Answer:
Superposition
Explanation:
In calculating the relative age of the fossils, the paleontologists use the principle or law of superposition.
The law of superposition states that the rock has layers in which one layer is deposited over another layer. Each layer of these layers is older than the layer which is present at the top of this layer.
Therefore, this method can be used to determine the relative age of the fossils like in the given case, the species A found in the lower layer than the species B because the species B is present in the top layer.
The principle of superposition suggests that the strata or layer of rock or sediment can be compared by assessing the fact that the younger layer remains at the top whereas the older at the bottom. This is indicative of weathering process, the sediments removed earlier deposit at the bottom and which released later on deposit at the top.
According to the given situation, species A is found beneath B the age of these fossils can be compared with the principle of superposition of the strata. A is found beneath the older layers of sediments and B can be recovered from the young or superficial sediments.
They must occur in the DNA, which is in each cells nucleus. More specifically the nucleolus of the cell. A mutation occurs in an allele, where a base triplet (or a codon) gets transcribed incorrectly.
Electromagnetic interference happens less commonly with digital signals because they do not rely on subtle amplitude (signal strength) or frequency differences(cycles in a certain time) to communicate information. Digital signals are readable even with distortion generated from electromagnetic interference noise
