Ahemoglobin molecule can bind 4 o2molecules. assume that e is the energy of each bound o2 relative to o, at rest at infinite distance. let λ denote the absolute activity exp(u/kt) of the free o2 (in solution). a) write the partition function for this odel. b) what is the probability that one and one only o is adsorbed on a hemoglobin molecule? c) what is tbe probability that three and only three o are adsorbed?

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

Ibelieve the answer is d. macula  hope my answer has you : )
