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.
If white roses and red roses are cross-bred by scientists, it would be artifical selection. If they were crossed in nature, it is called crossed pollination.
