Question

how microorganisms protect them from harsh conditions what is the name of shield they use in that time​

Answer 1

Answer:

Some organisms have developed strategies that allow them to survive harsh conditions. Almost all prokaryotes have a cell wall, a protective structure that allows them to survive in both hypertonic and hypotonic aqueous conditions

Explanation:

Bacteria can defend themselves against infection by bacteriophages using an adaptive immune system called CRISPR-Cas. This prevents the phage from evolving mutations that would normally allow them to overcome a single spacer, leading to phage extinction. However, anti-CRISPR genes on phage genomes can change this.

Answer 2

Plasma membrane protects the microorganisms
