biology!!!?
A certain bacteria is capable of reproducing by binary fission once every half hour. Suppose you placed a single bacteria in an enviroment where it would reproduce at this rate. How many bacteria would be present after 3 hours? After 12 hours? What factor might limit how long this rate of reproduction could continue?
I don’t get this question!! Can someone help me!!! ( Thanks)

It’s mostly a math question in its essence. These throw me off when they show up in Algebra because they’re science, and vise versa…. An exponential expression thingy. I think. But here’s how to do them. Or, actually, this specific one, but it’s the same principle:
after 3 hours there would be 64 bacteria. it doubles every half hour. 3 hours = 6 1/2 hours. so 2^6 = 64.
after 12 hours there would be 16,777,216 bacteria. 12 hours = 24 1/2 hours. 2^24 = 16,777,216.
Limiting factors could include inhospitable temperatures, insufficient food or space in which to grow.
Every half hour the population of bacteria doubles, the math is simple you can do it. The two big limiting factory on bacterial growth are always food and space.
3 hours = 64 bacteria
12 hours = 16777216 bacteria
