(7th grade) please help!!

Step-by-step explanation:

26) abs(10)=10

The absolute value of a positive number equals to that positive number. It cannot be a negative number. Therefore, the statement is false.

27)  abs(-5)<4

abs(-5)=5>4

The absolute value of a negative number equals to that number as positive, therefore, 5 is bigger/larger than 4, which makes the statement false.

Please mark me as Brainliest if you're satisfied with the answer.

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.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
