The graph of an exponential model in the form y = a ⋅ bx passes through the points (2, 50) and (3, 250). Which point is also on the graph?
A. (0, 5) B. (1, 10) C. (4, 450) D. (5, 650)

We choose B. (1, 10)

Step-by-step explanation:

Given the exponential model in the form y = a

<=> 50 = a  

<=> a = (1)

<=> 250 = a (2)

Substitute (1) into (2) we have:

250 =  

<=> 50b = 250

<=> b = 5

=> a = = 2

Hence, our exponential model is: y =2*

Let analyse all possible

A. (0, 5) we have: y =2*   ≠ 5 so it is wrong

B. (1, 10) we have: y = 2* so it is true

C. (4, 450) we have: y = 2* ≠ 450 so it is wrong

D. (5, 650)  we have: y = 2* ≠ 650 so it is wrong

Hence we choose B. (1, 10)

step-by-step explanation:

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.
