Answer:
2.62 years
Explanation:
The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.
If a radioactive material is cut into pieces, each piece has the same half life as the whole material.
Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.

Answer:
There are many ways that classes of people differentiate themselves from others, but one of the most common ways is by race and/or community where there is a plurality of people.

The main difference in the process of waste removal between unicellular and multicellular organisms is the fact that unicellular organisms rely on only their membrane and organelles, the whole process is in inside the cytoplasm of the cell and once waste is formed, it is "packed" in special sacs called vacuoles and then, through the process of exocytosis they are being left out of the cell. On the other hand, multicellular organisms most often have specific organs that are in charge of the process of digestion, absorption and excretion or removal of waste.
