So, baby and placenta are both inside the uterus, with the placenta off to the the side inside and the baby or fetus or embryo also inside the uterus but at the center and up against the other side of the womb. The fertilized egg is the zygote.
Like many living things, viruses live to reproduce. They find a host cell, replicate themselves, and leave the host cell with all of their new copies. One method of reproducing and fleeing a cell is the lytic cycle. In a lytic cycle, the virus reproduces thousands to millions of times in just a few hours, then weakens the cell wall enough that the cell will lyse, or burst open, setting the army of new viruses free.
The key difference between the lytic cycle and the lysogenic cycle is that the lysogenic cycle does not lyse the host cell. Phages that replicate only via the lytic cycle are known as virulent phages while phages that replicate using both lytic and lysogenic cycles are known as temperate phages.emperate phages (such as lambda phage) can reproduce using both the lytic and the lysogenic cycle. Via the lysogenic cycle, the bacteriophage's genome is not expressed and is instead integrated into the bacteria's genome to form the prophage.
