Survival of bacteria.. The inner spores of a latent cell resist harsh conditions. Mutations randomly change the order of genes in the chromosome

There are ways in which bacteria can survive if environmental conditions become inappropriate and harsh, such as extreme temperature change, water scarcity, etc. These include:
A. Internal spores:
* Internal spore: It is a latent cell that resists harsh conditions such as (high temperature, extreme cold, drought, ultraviolet radiation).
When the conditions improve, the spore grows into a new cell (this method is not considered a breeding method because it does not lead to a numerical increase).
B mutations:
Is a random change in the order of genes in the chromosome (DNA) resulting in new forms of genes and new traits and genetic diversity.
Genetic mutations therefore help bacteria survive in a constantly changing environment.
