What is one major difference between the attributes of mercury and jupiter

C.  

Mercury has no orbiting satellites, while Jupiter has many satellites circling it.(even though mercury now does have a satellite now called MESSENGER!)

but C. is your answer if C. is the one with "Mercury has no orbiting satellites, while Jupiter has many satellites circling it."

the median of the data is 4.5.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
