Write your answer with no space and any fraction with “/“

y + 3 = -½(x - 1)

Step-by-step explanation:

Point-slope form equation is given as y - b = m(x - a), where,

m = slope, and (a, b) is a point the line passes through.

Given that the line is perpendicular to the y = 2x - 1, the slope (m) will be the negative reciprocal of 2, which is -½.

Thus, substitute m = -½, a = 1, and b = -3 into y - b = m(x - a).

Thus:

y - (-3) = -½(x - 1)

y + 3 = -½(x - 1)

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.
