To study whether an olfactory receptor neuron is activated by pyradine a researcher employs an imaging technique that utilizes a chemical indicator that glows green when exposed to ultraviolet light. if a decrease in the intensity of glow observed corresponds to an increase in ionic concentration in the olfactory receptor neuron in response to an odorant, which ion would this indicator chelate? choose 1 a. potassiumb. sodiumc. chlorided. calcium

Ais a landform that is formed at the mouth of a river from the deposition of sediment carried by the river as the water flows.

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
