Brief Explanations:

In a competitive market, an individual - firm's supply curve is its marginal cost curve above the average variable cost curve. This is because the firm will produce and supply output as long as the price is at least equal to the marginal cost to maximize profit. The total market supply curve is the sum - of individual supply curves. Technological progress may shift the supply curve but is not the reason for its positive slope. Under perfect competition, an individual firm's supply curve is upward - sloping above the AVC, not horizontal.

Answer:

the same as the individual's marginal cost curve
