reindeer are good swimmers so due to this ability they cross the vast Yukon River which is half mile wide.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
