In nuclear medicine, a radioactive isotope, or tracer, can target a particular organ to take a "picture of it. Which properties of the tracer make it useful in nuclear medicine?

Check all that apply.

The isotope should have a short half-life.

The half-life of the tracer should be long in duration

The tracer should have the ability to damage tissues

A (the first option) and C (the third option)

Explanation:

The isotope should have the same behavior as other isotopes of the element.

and

The tracer should have the ability to be metabolized and excreted from the body.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

is there any options? maybe im just not seeing them but i need the options to
