Regarding the relationship between a human and host and their microbiome, which of the following statements are true? SELECT ALL THAT APPLY Antibiotic usage has little effect on the microbiome and only kills pathogenic microbes. The relationship between the host and members of the microbiome is considered a symbiotic relationship. Because of all the deadly infections associated with it, it is always dangerous to have Escherichia coli living on the surface of your intestine. Once the microbiome is established early in life it remains generally constant throughout life (unless there is an extreme change in health) In some circumstances, the relationship between the host and the microbiome could be considered parasitism.

Please select true statements about the microbiome from the options below (please select all correct responses): - It exists due to an agreement millions of years ago between our bodies and the microbial environment we are surrounded by. - In exchange for shelter and food, the microbiome works for us. - Delivery via the birth canal helps the microbiome get started in infants and helps with immune function. - It takes until age two for a person's microbiome to be ready to protect against illness. - There are special sugars within breast milk that nourish the developing microbiome - these elements are not digestible by the baby, but are perfect for the microbiome. - The food we eat changes the composition of our microbiome. - Antibiotics can be very harmful to our microbiome. - The relationship we have with our microbiome is symbiotic. - All of our neurotransmitters are produced in the gut/microbiome.

Which of the following statements accurately describe research into the human microbiome? Select all that apply: - It has expanded rapidly during the megasequencing era. - It has found that most microbes are commensals that neither benefit nor harm the human host. - It has led to the development of new culture techniques. - Its importance became clear as a result of successful efforts to culture large numbers of microbes. 9. Smoking damages cilia that line the respiratory tract, and this means that __________. Select all that apply: - The risk of respiratory infections is higher. - Microbes can more easily reach the lower lungs and stay there without being expelled quickly. - Microbes are moved out of the respiratory passages too quickly. - There is no normal microbiota in the lower lungs because the microbes cannot survive.
