Question 3(Multiple Choice Worth 3 points) (6.03)
What is the coefficient of the variable in the expression 2 - 5x - 4 + 8?

1. -5
2. O-4
3. 02
4. 08

-5

Step-by-step explanation:

The coefficient is the number that goes in front of the variable

The only variable is x and the number in front is -5

The coefficient is -5

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.
