Guida verificata passo dopo passo1
Identify the role of each element listed in the context of biological functions related to bones and teeth.
Recall that potassium, sodium, and iron have important biological roles but are not primarily involved in strengthening bones or preventing tooth decay.
Understand that fluorine, in the form of fluoride ions, is known to stabilize bones and make teeth resistant to decay by strengthening the enamel.
Recognize that fluoride ions replace hydroxide ions in the hydroxyapatite structure of teeth, forming fluorapatite, which is more resistant to acid attack.
Conclude that among the given options, fluorine is the element responsible for stabilizing bones and making teeth resistant to decay.
