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?

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

we need additional information in order to determine the cause of death for anna garcia. there are at least 3 things with explanation included as to why we need them are as follows:

the  different  of  these  two  are  that  they  differently  handle  their  team.

an  expressive  leader  focuses  on  the  task  at  hand  and  make  sures  that  their  goal  is  achieved.  they  accurately  finish  the  task.  an  instrumental  leader  on  the  other  hand  works  on  the  unity  of  the  group,  they  care  more  about  their  employees.  all  the  while  creating  a  good  environment.
