Tepper, B.J. Actin and myosin allow muscles to contract, while albumin nourishes the early development of an embryo or a seedling. A vertical asymptote represents dividing by 0, which is not possible, hence the function is not differentiable at (0,0) Upvote 0 . Dose-response functions and methodological insights for sensory tests with astringent stimuli. Enzymes are another type of protein, and these molecules catalyze the biochemical reactions that occur in cells. Protein is an important nutrient for optimal health, but not all protein sources are equal. Asked 4/16/2019 2:18:52 AM. The relation (option d) represents a function.
