Suppose two populations of Anolis lizards are of equal size at the beginning of an experiment. One population (the experimental group) is exposed to a predator (16 predatory lizards), and the other (the control) is not. The final size of the experimental population is 50, and the final size of the control population is 200. What is the per capita interaction strength of predatory lizards on Anolis lizards

Per capita interaction strength is -0.046875.

Explanation:

N=50, D=200, Y=16, interaction strength is  estimated as (N-D)/(DY)

(50-200)/(200*16)= -0.046875

The correct answer is option C, Scientists argue, re-examine, and consider new explanations to new data.

Explanation:

Science is a subject which is learned through continuous assessment.  

All the established scientific theories are considered as the best explanation to any concept or fact. These established theories were also tested several times and were supported by peers during the time of their discovery. But yet the scientific theories changes as theories need to be progressive. Which means they must be embedded with scope of re framing itself in future if some better explanation for the same theory is found.  

Science is however, a continuous process of learning.
