3. at the beginning of the day, a water tank contained 526.8 gallons of water. during the day,
some of the water was used to water a garden. at the end of the day, the water tank contained
318.05 gallons of water.
what was the total amount of water used that day?
a. 202.75 gallons
b. 208.75 gallons
c. 208.85 gallons
d. 210.80 gallons

Step-by-step explanation:

the total amount of water used that day = 526.80 - 318.05 = 208.75 gallons.

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.
