you are interested in determining which of two brands of batteries, brand A and brand B, lasts longer under differing conditions of use. One hundred fenix flashlights are fitted with brand A batteries and 100 olight flashlights are fitted with brand B batteries. each battery is used for 72 hours straight. The battery life is then measured for each battery, adn the average battery life for the two brands is comprared. what is wrong with this experimental design

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

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.
