Prokaryotes have circular DNA, while the DNA found in Eukaryotes is linear. Eukaryotes are more complex microorganisms and are thought to evolve from Prokaryotes. Why did eukaryotes develop a linear structure and didn't keep the circular DNA of prokaryotes?

I wonder what glass made from Coney Island Beach sand, for example, would look like. Are the impurities such that one couldn't create a glass object with this sand?

If I were to begin walking toward an object that is 1 mile away from me and stopped half way for 1 second then resumed walking at double the speed and walked half the distance again and again dobled my speed, and continued this process for eternity, would I not eventually be walking faster than the speed of light and never reaching the object?

I already know PV=nRT, and how to calculate the gas ratios, stoichiometry of the moles of liquid --> gas, the increase in air pressure, and the (pie)(r)^2 Area of the piston. How much gasoline is squirted into each cylinder/stroke ???

from 1987 to 1997 the #'s of banks could be found by this equation, N(t) = -458t + 923,769. where "t" is the year. approx. what is the # of banks in 1987 and 1997?

do i need to find the "t" first? but how do i find that if it only gives me 1987 and 1997? do i need to subtract the years to find "t"?

thanks for the help.

By gay, of course, I mean gay in the sense that we usually apply strictly to humans, with a specific sexual attraction to members of the opposite sex within their own species.

I mean sure, we all know dogs aren't too partiuclar and will bump uglies with the nearest convenient chair leg, but does it really make sense to talk about gay animals?
