<h2>Answer:</h2>

The isotope that is not commonly used for dating objects is <u>Phosphorous-32</u>.

<h2>Explanation:</h2>

Phosphorous-32 is most commonly found in organic molecules and is mostly used in biochemistry, molecular biology, and medicine. It can be used to track phosphorylated molecules.  

Carbon 14 is an isotope that is used while determining and finding the age of old and ancient objects. Meanwhile, Potassium 40 is an isotope that is used in determining the age of minerals and rocks. Also, Rubidium 87 is a rubidium element isotope that is used for determining and dating the age of rocks. Only Phosphorous 32 is not used for dating objects out of the four isotopes.

Distinguish between directional, stabilizing, and disruptive selection. Give examples.
pashok25 [27]
Directional selection is a type of natural selection that favors one extreme phenotype over the mean or another extreme. Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution.

Stabilizing selection, also known as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of stabilizing selection is birth weigh in humans.

Disruptive selection is a type of natural selection that shows a preference toward the reproduction of genetic material at the extremes within a population.One of the most studied examples of disruptive selection is the case of ​London's peppered moths.
