When they come to the ground, it is lightning.
Answer:
Viruses today are not considered living things, since a comparison of archaeobacteria and living things in general cannot have autonomous reproduction methods, if they need to be replicated in a DNA or RNA replication medium foreign to them.
This means that their DNA or RNA cannot replicate by itself, that is why they need to be detected in cells or bacteria (forming bacteriophages) in order to assemble in the DNA of these living beings and replicate in a "hidden" way.
Explanation:
There are cells that recognize the invasion of certain viruses so they self-destruct and do not allow replication of it in the replication of their own DNA, RNA, but there are others that do not, that is why there are viral diseases such as HIV.
On the other hand, in the case of bacteria, they form bacteriophages or form mutations in the DNA, RNA of these living prokaryotic organisms, resulting in more pathogenic or potentially dangerous microorganisms.
The CNS are lined by ependymal cells. Ependymal cells are epithelial cells that monitor the composition of cerebrospinal fluid (CSF)
