Rectangle abcd is congruent to rectangle . which sequence of transformations could have been used to transform rectangle abcd to produce rectangle ?
a.
rectangle abcd was rotated 90° clockwise around the origin and then translated 7 units left.

b.
rectangle abcd was rotated 90°counterclockwise around the origin and then reflected across the x-axis.

c.
rectangle abcd was rotated 90° counterclockwise around the origin and then translated 8 units down.

d.
rectangle abcd was rotated 90° clockwise around the origin and then reflected across the y-axis.

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.  

yes because they have the same amount of green and blur marbles.
