Two species of flies, Drosophila melanogaster and Drosophila simulans, can mate. They usually do not mate, however, even if they are kept together in a laboratory. Males court the females of both species, but the females prefer to mate with males of their own species. Which isolating mechanism does this describe? behavioral
temporal
artificial
anatomical

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

14.29%

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
