I am pretty sure that the layer in figure 4-1 which forms the cap rock for the oil trap is the layer F that shows an example of stratigraphic traps that includes unconformity, lens, pinch-out in which you can see how t<span>he oil is stuck inside the porosity of the rocks.
Do hope you will find it helpful! Regards.</span>
<span>Group A beta-hemolytic streptococcal causes rheumatic carditis. The most common age group for this inflammation are children 5 through 15 years old. Symptoms include chest pain, swelling of the ankles, a fever, joint pain and a sore throat. People with this inflammation should use antibiotics to cure it.</span>

Explanation:
To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level.
Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm. The regulation of gene expression can occur at all stages of the process (Figure 1). Regulation may occur when the DNA is uncoiled and loosened from nucleosomes to bind transcription factors (epigenetic level), when the RNA is transcribed (transcriptional level), when the RNA is processed and exported to the cytoplasm after it is transcribed (post-transcriptional level), when the RNA is translated into protein (translational level), or after the protein has been made (post-translational level).
Answer:
evolution
Explanation:
For example, scientists believe that monkeys have evolved to become humans.
This clearly has happened over many millions of years.
Monkeys look really different from humans (don't you think!?).
This was just a random example that came to my head.
Hope this helps.
