Males are easily distinguished from females based on colour differences, with a distinct black patch at the abdomen, less noticeable in recently emerged flies (see fig.), and the sexcombs (a row of dark bristles on the tarsus of the first leg).
total asset turnover. A financial ratio that indicates the effectiveness with which a firm's management uses its assets to generate sales. A relatively high ratio tends to reflect intensive use of assets. Total asset turnover is calculated by dividing the firm's annual sales by its total assets.
Average total assets = (100+120)/2 = $110, sales are $200 so total asset turnover is $200/$110 = 1.82. If the industry average total asset turnover ratio is 1.2 we can conclude that the company has used its asset more effectively in generating revenue.
