Step-by-step explanation:

The constant speed formula is defined as the ratio of constant distance traveled divided by the amount of time taken to travel the respective distance. In other words, speed = distance/time. Constant speed represents how fast something moves.

answer: i don't understand it

step-by-step explanation: sorry

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.
