I believe the answer is the B-cell
These are types of lymphocyte derived from the bone marrow and provides the humoral immunity. They produce antibodies; which are proteins that sticks to pathogen preventing them from sticking to cells and flagging them for destruction. The primary role of the B-cells is to make antibodies in large amounts and assist in destroying foreign agents through role as APC.
Isotopes are atoms of the same element with the same atomic number but different mass number. unstable atoms atoms undergoes radioactive decay. Therefore radioactive decay is the process by which unstable nucleus loss energy by emitting radiations such as beta , alpha and gamma particles.
The initial mass of radium-226 is 6 grams and the new mass is 0.375 grams therefore the number of half lives undergone are 0.375 = 6× (1/2)n where n is the number of half lives. (1/2) n = 1/16
therefore n= 4. Meaning the isotope radium-226 has undergone 4 half lives
1 Half life = 1600 years
4 half lives = 1600 years × 4 = 6400 years
therefore, the rock reached its closure temperature 6400 years ago and secondly when the rock was discovered it had 5.625 g mass of radon-222.
