In a population, the number of red foxes changes from 20 percent to 30 percent. what can you say about that population of foxes?

a. carrying capacity has been reached.
b. the red foxes are increasing.
c. the red foxes are staying the same.
d. the red foxes are decreasing

B,  The red foxes are increasing

this is because 20 percent is higher than the 30  

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

< 3

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
