A figure is graphed in the coordinate plane. Which pair of transformations will NOT preserve the size and the shape of the figure?
A. Rotate the figure 180° counter-clockwise about the origin and then reflect it over the y -axis
B. Reflect the figure over the line y = x and then translate it 2 units up
O
C. Translate the figure 3 units to the left and then dilate by a scale factor of 4
O
D. Rotate 90° counterclockwise and then dilate by a scale factor of 1

a is the right answer

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.  

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
