Protosomes and Deuterosomes
What are key characteristics of protosomes?
spiral cleavage in embryo, there is a determinate cleavage when cell lineages become functionally specialized, the coelom forms with schizoceolous patterns, mouth

One challenge people face is the presence of antibioticresistant bacteria. Antibiotics are used to treat many diseases. Generally, they improve the quality of life of people. However, the widespread use and misuse of antibiotics has created antibiotic-resistant bacteria. This means that some diseases caused by bacteria no longer can be cured with the same antibiotics. Doctors must use new and stronger antibiotics to cure the disease. This gives bacteria an opportunity to develop a resistance to the new antibiotics. Unfortunately, antibiotic resistance in bacteria is spreading faster than new antibiotics are being developed. Evaluate how the characteristics of bacteria contribute to the rapid development of antibiotic-resistant bacteria.
