The answer is commensalism.
<span>Commensalism is a relationship between two organisms in which only

What are the four steps that explain how traits in a population change over time?
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
Power = I^2(current) x R (resistance)
P = 1^2 amp x .2 ohms = .2 watts
