Incubating and viewing plates. Incubating the plates to promote growth of microbes is an essential part of any microbiology investigation.

Sperm are very tiny and resilient things! So all it takes is a small hole (where the tube was tied and burned) for them to get through and if you've ovulated, then the sperm can fertilize the egg. But the reason so many of these pregnancies are ectopic is because the fertilized egg starts to grow and cells divide. So then it can't fit back through the tiny hole the sperm was able to slip through. So the fertilized egg/cells implants wherever it's able, which can be on either end of the cut/burnt Fallopian tube.
