Answer:
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless.
A nominal scale is a scale (of measurement) that uses labels to classify cases (measurements) into classes. Some examples of variables that use nominal scales would be religious affiliation, sex, the city where you live, etc. Example. One example of a nominal scale could be "sex".
For example, Race is a nominal variable having a number of categories, but there is no specific way to order from highest to lowest and vice versa.

Answer:
It's visual
Explanation:
That's the short answer it's because it visual. A pedigree has squares, circles, half colored squares and half colored circles and lines drawn to show the offspring or marriage. To me, it's like looking at a family tree except it's genetics! That's one way on how it simplifies the analysis of inheritance. Just a note to remind you about pedigrees. Squares are males and circles are female. If the box or circle is half colored with black, they are a carrier for a genetic disease (it depends on what their family has had like diabetes or sickle cell disease).
Answer:
Cambrian explosion
Explanation:
Cambrian explosion is a geological event that happened during the Cambrian age (541 million years ago). In this period, most of the animal phyla (including marine) appeared and their geological record is preserved in the form of fossils. The period lasted for 13-25 million years. Before this period, the organisms were very simple. They were mostly unicellular in nature and were living in the form of colonies.
The remaining three options are incorrect. They are tectonic events that reflect movement of continents in different geological times. None of them resulted in the diversification of (marine) animal phyla.
