Answer:
The law of Superposition is where there are multiple layers of rock or fossil. The top layer is younger then the bottom. "The law of superposition is used in geology, archaeology, and other fields dealing with geological stratigraphy." The only problem with this way of determining rocks and fossils is that it gives a relative age not an absolute age.
Answer: The answer for "Which chemical bond most likely stores the most energy?" is C. Double carbon-carbon bond.
Hopefully this helps! :)
If the nitrogenous base is made of two rings that means it's a purine(adenine, guanine), if it's made of one ring that means it's a pyrimidine(cytosine,thymine, uracil).
The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.
The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:
1. Active repressor, active activator,
2. Active repressor, inactive activator
3. Inactive repressor, active activator
4. Inactive repressor, inactive activator
