Answer:
1. The science of the classification of organisms - taxonomy
2. The largest taxonomic category - domain
3. The categories used in classifying organisms - taxon
4. A taxonomic category containing a group of similar genera - family
Step-by-step explanation:
Here, you were given a few terms related to biology and taxonomy and their definitions.
When you're unsure about what a word means, you can look it up in a dictionary - an alphabetically arranged listing of words that contains different information about them, such as their definitions, examples, origin, or pronunciation.
Another thing that could help you out is a glossary - a type of dictionary that contains words from a certain field. For example, you could look these terms up in a glossary of biology or taxonomy.
