Do bacteria have brains?

Do bacteria have life?
Bacteria don’t have a fixed lifespan because they don’t grow old. But if we assume that the global bacteria population is stable, then it follows that one bacterium must die for each new one that is produced. Bacteria divide somewhere between once every 12 minutes and once every 24 hours.
What are bacteria made of?
Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA.
Can bacteria hear?
Bassler and her colleagues have examined the molecule in atomic detail and seen what it looks like when it is clasped by its appropriate sensory protein—the “ear” that allows bacterial cells to hear the molecule’s cry.
Is bacteria the same as a virus?
On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.

What are the types of heart infections?
Types of Heart Infections. Several of the most common types of heart infections include endocarditis, which is an infection of the lining of the heart, or of heart valves inside the heart. In most cases, endocarditis is caused by bacteria. Another heart infection, called pericarditis, is an infection of the sac that surrounds and cushions the heart,…
