What is the total length of the race (from point a to point b and point b to point c

if that is the entire question then the answer should be length ac

Step-by-step explanation:

Simple

Step-by-step explanation:

We need the total distance

For that we need to add all points (point a, point b, point c)

Add point a and b point at first then add point c with the answer of point a and b.

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.  

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
