Nothing
Explanation:
Mass of the sample = 500g
Decay rate per anum = 11%
Unknown:
Mass of sample remaining after 10yrs = ?
Solution:
This is a simple percentages problem;
The radioactive sample loses 
x 500g of sample per year;
this is a loss of 55g per year;
In 10years time, the sample would have lost 10 x 55g = 550g of element.
Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.

Answer:
Cells organized into tissues
Explanation:
cells in complex multicellular organisms like people are organized into tissues, groups of similar cells that work together on a specific task
The answer is four bonds because they can use one electron for each bond.
Hope that helped :)
N2(g) + 3H2(g) <--> 2NH3(g)
Bear in mind that this is a reversible reaction.
The study of the flow of energy and its transformations is called thermodynamics.
Hope this helped!
