Typically as cells grow, their increase in volume outpaces their increase in surface area, and continued survival requires undergoing asexual reproduction to reestablish a healthy surface area to volume ratio. Thus, which of these is least likely to contribute to the ability of a single-celled foraminiferan to grow to a diameter of several centimeters?

 Following figure are shown figure of predator prey model 

Following some observation are given

A) The number of prey, N, increase at low predator densities, P, and decrease at high predator densities

B) Prey zero isoclines is depends on the ratio of the growth rate of prey to the capture efficiency of the predators

C) Number of predator needed for prey isoclines is depends on the ratio of the death rate of predators to the conversion efficiency of predators

D) Number of predator for prey isoclines depends on the ratio of the death rate of prey to the conversion efficiency of predators

Which of the above observation are true?
