To create a simulation of 100,000 ants moving around inside a colony, a scientist needs to determine the average traveling speed for an actual ant. which of the following is the best course of action for establishing this parameter?
a. divide the total distance traveled by 100,000 ants in a day by 24 hours.
b. determine the average traveling speed for 20 randomly selected ants.
c. choose a random value to represent the average traveling speed of an ant.
d. measure the traveling speed of a single ant, and assume all ants are the same.

1. variations in a population of moths allow for some of its members to be able to adapt to environmental changes. the better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) describe three mechanisms in which variation can occur within a species population. (b) explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. justify your answer.
