In the tundra, where both reindeer and wolves live, the number of reindeer herds do not
exceed the carrying capacity of their environment. in 1944, the united states coast guard ..
transported 29 reindeer to st. matthew island in the bering strait. st. matthew island has the
typical climate for a tundra, but no wolves live there.
the graph shown in figure 2 represents the growth curve for the reindeer population there.

reindeer population's growth on st. matthew island
10. by how many times did the reindeer population increase between 1945 and 1963?
11. by how many times did the reindeer population decrease between 1963 and 1966?
12. did the reindeer exceed the carrying capacity of their environment? explain your answer.
13. why do you think the population increased so rapidly in less than 20 years?
14. why do you think that the population declined so rapidly, from 6000 to 42. in 3 years?
.
15. what do you think would have happened if wolves had been brought to the island?

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
