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.

Explanation:
There are over 200 different cell types in the human body. Each type of cells is specialised to carry out a particular function, either solely, but usually by forming a particular tissue. Different tissues then combine and form specific organs, where the organ is like a factory where every type of cell has its own job.
Answer:
Temperature is the most harsh abiotic factor that limits distribution of the tundra biome.
Explanation:
The tundra biome can be described as a biome that is one of the most abundant biome of the earth but allows little growth of trees due to its very cold temperatures. Often, in a tundra biome, no trees would be seen. The ground soil of this biome remains frozen most of the year and is termed as permafrost. The tundra biome shows very little biodiversity due to the extreme cold conditions. Very few animals and plants are adapted to live in these conditions.
Answer:
as the human population grows, more people will on be on earth and if those people pollute in the ocean the ocean will get dirtier and unhealthy for the underwater creatures.
Answer:
People cannot travel more than a few miles beneath Earth's surface because of the intense heat and pressure.
