chemical change- it is a change in matter that alter its chemical and thus its physical properties. Most chemical changes are irreversible. for example- burning of paper, results in black soot and ashes- Thus changing both physical and chemical properties.

Answer: Resistance
Explanation:
Bacteria are single cell microbes that can be found in plant cells, animal, human body...They could be beneficial some are use for fermentation or harmful.
Over time, Bacterial have shown resistance and virulent to man by gaining resistance to antibiotics use to destroy there adverse effect in human system.
Some bacteria such as mycobacterium gonorrhoeae that causes gonorrhoea has shown medium resistance to antibiotics
Acinetobacter Baumannii causing pneumonia has shown a high level of resistance towards antibiotics making it difficult to reduce there effect. This has lead to more research on how this bacterial will be less virulent and harmful to man
