Among ²⁸₁₂Mg ²⁴₁₂Mg, <u>²⁴₁₂Mg</u> is more stable.
<h3>Briefly explained</h3>
We can identify which isotope in the pair is more stable. Let's review the criteria that are used to determine a stable isotope. A stable isotope will have more neutrons than protons with a neutron to proton ratio somewhere between one and 1.52 On the high atomic number, we're up to 152 at low atomic numbers were closer to one.
More stable isotopes have an even number of protons and neutrons. And stable isotopes have their proton or neutron number equal to one of these magic numbers.
We have ²⁸₁₂Mg with 16 neutrons and 12 protons with the neutron to proton ratio of 1.33. And we compare that to ²⁴₁₂Mg With 12 neutrons and 12 protons and the neutrons to protons ratio of one. So we do have a relatively small Z value. So the new trying to approach on ratio should be close to one. Wherefore ²⁸₁₂Mg , although both of these are even we do have a pretty high neutron to proton ratio for a low atomic number.
So ²⁸₁₂Mg is likely less stable While²⁴₁₂Mg is more stable.

A tree is able to speed up erosion because it break up rocks. This can happen as it’s roots grow through rocks, the water breaks through rocks, etc.
It can slow erosion down because it can act as a barrier to the elements that erode.
The answer is A mutualism
