What are some benefits of Organisims in Domain Bacteria?

Question

:-)

Answer 1

1. size - since that are small they can profilerate quite easily to other organisms including plants, animals, fungi.
2. symbiotic relationships - many bacteria have symbiotic relationships with animals plants and fungi. For example some bacteria help with digestion in animals and also allow plants to absorb certain materials that plants and animals could not normally, for example certain bacteria allow cows to digest cellulose.
3. ability to multiply rapidly - because bacteria are mostly prokaryotic they can multiple quite rapidly because there mechanism to replicate DNA is less complicated.
4. ability to adapt/evolve- bacteria have a tendency to mutate more often because there mechanisms for detecting and fixing DNA mutations are not as advanced, so when they are subjected to an environmental condition such as anti-biotic drugs for example there are likely to be strains that are resistant because of their numerous mutations.
5. MOST IMPORTANT Bacteria are the only known organisms to have a natural competency for DNA transformation. they have an ability to transfrorm DNA from dead and living organisms. For other organisms such as yeast fungi plants and animals, scientists must perform the transformation artificially

Answer 2

Well, I'll give you one example (I could write a whole book on this). Our body gives off certain chemicals that attract a certain kind of bacteria that eventually covers our entire body, but it doesn't hurt us. The good thing about this is, while this neutral bacteria is covering skin, bad bacteria can't be there.

Answer 3

They're small. High proliferation rate.
