Which expression is equivalent to

Step-by-step explanation:

Эквивалентные выражения. Два логических выражения, содержащих переменные, называются равносильными (эквивалентными), если значения этих выражений совпадают при любых значениях переменных. Так, выражения А → В и (¬А) \/ В равносильны, а А/\В и А \/ В – нет (значения выражений разные, например, при А = 1, В = 0).

i belive those are the ones that are under 90 degreese.

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.
