Hope this helps.
Technically speaking, depending on the sample, the rock could become “stable.”
The radioactive decay of a radioisotope is expressed as a half-life equation; half-life is the colloquial term that describes how long it will take for half of the radioisotope to decay into another isotope or element. For example (if I remember correctly), Carbon-14 has a half life of 5,780 years. This means that in a 100% sample of C-14, after 5780 years passes, only 50% of that isotope would remain; another 5780 years, and only 25% would remain (half of half). Based on this principle, it seems like a sample could never fully decay because there’s always an amount that smaller than the current amount.
However, if the sample has a very short half life (milliseconds or nanoseconds) the sample would reach nigh-full decay eventually. At this point, it is considered “stable.”
Answer:
The correct answer is VAGINA.
Explanation:
The urinary system refers to the collection of organs that work together to produce urine in human system. The organs that make up the urinary system include the following: kidneys, urinary bladder, ureter and urethra. The vagina is therefore not part of the urinary system. Apart from production of urine, the urinary system also regulate blood volume and blood pressure, it regulates pH and also control levels of electrolytes.
