Given
QRS is an isosceles A.
RS =
SM
QS
QR

(A)∠Q=∠R

Step-by-step explanation:

Given: It is given that QRS is an isosceles triangle .

To find: The measure of the angle Q.

Solution:  It is given that QRS is an isosceles triangle .

Now, As the two sides are equal in an isosceles triangle, therefore QS=RS.

Also, ∠Q=∠R as these are the angles made on the equal sides, and we know that the angles made on equal sides are always equal in measure, therefore the measure of the angle Q will be equal to the measure of the angle R.

this, Option A is correct. Have a Awesome Day!

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.
