For example, if I want to earn the equivalent of $30 per hour for a 40 hour work week, but I can only bill 20 hours, I have to bill $60 per hour. I am still working 40 hours per week, but only 50% can be billed to a client so my billable rate doubles.

Tropisms and Nastic Movements. Tropisms are growth responses of plants that result in curvatures of plant organs toward or away from certain stimuli. Tropisms can be positive, in which case the plant will bend toward a stimulus, or negative, in which case the plant will bend away from a stimulus. Important tropisms in plants include phototropism, gravitropism, and thigmotropism.
