Radon and Thoron are the most significant sources of radiation exposure to people living in the United States accounting for 37% of total radiation exposure.
These are nuclides that are produced from the radioactive decay of materials especially in consumer products and through natural processes such as the decay of radium.
Answer:
Population A has 4590 and population B has 1520 bacteria
Explanation:
Let’s mark bacteria:
a - bacteria from population A
b - bacteria from population B
Every bacteria <em>a</em> needs 4 units of the first nutrient and every bacteria <em>b</em> needs 1 unit of the same nutrient, so we can write it down as:
4*a + 1*b = 19880
Let’s do the same for the second nutrient. Every bacteria <em>a</em> needs 5 units of the second nutrient and every bacteria <em>b</em> needs 6 units of the second nutrient:
5*a + 6*b = 32070
Now there are two equations and two unknowns. From the first equation, we can separate <em>b</em>:
b = 19880 - 4a
Let’s place this <em>b</em> to the second equation:
5a + 6*(19880 - 4a) = 32070
5a + 119280 - 24a = 32070
119280 - 32070 = 24a - 5a
19a = 87210
a = 4590
This can be brought back to: b = 19880 - 4a
b = 1520

Explanation:
The canned food are packed with special packaging material to make the food item freshness last longer. The food items are preserved in tin packs with airtight packaging.
During this stage The cell would still be considered a diploid. meiosis involves two successive divisions of a diploid (2N) eukaryotic cell of a sexually reproducing organism that result in four haploid (N) progeny cells, each with half of the genetic material of the original cell.
