Scream Mountain's train of cars will pick up speed by gaining kinetic energy from a large hill. The cars will then rocket through three loops in the track, starting with a heart-stopping loop 180 feet high, another loop 90 feet high, and culminating in a loop 60 feet high. In simplest terms, what is the ratio of the heights of the three loops the cars will make? HINT: As with a ratio with two items, line up the quantities and separate them with colons. Then simplify.

think about it deeply and passionately about this property

i am sorry

homozygous. one is homozygous, while two is heterozygous.

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'm not really sure how to answer that
