Questions: Three researcher's fields of study are described below. Choose the term that most appropriately describes each: Miguel is a biotechnologist for the Department of Agriculture in charge of categorizing new genetically modified crops. He puts new flower species into categories based on if they are annuals or perennials, and how large they grow. For example, he classifies a new species of sunflower as a flowering tree because it can grow 12 -feet tall. [Choose ] Phylogenetics Cladistics or Phylogenetic Systematics Nomenclature Systematics or Taxonomy

The answer is: Systematics or Taxonomy.

Explanation for each option:

1. Phylogenetics: This term refers to the study of evolutionary relationships among biological entities, often species, individuals, or genes. It involves constructing phylogenetic trees to represent these relationships. Miguel's work does not involve studying evolutionary relationships, so this is not the correct term.

2. Cladistics or Phylogenetic Systematics: This approach is used to classify organisms based on common ancestry and evolutionary relationships, often using a branching diagram called a cladogram. Since Miguel is not focusing on evolutionary relationships or ancestry, this term is not appropriate.

3. Nomenclature: This refers to the system of naming organisms. While Miguel may use nomenclature as part of his work, the primary focus described is on categorizing and classifying, not just naming.

4. Systematics or Taxonomy: These terms refer to the science of classifying organisms. Systematics often includes taxonomy and phylogenetics, but taxonomy specifically deals with the classification and naming of organisms. Miguel's work involves categorizing new species based on certain characteristics, which aligns with taxonomy.

In summary, Miguel's work is best described by the term "Systematics or Taxonomy" as he is categorizing and classifying new genetically modified crops based on specific traits.
