Achange in the water level of a swimming pool is recorded as $-12$ inches.

which of the following statements must be true?

select all that apply.

a the water level increased by $12$ inches.

b the water level increased by $\abs{-12}$ inches.

c the water level decreased by $\abs{-12}$ inches.

d the water level has a height of $-12$ inches.

e the water level experienced a change of $12$ inches.

True statements are:

C. The water level decreased by \abs{-12} inches.

E. The water level experienced a change of 12 inches.

Step-by-step explanation:

A change in the water level of a swimming pool is recorded a -12 inches.

Now, from the above statements, we have to choose options statements that are true.

A. The water level increased by 12 inches. This is false.

B. The water level increased by \abs{-12} inches. This is also false.

C. The water level decreased by \abs{-12} inches. This is a true statement.

D. The water level has a height of -12 inches. This is again a false statement.

E. The water level experienced a change of 12 inches. This is a true statement. (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.
