Alexander litvinenko was poisoned with 10 micrograms of the radioactive substance polonium-210. since radioactive decay follows a compounded continuously model, we can determine the amount of substance left in alexander litvinenko's body at any given time. if polonium-210 has a decay rate of .502%, then determine the amount of polonium-210 left in his body after 115 days. provide 3 decimal places and a label in your answer.

Left amount of Polonium-210 after 115 days will be 4.5927 microgram

Explanation:

We have given initial mass of Polonium-210

Decay rate x= 0.502% = 0.00502

Time t = 115 days

We have to find the left amount of Polonium -210 after 115 days

We know that left amount is given by

So left amount of Polonium-210 after 115 days will be 4.5927 microgram

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
