Syke Under Shield $ millions Current Year 1 Year prior Current Year 1 Year prior
Net income $ 3,107 $ 3,408 $ 981 $ 2,092

Total assets 18,611 23,494 15,982 28,656

1. Compute the return on total assets for the current year for (a) Syke and (b) Under Shield.

For Skye - 15.85%

For under shield - 5%

Skye is using its asset more efficiently because its ROA is higher

Step-by-step explanation:

Return on total assets =  Net income / Average total assets

For Skye

$3192 /  [(18,764 + 21,512)/2] = 0.1585 = 15.85%

For under shield

$ 649 / [(10,252 + 15,659)/ 2] = 0.05 = 5%

Skye is using its asset more efficiently because its ROA is higher

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

hello! just here for points! though i wish i knew!
