Find the distance from point $a$ to $\overleftrightarrow{xz}$ . round your answer to the nearest tenth. triangle x z a and line x z are plotted on a coordinate plane. the x-axis ranges from negative 5 to 5, in increments of 1. the y-axis is ranges from negative 5 to 5, in increments of 1. point x is at ordered pair negative 4 comma negative 3, point y is at ordered pair 2 comma negative 1.5, point a is at ordered pair 3 comma 3 and point z is at ordered pair 4 comma negative 1. angle a z x is marked with a right angle. the distance is about a units.

correct answer:

a + bi

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.  

hi! i think the answer is 1/2 : )
