Which statement is most likely a scientific law? animals need oxygen because it unlocks the energy contained in food. colonies of microscopic organisms grow faster in closed spaces because they cannot fly away. the oldest layers of rock lie below newer layers of rock on earth. healthy foods taste better than dangerous or spoiled foods

The oldest layer of rock lies below newer layer of rock on earth.

Most likely C, The oldest layers of rock lie below newer layers of rock on Earth. Because a law describes an event in nature instead of explaining one. Usually answer choices with "because" in them are ruled out.

Transcription and translation are the means by which cells read out, or express, the genetic instructions in their genes. Because many identical RNA copies can be made from the same gene, and each RNA molecule can direct the synthesis of many identical protein molecules, cells can synthesize a large amount of protein rapidly when necessary. But each gene can also be transcribed and translated with a different efficiency, allowing the cell to make vast quantities of some proteins and tiny quantities of others (Figure 6-3). Moreover, as we see in the next chapter, a cell can change (or regulate) the expression of each of its genes according to the needs of the moment—most obviously by controlling the production of its RNA.
