Are marginal cost curves are identical to supply curves?

Question

Are marginal cost curves are identical to supply curves? Just yes or no with a short explanation as to why identical or not

Answer 1

yes, A supply curve tells us the quantity that will be produced at each price, and that is what the firm's marginal cost curve tells us. The firm's supply curve in the short run is its marginal cost curve for prices above the average variable cost. At prices below average variable cost, the firm's output drops to zero
