Answer:
The correct answer would be - 9 hours.
Explanation:
The half life of a drug is the time that is required to decrease or reduced to one half of the its original achieved level or the highest amount previously taken. The half life of drug is also known as the time a drug take to complete its action.
At a dose of 500 mg the Fluoxitine drug would be 250 mg in 3 hour as it is given that half life of this drug is 3 hours, 125 mg in 6 hours, and in the end 62.5 mg in 9 hours.
Thus, the correct answer is : 9 hours.
The correct answer is B. Isotopes
Explanation:
Chemical elements are defined according to their proton number (particles positively charged), for example, in hydrogen, the atomic number is 1. Also, atoms of the same element usually have the same number of electrons (particles negatively charged) if the atom is neutral.
However, atoms of the same element can differ in the number of neutrons and therefore there are atoms with the same number of protons and electrons but not the same number of neutrons, these are known as isotopes. This variety in neutrons affects the properties of the atom such as reactivity. For example, hydrogen has three isotopes: tritium, deuterium, and protium and form this tritium is the more radioactive.
