Archaea and bacteria are closely related because they are both prokaryotes 

Bacteria are genetically most diverse on earth 

Their protein are more similar to human proteins 

Archaea protein are more similarly to human, their DNA share some similarities with human DNA,

Bacteria and Archea are look alike but they are different in many ways.

The bacteria are most diverse things 

Eukaryotes contain nucleus 

Archea prokaryotes are just one cell Prokaryotes 

Eukaryotes some of them are single cellular and multicellular 

Human are many cell 

There is a structure cell cell nucleus contains DNA

Virus are typically not cell 

Virus is super tiny 

symbionts-providing benefits e.g yoghurt 

Pathogens-causing harm disease 

Good bacteria are protect your skin prevent from infection 

Some microbes live in relationship with other organisms.

Mutualism means both organisms benefit 

Commensalism’s means one benefit and other is not harm.

Why bacteria and archea living 

They use different type of energy 

The way we get energy 

The way we grow we eat the energy compounds 

To eat organic compound to build molecules 

There are some microbes are so wired they used inorganic compounds e.g iron or magnesium 

Many can take carbon dioxide to build their molecules 

Food yoghurt kimchi Cheese good for micro biome 

Yeast to produce insulin 

Yeast produce beer 

Microbiome have to fight off the pathogens 

They are in the guts 

Healthy microbiome  

Less healthy gut related to mood swings conditions 

Microbes in the mouth help you to digest 

Microbe help the regulation of PH 

Eating yoghurt and kimchi help your micro biome healthy

In the mouth blue bacteria colonies
