Answer:
Various brands of nail polish utilized by Sarah.
Explanation:
In conducting an experiment, two variables are assessed; these are the independent variable and the dependent variable. The variable that is altered consistently to observe its effects is identified as independent variable while the one under examination is termed the dependent variable.
In this scenario, Sarah aims to determine which nail polish brand lasts longest without chipping. Thus, the diverse brands of nail polish she experiments with are designated as the independent variable.
In taxonomy, organisms are categorized based on shared characteristics. As you move to higher classifications, the similarities are broader, whereas in lower classifications, they are more specific. For example, vertebrates belong to a particular organ group.
Organisms within the same phylum can be classified into different orders.
However, species that fall under the same order will also share the same phylum and class because order is a subcategory of phylum. Consequently, organisms within the same order have more in common than those grouped solely by phylum. These shared traits reflect their evolutionary connections.
The diagram is not particularly useful since it showcases kingdom divisions rather than the hierarchical structure of taxonomy.
