George washington gale ferris, jr., designed the original ferris wheel for the 1893 world’s columbian exposition in chicago, illinois. the wheel had 36 equally spaced cars each the size of a school bus. the distance between adjacent cars was approximately 22 feet. determine the diameter of the wheel to the nearest foot.

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.  

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
