During meiosis crossing over occurs at the pachytene stage, when homologous chromosomes are completely paired. At diplotene, when homologs separate, the sites of crossing over become visible as chiasmata, which hold the two homologs of a bivalent tighter until segregation at anaphase.
Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.

Answer:
1. Can bacteria affect any cell? How does it target?
Bacteria are much larger than viruses, and they are too large to be taken up by receptor-mediated endocytosis. Instead, they enter host cells through phagocytosis. Phagocytosis of bacteria is a normal function of macrophages. They patrol the tissues of the body and ingest and destroy unwanted microbes.
2. What causes the damage to your tissues?
When the body sustains damage from trauma, disease or simple wear and tear, it normally results in the formation of a lesion or cartilage gap on your joint surface.
