Melatonin is a powerful antioxidant and free radical scavenger that helps 'cool down' excess inflammation.
In fact, melatonin is so integral to the health of your immune system
that a lack of it causes your thymus gland, a key component of your
immune system, to shrink in size.1
Because melatonin is a strong antioxidant and is able to cross the
blood-brain barrier, it is thought to help protect against Alzheimer's
disease as well as brain aging.
In one study, artificially aged mice treated with melatonin had reduced
oxidative stress and markers of cerebral aging and neurodegeneration,
indicating the melatonin offered both neuroprotective and anti-aging
effects.2
In another study, researchers revealed that combining daily exercise
with the daily intake of melatonin appeared to have a synergistic effect
against brain deterioration in mice with Alzheimer's disease-associated
mutations.3 Improvements in behavior, learning and memory were noted.
Melatonin's immediate precursor is the neurotransmitter serotonin,
which is a major player in regulating and giving a lift to your mood.
And, like serotonin, melatonin plays important roles in your physical
and mental health. Studies have shown that insufficient melatonin
production can set you up for:</span>
Among ¹⁴⁰₅₅Cs and ¹³³₅₅Cs, <u>¹³³₅₅Cs</u> is more stable.
<h3>Briefly explained</h3>
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. So if we have season one, It has 85 Protons are start 85 neutrons And 55 protons. So we have a neutron to proton ratio of 155 for CCM 1 33. We have 78 neutrons and 55 protons for a neutron to proton ratio of 1.42. 155 is a little high for z equal to 55.
Both of these are also odd. So ¹⁴⁰₅₅Cs is the least stable. ¹³³₅₅Cs is the most stable.

First, make sure all three measurements have the same unit (I recommend meters because that's what the question calls for)
1.0m=1.0m
5.6cm=0.056m
2.1mm=0.0021m
Then, you just want to multiply the three together to get the total volume.
1.0X0.056X0.0021=0.0001176 or 0.00012, if your teacher wants you to use proper sig figs
Im pretty sure it would also be 25
