The answer is A. One way for scientists to gather
information about operons in organisms
is by examining the genome sequence, such as by making use of the intergenic
distance between frames to count the number of operons there is in the genome.
The right answer is Half-life.
Half-life is the time taken by a substance (molecule, drug or other) to lose half of its pharmacological or physiological activity. Used by extension in the field of radioactivity, the half-life, also called radioactive half-life, is the time at which half of the radioactive nuclei of a source have disintegrated.
<span>The term half-life is often misinterpreted: two half-lives do not correspond to the full life of the product. The half-life is in fact the median of the life of a product, that is to say the duration below which there remains more than 50% of the product, and beyond which there remains less than 50%.</span>

Vegetable oil. Oil isn’t soluble in water, if layered properly it will float on top of the water in a beaker as you so mentioned. This is due to surface tension and density and a slew of other things I’m not intelligent enough to describe.
English metric systems are "feet, ounces, inches, etc..." and metric system is "centiMETER, METER, miliMETER"
