Answer: Due to the law of superposition, the lower down the rock is, the older it is.
Explanation: The lower the fossil is, the older it is because new layers were built on top of it
Answer:
Percentage value is used for the predictions rather than the actual measurement this is so because the predictions can be wrong so the value is taken per 100 person or can be defined as per cent.
The actual measurements cannot be used because it is a prediction. Only the approximate value can be used so because there is no precise data.
There is no exact data which can be used to determine the predictions. So, prediction are always made in terms of per cent which means per 100.
Percentages are used in predictions to allow for easier comparison and understanding, especially when dealing with different sizes or categories. They offer a clear basis for approximation, which simplifies calculations, and are suited to the concept of prediction, which involves estimation rather than exact measurements.
We use percentages to make predictions rather than actual measurements due to the flexible and comparative nature of percentages. Percentages provide an easy comparison across different categories and sizes, as they proportionally represent parts of a 'whole' divided into 100 parts. This is particularly beneficial in inferential statistics where we rely on sample data to make generalizations about an unknown population.
For instance, in an election poll showing that a candidate has 40% of the vote with a margin of error of 3 percentage points, using percentages allows for easy comparison and understanding. If we used actual measurements, considering different total population sizes or the number of voters in different polls would make meaningful comparison more difficult.
Percentages also offer a clear basis for approximation, which can simplify calculations in many instances. Scientists often approximate the values of quantities to perform calculations and analyse systems, and percentages provide an accessible means to do this. Predictions, inherently, are not about exact measurements but estimations, so percentages are particularly suited to this task.

Answer:
C
Explanation:
The common ancestors of these owls were geographically isolated, but can still interbreed, as the allele frequencies have likely not changed much.
The common ancestors of these owls were temporally isolated, but can still interbreed, as the allele frequencies have likely not changed much.
The common ancestors of these owls were geographically isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.
The common ancestors of these owls were temporally isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.
Answer:
C. The common ancestors of these owls were geographically isolated, and over time the allele frequencies changed so much they are no longer able to interbreed.
Explanation:
This is an example of allopatric speciation. Allopatric speciation, also called geographical speciation, involves the development of a new species when the ancestral population becomes separated by geographical barriers such as a river or a mountain range. This could also take place when the ancestors of the two species emigrate to another area.
In different geographic locations, the separated ancestors undergo gradual evolutionary changes, ultimately, the the two species become so genetically diverse that they cannot interbreed.
