What is the y-intercept in the equation: y = 5x + 7

the y-intercept is 7

Step-by-step explanation:

y=mx+b

m=slope

b= y-intercept

probability for j is 1/4

while

a is 1/6

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.
