I know probabilities is to calculate the liklihood of an event. Is this also used to mathematically record the actual occurance of the event, and creating a math pattern of the event over time?

Ugh im so confused and its because i take things word for word in the textbook.

'The force of air ressitance acting on an accelerating falling body increases, until it balances the force due to its weight. At this point the object falls at its terminal velocity'

If the air resistance=force due to weight wouldnt he NOT be falling then ??

To determine the rate of DNA synthesis in cells, you can provide them with a radioactive nucleotide and watch the rate at which the cells add the radioactive nucleotide into DNA. To most accurately find the rate of DNA synthesis, which nucleotide should you use - A,T,C,G,or U (uracil)? Why?
