What is the carrying capacity?
The mathematical term for the number of ways to arrange a set of objects.

This measure of spread is found by taking the square root of variance.
What is the standard deviation?
In computer science, "Big O" notation describes this property of an algorithm.
What is time complexity?
This process describes the movement of water across a selectively permeable membrane.
What is osmosis?
